- Quality Damascus knives can cost over $5,000. Their signature swirl pattern comes from layering two different alloys and folding them over each other, sometimes resulting in thousands of layers. This can take master smiths a month and that intense labor accounts for much of the final price.

Why Damascus Knives Are So Expensive | So Expensive | Insider Business
For anyone wondering if Damascus is better than normal steel or if it's just a myth: it is not, however it used to be. The ability to make the mix of carbon and iron in steel homogenous has not always been a given. That means that steel from hundreds of years ago was significantly worse than steel today. Damascus was the best way at the time to make the steel more homogenous thus making it superior to other steel of the same time period. Nowadays due to modern machinery steel is much more homogenous eliminating the need for the folding the steel to make damascus
" Damascus was the best way at the time to make the steel more homogenous thus making it superior to other steel of the same time period." You mean in japan was the steel absolute bullshit and they have to do the damascus way. In euope there was a way better steel.
Agreed
Would you say they both have the same "strength"/durability
@dogs oath perfectly made Damascus would probably still end up technically being weaker just my virtue of how great metallurgy has become, regardless we aren't reaching that limit while doing anything these utensils can handle, even in a larger format its pretty rare man out strengths steel before fittings start to go
@@sentient_slab rather that it being Damascus has no effect either way. What affects is the steel, heat treatment, and how it is sharpened
As a hobbyist blacksmith I know just how difficult it is and the amount of strength that goes into making a perfect Damascus knife. For me, it takes days. But I did make one that is used in our kitchen. One of my children is an apprentice blacksmith, and she is miles better than me. However, only highly skilled craftsmen - nowadays not many - will make a fine Damascus knife, and their prices reflect their art and they well deserve the money they receive.

Amen.
Fake news.
@@TheIRSneedsme Liar.
There is a lot of misinformation in this video unfortunately...
For one, damascus/pattern welded steel is no "sharper" "stronger" or "better" than any other monosteel. Zach is likely using 1084 and 15n20 for the damascus produced here. After forge welding these alloys together, the carbon content within the steel as a whole will homogenize during forging and your end steel will perform near identically to 1080 (if anything slightly worse as extended periods of forging can actually cause negative effects in the steel). It will NOT perform any better in ANY metric than any other knife made purely from 1080. 1080 is also considered a relatively low performance steel in the world of knifemaking. That's not to say that it is bad, but there are plenty of other alloys that can perform much better in a kitchen setting (CPM M4, CPM Magnacut, Zmax, CPM S90V, etc). These tool and stainless steels do not forge well due to carbide volume and so are exceedingly difficult to turn into damascus. Most damascus on the market will be some combination of low alloy tool steels or plain carbon steels with one being nickel rich and the other nickel deficient. To reiterate, these low alloy steels are not particularly tough, hard, etc. and perform accordingly.
Not to hate on Zach here as he does make some nice looking knives and has obviously earned his title as a master smith, but many of the things he says metallurgy-wise just aren't true. At around 5:40 he says that he is looking at scale that has flaked off after heat treatment because "the steel has contracted after it hardened, so I know it is hard". Steel goes through a volumetric INCREASE during hardening and actually expands slightly, doesn't contract. And this isn't what causes scale to flake off either, it's the force of the vapor jacket during quench combined with the rapid decrease in temperature (which does involve a shrinking of the steel) that does that. To any smith's that are here learning, flaky or cracked scale after quench does NOT equal a hard blade.
He's also using sharpness as a metric for performance which says very little about the actual quality of his steel and ht. Given the low alloy steels he is using and the HT he is doing using his forge rather than a temperature controlled kiln, his blades likely fall far below the performance of the theoretical best-of-the-best on the market. Again, not to say that they perform badly, but to claim that your knife is the sharpest, strongest, etc around is pretty ridiculous.
Also to everyone in the comments saying that true damascus/wootz steel is a lost art, it's not, we've recreated it exactly. The recipe is not lost we know exactly how it was made and what is in it down to the .000001 atomic %. We've also tested its mechanical properties and it falls far short of any modern monosteel that is produced today.
Anyway, I'll end my rant there, again no disrespect to Zach, he makes beautiful knives, it's just the misinformation and lack of background research by the people who produced this video that bothers me.

@@hemlatanewar2117 Your neck. At first.
