The video in short: The blade edge is coated in a bunch of VERY hard bits. Bits make it act like a micro-saw. As the knife wears down, the steel is gone and the bits fall off, but a new bunch of bits comes to the new edge, preserving the micro-saw sharpness. Also, If you abuse it too much and it DOES get dull, send it back to them and they'll repair it to be as good as new.
Having declared my dissatisfaction with this sharpener last night ua-cam.com/users/postUgkxDcr-y2Pf6xdnrFHrSP7dl9kpKaCozcSQ I thought about the problem some more. It occurred to me that I might be undoing each attempt at achieving a sharp edge by the repeated attempts. So, I tried to clean up the unsatisfactory result by honing with only positions 3 and 4.Miracle!! A really nicely sharpened chef's knife, more than enough to handle my needs. Admittedly, it did not reach professionally sharpened razor-fineness, but it is now significantly sharper than it was. A bout of breaking down carrots convinced me. So, major apologies to the manufacturer, Amazon, and all happy and potential owners! Follow the directions: don't buy it if you have ceramic blades; and don't overwork your knife blade.

Japanese are number one, not in knives but they are the best in all their product! I am from Tanzania, a chef & hunter! I use Japanese damascus steel knife, for over 5 years but still looks new. I’ve used knives from Spain & German but all were useless comparing to Sukenari nickel damascus wa Gyuto 240mm. Very durable, very very sharp and easy to sharpen it. Now planning to go all the way from Tanzania to Japan only to purchase knives.
but the most interesting one is the re-sharpening process with your own hand, bruh i know its weird but actually I got that zen relaxation while sharpening a knife, like you got self satisfaction if your knife are very sharp by your own
I like how they fucking slowed her voice down and sped it back up to match stuff. It sounded like she slowly decended Into hell, and then turned into a chipmunk. Also wow, that plug at the end tho
......uh, how long you been this stupid? Those two guys in the white suits that have been following you, they just want to talk to you. Please stop running away so they can say “Hi” to you. Please time is of the essence!
Don't let this distract you from the the fact that in 1966, Al Bundy scored four touchdowns in a single game while playing for the Polk High School Panthers in the 1966 city championship game versus Andrew Johnson High School, including the game-winning touchdown in the final seconds against his old nemesis, Bubba "Spare Tire" Dixon.
I had a shaving sharp chef's knife. It went dull in a day. Resharpen and in a day dull again even though I didn't use it. I caught the wife "making it safer" by rubbing the edge on the sink. I kept the knife!
I imagine this knife does stay somewhat usable until all of the titanium carbide is worn away, which might take a while. I suspect, however that it's impossible to get it properly sharp. I'd rather just give my kitchen knives a couple passes over the strop every time I use them and keep them sharp.
Maxwell Super You are missing the marketing point. The customer never needs to sharpen it, so to them it never needs sharpening. Quite appealing for many. Just send the knife back and job done
The thing is, it's never actually sharp. What they say at the start about the knife edge isn't true: a truly sharp edge doesn't need to be jagged to cut--in fact a knife that has a jagged edge like these do is really just tearing the food on a micro level. These knives are like a space-age version of Cut-Co knives, meaning they're like tiny hacksaws. (Just look at the terrible job the knife does with that tomato. Try cutting an onion with this thing and you're going to need a whole box of Kleenex.)
This just means that the knife cannot be sharpened and makes the knives disposable. I prefer Shun's dual core and hikari designs, since they can be sharpened and the two steels used wear at different rates to create a form of mini-serration while wearing.
Most shun knives are overpriced, for what they charge for a stamped Vg10 steel knife you could get a far superior SG2 knife else where. But if your really have the cash to blow your better off looking into forged Masamoto or Sakai knives.
Nikushim - I don't own any Shuns, and do have a couple of SG2 knives. But your pejorative use of the word "stamped" is nothing more than a knife cliche. Stamped knives can vary from the cheapest crap to some of the finest knives out there, depending on the alloy, heat treatment and other factors.
It was not a pejorative use of the word. It was just referencing how the blade was produced, as a number of knife manufacturers produce both forged and stamped blades (which has a huge impact on the cost). A stamped Masamoto Yanagiba might set you back 150 to 200, wile a forged Masamoto is in the 1k range.
Robert Coffey shun is still crap in my opinion in comparison to a moritaka or a konosuke WHICH are within the same price range as shun's and are MUCH better at holding/retaining their edges.
Man of the north People are so used to nameless stainless steel and poor edge geometry that good steel and edge geometry makes it seem like it lasts forever
bill bixby So the blade is serrated? All the knives are microserrated. Some have more toothy edge others more smooth. Serrated cuts better with sawing motion and smooth edges cut better when push cuting. It may feel it cuts sharply but if you compared it to the original state of sharpness you would notice the difference.
The jagged edge does eventually wear down after some time. Look at cpm S110V. It has a high carbide content, but still eventually shows signs of a stressed edge.
Rogertron 85 ceramic makes a fantastic vegetable knife and should be stored carefully and never used for anything else. Always remember to throw that in. You'll get friends saying ceramic knives suck and find out they used theirs to carve a turkey
i dissagree. i had several untill i got my full vg10 steel knife which is one of the hardest steels out there. it gets used daily and i sharpen it less then twice a year my ceramics didnt last that long and cant really be sharpened. at 50 bucks it was as much as a good ceramic knife so i only use my now not to sharp ceramic knife for apples so they dont go brown instantly. everything else vg10 steel ftw.
The explanation is somewhat misleading: a jagged edge is "sharp" in the same way that, on a larger scale, a serrated knife or saw is "sharp", but you can go far beyond that level of sharpness by making it less jagged and grinding to a much smoother thinner edge. What you're getting from this carbide coated blade is a knife that, at best, stays at average sharpness for a long time, but it's not as sharp as would be a properly sharpened bare steel knife ground and polished to as fine an edge as you can get it. It's really more a choice of long-lasting average sharpness vs. much higher peak sharpness but faster wearing.
Tungsten IS used in chef's knives. When blade manufacturers talk of "Blue" steel then it contains tungsten (sometimes called wolferm). Blue steel also contains vanadium, cobolt manganese and other additives to make the carbon steel less brittle. But blue steel has larger particles and as a result tends to not be able to sharpen as much as white steel. Anything that is stainless has chromium as a percentage of the blend, and chromium grains are even larger. Stainless for this reason is even less able to take as sharp an edge as blue or white steels. The Rockwell value is a consequence of the initial quenching process hardening of the finished blade. High Rockwell values tend to be brittle. A blade manufacturer could temper the blade afterwards which lowers the rockwell value somewhat, but makes the blade less brittle and more durable. Any blade with a rockwell value about 60 will be prone to chipping of the edge, and will require whetstone resurfacing / sharpening to retain a clean cutting edge.
OK, so coating the edge with titanium carbide makes it hard and long lasting. But what does the treatment do to the sharpness? A truly sharp edge uses fine carbide steel, and should have a radius of a micron or so, achieved by having carbides of a fraction of a micron in size. Are these TiC deposits smaller than that, or giant blobs on the edge? In any event, no knife is indestructible, and I prefer to be able to repair and sharpen them myself.
You talk much but i think in terms of practice you dont know shit, every knife is jagged to a Micro level, you can kinda remove it by polishing it by high grit stones
You talk much but don't think enough. Yes every knife is jagged at a micro level and can be polished (and I do that with my knives). But good luck using a high grit stone to polish Titanium Carbide - you'll still be polishing the Christmas after next. Some people believe that truly micro serrations help with certain kinds of cutting, but these TiC deposits