Any knife can be sharp. As long as you sharpen it. Sharpness is irrelevant when determining the quality of knives
@@ziyangwu2578 A good quality knife can be as good or better than these knifes, the worth in these are more about how they are custom-made, not because they are better in any way than modern knifes... in fact a good quality knife made today is probably as strong or stronger than these, the rest can be done with good sharpening, that you can do at home with some practice.
As other mentioned, these damascus steels are "pattern welded steel" that are simply being called damascus. I suppose it stuck since saying pattern welded steel all the time is tiresome and calling it damascus has better marketing appeal.
You can have "damascus" made of bad steels or good steels. It's just a mixture of two different alloys that corrode differently. Nowadays its only real purpose is aesthetic.
Actual Damascus steel was made through a special forging process. Pattern welded steel keeps the lines of the steel grains continuous. Damascus steel breaks up those lines on the molecular level. It's pretty neat.
@@ae3qe27u3 Correct me if I'm wrong, but when you heat treat the blade you bring the steel up above the lower transformation temperature and reform the grain structure..??
@@ae3qe27u3
Special and special, it's iron ore smelted and then put into a crucible and slowly cooled.
The pattern in real Damascus comes from Alloys in the steel, creating alloy banding, which has gained huge popularity in getting out of modern knives, you see it a lot on Japanese Honyaki and even some solid VG-10 knives, can also be seen in the iron cladding on some knives.
@@Masterfighterx if my memory is correct the ancient Damascus or crucible steel have their pattern for un- even heating reaching the melting point at the same time also the un-equal carbon and other alloying elements. like vanadium. that's the reason why they have pattern and also much superior. than the other steels back in the ancient days. a bit of manganese, vanadium in the steel and much uniform carbon distribution and finer grain. even the does pattern are visible in the refined bloomery steel but the crucible steel is much more superior. most modern steel are Vacuum Induction Melting, to increase it's purity and alloy distribution they also Vacuum Arc Remelting to the steel. the most high end of steels are Powder Metallurgy. if I my memory is correct VG10 is an ingot steel that is also Vacuum Arc Remelted. while ZDP-189 is PM steel that have been re-melted and re-spray into an powder like the other high end steel like CPM-S110V and CPM-REX-121. there grain structure and carbide distribution are so small you need an electron microscope. also insane carbide count.
Wootz steel is another term for it. Only recently recreated by metal working scholar/scientists. Pattern welded is an art, and the similarities in blade appearance is what has led to the misnomer.
The craftsmanship and design of the knife are just as important as its functionality. You are paying for the intricate details of the handle, the precision of the blade, and the overall aesthetic appeal of the knife. While it is true that any knife can perform the task of cutting, the experience of using a well-crafted knife is unparalleled.
I don't know about that but cost certainly plays a part in how you treat an object, if anyone thinks these patterned knives are better then none patterned its a placebo effect and they probably look after them way better.
$17k to cut a tomato is not “unparalleled”

I'm from Damascus the old city and I'm very impressed by this industry , I wished if someone talk about the history of the Damaskus steel
Isnt it sad that Damascus today has nothing to do with this wonderful masterpiece? Dont you wish that these knives could have been made in Syria?
@@ecoideazventures6417 who said it isnt? the name of this steel forge is the same of the city still.
Is it ok out there dude ?
Cheers from San Diego California
Their origin isn't from Damascus haha like a lot of things the west name things after the closest region from which they've obtained them but that nt necessarily where theyre originally from. Its called wootz too and the origin of that word doesn't lie in Damascus.
@Ecoideaz Ventures this style of damascus steel has nothing to do with Damascus. The original damascus steel is what we call Wootz steel today. This is just pattern welded steel that resembles the eastern made wootz steel that was mostly traded in the city of damascus in the old days. Most of those steel were made in old persia and India and not Syria.
Thank you to business insider for putting an old traditional Indian sword making method, in India it is also called Wootz steel and originated in Southern part of India
It's incredible the appreciation you'll have for something with a little investigating.

I learned a lot about making knives by watching "Forged in Fire". I absolutely love these types of shows that involve either cooking or building something (American Chopper, Monster Garage, etc.). Thanks for the education.
I had no idea that the process of making a Damascus knife was so intricate and time-consuming, involving multiple layers of folded steel and intense heat treatment. It's amazing to see the level of craftsmanship and attention to detail that goes into creating each knife, and it's clear why they are so highly valued by chefs and collectors
waste of time these days, if you think about it. Nowadays it's all of decorative purposes, as we can get better quality steel cheaper, faster.
@@ytuser13082011 I think blacksmiths and knifemakers mostly just think it's fun to make, plus it does look cool.
I've tried making Damascus in my little hobby-forge but I haven't had much luck setting the forge-welds.
Thousands of layers sound extreme, but it's kinda like RAM, because everytime you go up a notch, the layers/ram double, because you fold it and create twice as many layers. Weird description, i know 😅
@@arquloc0893 It's called "exponential doubling"
@@ytuser13082011 right, but people care about art, effort, and craftsmanship in their strivings. the most efficient thing is not the best thing.
There really is an art to making a good Damascus knife and depending how you make it some ways easier than others old school vs new school.
Just think its cool that this art has been around for so long and they used to use meteorites which become the few to the great
Amongst all the people I admire, the ones who lives their life and dedicate it to their passion are on top of the list
Pretty sure it is sharp, but I just love the artistic pattern. The knives are a work of art.
Those Damascus knives are expertly carved out to form that shape. The intricate details on there justs look absolutely stunning.

paying for not just the work n the time put in to produce the outcome, but their experience n knowledge that made it possible to work the way they do to produce the outcome is the key.
just as a very important distinction, this is NOT damascus steel, this is forge-welded steel. damascus steel is a crucible steel. this is forge-welded steel that emulates the pattern of damascus steel. the type of steel is called "watered steel" that results in the pattern of different alloys/carbon concentrations. damascus is the original, and is a crucible steel. fold-forged steel is another type of watered steel, but it is NOT damascus steel.

I thank him for using a more traditional approach to the Hada technique, in witch he actually folds the steel and doesn't cut and restack.
the thing is for a low layer knife like that it is possible but when i am already days into the damascus forging i don't take any risks and i grind and stack. thats the reason that most will just grind and stack
One day when I can afford to buy one I'll go crazy on it and I want to tip the Smith what he deserves along with his price for the products. Mad respect to all of them who keep the art going
I had a dream that I didn’t have a knife when I needed one. It was a very specific looking knife that I was missing. Two days later, I was gifted a Damascus knife at the beach by a friend. It was the same shape as in my dream.
Before that, I already had a profound appreciation for the craftsmanship that went into Damascus blades.

The "Forged in Fire" show frequently has guests make damascus blades. It's cool to see it done when it's not rushed and without real time to plan.
You should cover about Karambits and Butterfly Knives next time 😆 includimg their floats
The most impressive thing about this dude is that he was able to become a master heat treating with a forge.
That shot of him staring into the forge with the snow in the back goes so hard 🔥🔥🔥
i envy people that can create wonders with their hands...it's really important to have a skill
FYI, damascus does not make you knives sharper, you can get a VERY hard homogeneous steel and make a sharp knife that holds edges as good as damascus. I'm a home chef and i have a few VG10 knives that can cut on touch (sharpen by myself). problem with razor sharp knives isn't with the knives themselves but the user, anything will get blunt if you abuse it, taking good care makes you knives last longer(RIP my old 10$ SUS304 that i had been using for the last decade).
Really well done video. I like how you mention, how damascus knives perform similarly (in reality likely worse) to other high end knives. The myth of them being better simply isn't true. What's true about them is that they are real eye catchers and require certain skills to make.
Also this craftmans damascus patterns look stunning.
The magic of damascus isnt the steel, its the fact that they're almost all hand forged and are of a significantly higher quality than a factory blade.
@@sygnusadun4832 yeah, I was also talking about hand forged knives, of which there are damascus knives, 3 layered knives or monosteel knives. the latter 2 tend to be more efficient than damascus in most cases.
@@CRO-Palacinke-D.C Thanks for the feedback, but I must respectfully disagree. What is your basis for that claim? The only discernible difference between a hand forged damascus knife and a hand forged monosteel or san mai knife, from a metallurgical standpoint, is that the edge presents with two distinct alloys rather than one. Technically one alloy is ever so slightly softer than the other, but this is way, way below the level of human perception. And, importantly, *either* alloy is suitable for use in a monosteel or san mai blade on its own.
You should check out Kyle Royer on UA-cam. He's a master bladesmith too and makes absolutely beautiful knives and swords with Damascus steel.
@@zackjonas7775 @Zack Jonas Cool to hear from the blacksmith himself, thanks!
I totally agree with the reasoning you gave.
My "performing worse" comment stems from damascus knives being treated in acid and having an overall well polished surface, which creates more friction when cutting and worse food release than say a hammered finish.
It's overall only a slight disadvantage I'd say. Also I don't own a damacus knife yet (except for the Kai Shun I started on years ago) therefore I can't argue from personal experience.
oh wow. iaido is my martial art and I've been into japanese steel for that reason. I have so much respect for blacksmiths and this was an amazing video.
i got a set of 6 of these beautiful blades thrown in when i purchased a belly blaster on a late night telemarketing show. believe me once you use them nothing else feels the same
modern pattern welded Damascus Steel is not the same as historic Woots (Crucible steel) Damascus.
And the reality is that modern pattern welded steel is simply for decretive purposes.
y'all should do a profile on Kyle Royer if you want to see a prodigious master bladesmith at work, and I say that in no way to diminish the work of Zach Jonas. . . but Kyle's work is simply exemplary.
The knife from this video look ugly, his pattern knife look amateur compare to kyle
@@heydaddy2471 I mean, look. I may agree with that. . . but I'm also not really wanting to tear down smiths who are way, way, way, way better at working metal than I am. I think Zach makes pretty af and nice knifes. I think kyle is. . . .um, a lot better at it. But both are really good. Royer just takes it to another level.
Its so great that he's working on that masterpiece with that weather.
Zach is an artist. Tremendous respect.
In modern steels, ''damascus'' is purely cosmetic. You Layered steel back in the day to remove impurities, and that was still not called damascus steel.
Actual Damascus steel looks more like the knives you see (Many from Japan nowadays) with no layers but there is alloy banding on the single piece of steel, which can also occur in a 3 layered knife, which looks way cooler than pretty much any pattern welded (''damascus'') knife.
Yeah my next knife will be Japanese, but my German and American knives are just as good imo
Amen.
Yea, it used to be superior back in the olden times, but in today times, a good quality regular steel knife made in a high end factory is just about perfect for any kitchen.
Still tho, looks beautiful. If money was not an issue, I'd have it in my house.
something I've learned about Damascus knives from owning one, they last forever. My mom got one in the 1960s (2,000 layers), it's lasted through 63 years of cooking.
Damascus knives and the sound of handpan. Perfection ❤
In short:
They are both aesthetically magnificent and realisticly practical
They are a pain to work with, it's like the blacksmith need to roll the dice a thousand times and they need to roll a perfect 6 every-single-time.
At this point, this is more of a type of art then a hobby
Damascus is just cosmetic. Most knives can be sharpened and be great to use.

@@artimuos903 Gonna cry?
let me just take some confusion out of you, which i used to be confused about.
a. any knife can be sharp enough to do the see through vegetable cut shots seen in this video. the difference is how long a knife can hold its sharpness.
b. damascus knife making technique used to be the best way to get a mixed steel knife. now it's possible for any knife, even without the swirls. because technology.
c. you can get one for the novelty of it. but a victorinox will serve you much better and is usually way cheaper. it's what professional kitchens use.
They're gorgeous knives but they really gassed up this whole "Damascus" thing. In reality, a well sharpened knife between 50-400 dollars will let a skilled chef cut those paper thin slices of anything. And if some idiot wants to snatch it up to open a can, or knocks it onto the floor, it won't cause the same sort of pain. Not to say you shouldn't buy a knife like if this if you really want to, they're just not the atom splitting nanotech monomolecular sci-fi blades they're made out to be.
They also leave out the fact that whats called Damascus steel is made from Wootz steel or crucible steel, what they are showing in this video is a Damascus pattern made using a technique called pattern welding.
I can also cover a space on my wall just as well with crappy art as with good, or drink from a plastic cup rather than handmade ceramic. The point is beyond utility,

If you're looking for sharp knifes, you're probably better off with Japanese chef's knifes. But I'll have to admit that Damascus steel knifes patterns are indeed very beautiful
japanese artisans commonly use damascus cladding with other steel cores. sharpness therefore should be identical, food release is worse though.
@@CRO-Palacinke-D.C Modern steel doesn`t need to be layered. A high quality industrial steel is as good if not better than some damascus steel. Nowadays its for looking pretty but not for performance.
@@sebasstein7014 yep. Even AEB-L and AUS-8 is good enough for monosteel
@@sebasstein7014 they don't need to, but in most cases they are layered. i'm not talking about mythological 1024 layered katanas, but the 3 layer formula. 1 core steel which has really high hardness and therefore is brittle surrounded by a softer steel to make the knife more resilient. the softer steel isn't present at the edge of the knife and therefore doesn't make the cutting any worse. using damascus or another stainless steel as cladding is almost the same, but damascus causes food to stick more than other claddings (because of the acid process and near mirror finish).
there are also monosteel knives with no layers at all, but i'd say they are far less common.
that's so insulting to read
Its not damaskus, its layered edged steal with chrome and carbon inlays..
actually damaskus more looks like big mixmatch with a grainy ricy structure from the interaction in the crucible.
We are the Damascus kitchen knife factory in China. I agree with the explanation in this video. This is also the production process of our factory to produce Damascus kitchen knives.🥰🥰🥰
A master blade smith can make any high carbon steel knife razor sharp. Also there is a small disclaimer that needs to be addressed: this is not true Damascus steel. Damascus steel was made from crucible steel from the Middle East and got its name from the city of Damascus in modern day Syria. The type of steel this video is showing is actually pattern welded steel which has been around for centuries. True Damascus steel has not been successfully made for a few centuries due to the Industrial Revolution began in Europe, and its pattern was based mostly on impurities in the steel such as vanadium and through heat treating and tedious thermal cycling which was only discovered only a couple of decades ago. I personally like both of these steels especially pattern welded steel but a lot of people don’t know the difference between them and it irks me that the trade name misleads people.
Amen.
India, not the Middle East
I work in aerospace and specifically the heat treatment department. I started in ‘06 and I’m still there today as the department lead.
Granted, we work with aluminum and not steel so I’m sure there’s differences I’m not aware of.
Heat treating is very specific. A certain temperature with a very tight tolerance. Obviously this guy is very skilled and I guess has developed the ability to “eye ball” his treatment process.
From the way it was shown he has no temperature gauges and the knife wasn’t being evenly and precisely heated which is essential for the heat treatment of aluminum anyways.
Are there many differences in the process between steel and aluminum? Obviously heat is a big difference! But the process overall how he performed it I’m just curious as to how it’s effective with the lack of precision.
I've been making knives full time for about 6 years now, you can sort-of eyeball a simple carbon steel in the 800-850C range by colour, but you are absolutely better off using at least a thermocouple, digital thermometer and more controlled kiln to get the exact manufacturers specs and that's the same with the tempering process. When you get into high alloy tool steels and stainless, its all done in an oxygen deprived environment to avoid decarburisation of the steel's outer surface, so its typically done with a gas injection into the kiln or a stainless foil packet.
That's a whole other bundle of temperatures which typically start in the 950C all the way through to 1200C depending on the alloy you're working with and they can sometimes have very high tempering ranges of sometimes 350-500C to knock the hardness down. You won't be doing it with an eyeball, the OHS side of me that used to work in engineering means I will rouse on people looking at high infrared emitters and bright light sources without eye protection :)
What got missed though in this video is the blade geometry, he has some superbly dialed in kitchen knives there which are wafer thin, super sharp and even if they're a bit dull after a days work they're still going to cut very well. That said, if you're a bloke looking for a good knife, get something in a modern stainless with a lot of vanadium and chromium in it and you're probably well on the way to a knife you only have to sharpen maybe once a month of hard, every day use. But how it cuts- still all about that fine geometry of knife behind the cutting edge
I'm not a blacksmith, but my father and grandfather were so a little of the knowledge has found its way into my brain. With steel you can get a decent estimate on the temperature by the color of the hot steel. These blacksmiths can get away with "eyeballing" because the scale that they are working at is fairly small. As the work increases in size it gets much harder to do that and have the work survive the process. Knives, swords, and tools are at a size that doing it this way is doable, but even then it is a gamble.
I think I have seen videos of some blacksmiths actually using gauges to get more accurate results. But those things are expensive and smiths don't really need that level of precision typically. They can if they want, but a lot of times the extra precision is just kind of wasted. I am fairly certain however that in an industrial setting it is much more important for accuracy to maintain a consistent product. At the end of the day the effectiveness doesn't need to be super accurate, it IS only a knife. Even with the price tag.
I know nothing about how heat treating aluminum works however so can't say anything on how it compares unfortunately.
@@krissteel4074 thank you for the detailed response! I know nothing about tempering of steel! We use to work with aluminum and titanium when I first started there but by ‘07-‘08 we were working exclusively with aluminum so I don’t really remember the process for titanium!
I knew steel was much higher temps but that was about it! I don’t even know the alloy types for steel 🤷🏻♂️
@@VeshAeryn I appreciate you responding! We work exclusively with aluminum so I don’t know anything when it comes to steel aside from it tempers at much higher temps than aluminum.
Obviously working in aviation we have very specific requirements. Our tolerance is +\- 10 degrees on the majority of our parts. Depending on the alloy we mainly use 3 temperature sets 870F, 920F, 1000F but that’s the highest!
I started in March ‘06 when I was just 18 years old! I had taken my GED test in Dec ‘05 and in Feb ‘06 I got my results and certificate! My uncle worked at this plant and said if I passed he would help me get a job there. Once I passed and filled out my application for two weeks he kept pestering HR until they finally brought me in for an interview. I had 6 different interviews! The plant manager showed me nearly every department and supervisor. After the last one I asked what was going on? He finally said “Well none of the supervisors want you just because your so young and inexperienced”. He said there’s one more department that he was overseeing because they didn’t have a supervisor, he said it’s called Heat Treat. He asked if I was interested and I was like I just want a job idc where! he showed me around and offered me the position!
The first month tho I didn’t even work in heat treat, I started during a stretch where they were getting recertification and Boeing was doing an audit. They didn’t want me messing it up she they stuck me in shipping for the first month.
I’ve survived 4 separate lay offs over the years! Many many supervisors and managers haha. In 2014 I accepted the lead position. In 2019 our supervisor was fired so I was hopeful I would get it! I did my interview but unfortunately they decided not to hire anyone. They had the supervisor of another department run his and my department. Since then tho I essentially I am the supervisor without the title or salary 😒. He has passed a lot of the responsibilities off too me which I think will work in my favor when the time comes to fill that role. I’ll be able to show I’ve been doing these responsibilities and am prepared.
They’ve don’t these multiple times in other departments having 1 supervisor oversee multiple departments and it never lasts. It’s been 3 years and he’s really burnt out! It’s alot if work so I’m hoping buy the end of this year I’ll be able to take over the position permanently
@@chriscampbell3417 If you want a good guide to the heat treatment of steel I'd recommend a book called Knife Engineering by Larrin Thomas. Its not too heavy in terms of science but there's enough science to get you started. He also has a website called Knifesteelnerds and a youtube channel by the same name.
Have they truly figured out the ingredients for the ancient Damascus steel? That's great.
God bless.
They haven't this is just a pattern welded "damascus" knife, the recipe and know how of ancient damascus steel was lost when the last person in the master-pupil chain died without transfering the knowledge to a succesor.
The technic the person on the video is using has nothing to do with ancient damascus steel, since he's stacking different layers of metal and ancient damascus steel was obtained with the use of a crucible.
Story should also cover pros and cons. Like long term use if it will rust or no compared to stainless steel.
I've always appreciated the quality of a damascus blade, but I've never cared for that pattern. If I had the money to buy one, I would have to decide if I want quality or visuals more.
If you're buying Damascus then you're buying it for the visual, so get the one you like the look of.
As a chef whos spent an embarrassing amount of money on knives, there's no reason to spend more than $100 on a knife unless it looks really cool.
This is pattern welded not actual damascus steel. Because there is no such thing as "damascus" steel. Damascus was a hub for sword production, using sourced Wootz ingots from India. We do not know if forge welding techniques used today were the same, which created the "damacened" properties back in the day. Closest modern approximation is the katana, using tamahagane steel. Where different parts of the same ingot are combined with forge welding, layering to form the desired properties of the finished sword.
Definitions change pal. stop holding on to definityions from over 200 years ago.
@@notabrit3025 So we should forget history and make up our own or follow misinformation. Monkey logic.
do you call it velcro or do you call it hook and loop, kleenex or facial tissue , tupperware or plastic storage boxes
Amen.
If it cuts through a lemon or tomato , you know it's PRICELESS
Thanks for revealing his secret of making these knives now I'll make the knives myself
$5,000 knife that'll be sharpened on a $10 knife stone
good Japanese wet stones are also very expensive :D
To cut the worst quality tomato you could ever buy.
@@d0nnerknispel64 yes they really are
I don't think random people cooking at home would buy this but alright.
@@smolbean2263 these are Damascus steel swords and if they are real then it would need a wet stone to sharpen every once in a while not all blade or swords can hold an edge forever
The history of Damascus steel is really interesting. The origins of Damascus steel goes back to South India. Making a really good quality steel which didn't rust easily and was strong enough to take the wear and tear of warfare was known to black smiths of these parts of India (even current Shri Lanka). Here steel was and is still called "Ukku". Indian Kings wanted horses for warfare and Arabians had best horses to offer. Indian Kings bought horses and sold swords in exchange. These swords ended up with Turkish Sultanates. The Ukku got distorted in to "Wootz". That's why even now Damascus steel is also called as Wootz steel. Then Crusades began. When the Christian Western powers met with Muslim Turkish armies in battlefield they were really impressed with the quality of the swords. Since they found these steels in Damascus, they just called them Damascus Steel.
Arab derived from Sanskrit word ARAV means 🐎 horse
@@cardrift4515 What is your source for that claim?
The languages come from completely different language families. “Arab” is an endonym probably originating from earlier Semitic languages.
@@Nick-zl5xf it doesn't matter though it comes from Semitic family, almost 90% words have root in Sanskrit
@@cardrift4515 once again, what is your source. There is very little evidence to suggest direct Sanskrit influence on the Arabic language, let alone the “Arav->Arab” connection you suggest
@@cardrift4515 wow I can't believe how easily you chat shit, another typical Indian haha
I seen many knives but this one is tottaly amazing for me.
So informative!!!! Wow, such hard work goes into the knifes
You can get cheap Damascus knives made in the same pattern welded and twisted sort of styles as this for as little as 20$. Damascus is not at all important to determine if a knife is good or bad quality and is purely aesthetic.
Those aren’t true Damascus blades tho
@@b_bogg Neither is the one featured in this video.
apparently you know very little about what your'e talking about. Additionally a $20 knife will come from a part of the world where the quality of labor laws is nearly non existent and the raw materials are impure.
@@monolithknives931 Man there's about 5,000 amateur knifemakers trying to get their material costs back on Etsy right now, right here in the US.
@@b_bogg Lol Damascus isn't magic. A knife made out of CPM S110V (a modern "super-steel") isn't _that much better_ than a $40 Cisco 8" Classic
Me remembering that these damascus knives aren't even made by real DAMASCUS steel.
Incredible, didn't even know about these before.
Been seeing all these praises of Damascus steel knives. Back in the day remember warnings not to fire modern high power ammo in Damascus steel firearms. How is it we are suddenly in love with Damascus steel???
I thought the making of true damascus was lost and in truth this would just be “watered” steel
There is no such thing as '"true damascus", as someone mentioned in the comment section, it was place of trade where they inherited Wooltz Steel which originated from Tamilians. There are two veils casted over to hide Tamilian history; the credit being given to Persians and dubbing it "damascus steel", while the other being stated by some informative individuals but not accurately saying it was solely from Tamilians instead of including 'India', as a whole - when India was not a country back then, and back then the large land area was called Bharatham by the Ancient Tamilians.
(Copy-pasted from another comment of mine)
Sooort of. First, what you see in the video is unrelated to historical Damascus steel. It just looks similar. But as for Damascus being lost... not really? Sort of. Various forgemasters and researchers have rediscovered what is almost certainly the general process, but we may not know the specific details. It's like trying to make your great-grandma's soup recipe. You can know how to make soup, you can know the main ingredients, and you can know everything she had in her kitchen, but you don't know if you're using the same spices in the same amount as your great-grandma did. Or if she wrote that she puts an egg into the broth and you put in a chicken egg, but she actually meant a duck egg because her neighbor raised ducks.
We can make steel that looks and acts like historical Damascus steel through a crucible process, creating "wootz" steel or "crucible" steel. As far as we can tell, it's the same method they used... but we don't know exactly. It's a close-enough method that we rediscovered, but the details have been lost to time.
With modern "Damascus" metal, there's basically no actual benefit over regular old steel knives, they mostly just look better. Like a 1000 years ago Damascus steel knives and swords were legitimately stronger and much more hard to produce than regular metal items, and they were expensive because of their rarity, actual strength properties, significant difficulty in manufacturing versus regular steel, and of course the intricate design patterns. These days "damascus" is pretty much entirely cosmetic term, and the price is mostly depended on design, because the diffuculty of manufacturing entirely depends on design required. Modern damascus knifes aren't actually that much stronger, sharper, or more durable than regular modern steel. They do have some advantages over regular steel, but 99% of Damascus steel items is in the looks, not function.
I'm Definitely gonna out those in my To Buy List!🤯💯🛠️🇺🇸
My goal has been for years to replace all my knifes with damasks blades. I have one so far and it cuts like Diego said, it’s an experience for any professional chef or home chef. It was a pretty penny to buy. ❤❤❤
does it stay sharp? if not could could explain how you maintain it's original sharpness?
But in order to be considered Damascus steel doesn’t have to be made in Damascus? 🤷🏼♂️ 👀
If anyone has to ask why damascus is so expensive they are brain dead. Go out and try to create a pattern like that in a block of molten steel then come back and ask again.
Damascus is so beautiful on blades 😊
Solid information through this whole video!
As a chef, I can tell you not to be "scared" because the price, once you buy one, it will last you a LITERAL life time if treated properally. Had a colleague whos knife was older then me, and I am 23.
I have german chef knife I inherited from my mother, and she inherited it from her mother. So yeah. slightly longer that 23 years. Needs sharpening.
up to $5,000? NAH. a $200 japanese or german knife is way better value and will last just as long with proper care. damascus knives are very overrated and very overpriced.
Does the knife lose it sharpness? How long is its sharpness last considering its price?
Any knife can lose it's edge. Typically knives like the one in the video have a high hardness scale, and will definitely last longer than a cheaper knife. But there are also really good knives out there that are affordable.
It will be no sharper than a normal chefs knife and it will lose its sharpness as a normal knife during use. It is the craftmanship, amount of labour and looks that make these knives expensive. It is not "magic steel".
It should never lose sharpness at this price
@@Rakadis somewhat misleading. there definitely are advantages to hand forged knives atrributed to high compression while forging while also making different grinds possible. yes, damascus isn't this mythological magic steel, but when only used for a damascus cladding with another core steel (think SG2, aogami super , etc.) it definitely has a better edge retention and better maximum sharpness than an industrial knife with a rockwell hardness of 55.
still; even the best knives can dull quite fast (let's say 6 months for home cooks for it to become well noticably less sharp). that's why it's a good thing to learn to hand sharpen if you like using sharp knives.
@@Rakadis Not entirely true.... Custom knives made of Damasteel (pattern welded steel) or monosteel (singular alloy steels) can be heat treated better than production knives, we also tend to use better steel, almost always better steel than high production knives.
This man have my full respect for him❤
❤
Kappabashi Dougu Street in Tokyo, Japan, is also popular among foreign tourists and top chefs , because Japanese knives are produced using samurai sword-making techniques and can cut well.
Imagine the pain when u drop this knife on the floor on its sharp end
thing about most high end knives is they tend to be really brittle. if they fall on any side chances are they just break.
Its actually expensive because the makers first have to unlock colors, then gold, then platinum, and find a map to take longshots before damascus becomes available.
Metallurgy student here: can confirm 100% facts
I got a set of those magic chef knives from the home shopping network. It was a 3am impulse buy, but I am so impressed! I used them when we put up paneling in my trailer home, you know cutting out the holes for the electrical outlet. And another time, cutting off the dingle berries from my dog bucky. And they still slice tomatoes like magic.
Having a high quality knife is worth every dollar you are willing to spend on it. When you handle and use them, they are an extension of your soul and skill.
"while high end mono steel knives may perform similarly".... This is the key point. Everything that follows this phrase is just about how it looks and how it's made. Very symbolic of the current hipster/artisan fad
First of all it's a pattern welded steel knife as we lost the means to make Damascus steel which comes from wootz iron which is was crucible iron that was found in India. Second it's expensive because a pattern welded steel is harder to make and require ample knowledge of what steels would work well together and years of practice to learn to achive the pattern achive the pattern your want consistently. Lastly pattern welded steel are both of similar quality to other steel knifes the only difference the pattern that comes from the diffrent carbon Contents from the steels used and the user of the knife. There are better quality steel outside of pattern welded for sure but the whole idea that pattern welded steel is better is a myth that was propagated by the use of actual Damascus steel blades which where again is just here say.
Great content from insider as always ❤️

one day I'll become a master as well and produce artistic looking blades like these
This is absolute horseshit. What we call Damascus steel now and the historical term are different. The modern version is what is described here. It does not produce a superior blade. The best it can do is almost as good as a mono steel or San mai steel blade. The problem with Damascus is, every single weld is a potential point of failure, and some faults are undetectable. If you start with a bar of mono steel and grind it to shape before heat treating, you can know that it is utterly free of structural flaws. That is not possible with Damascus. Damascus requires forging, with always risks introducing stress flaws. Historical Damascus was just steel that came from the region of Damascus, and they likely had access to a source of iron with additional elements that produced good steel for swords. The properties of steel can vary considerably based on the specific alloy.
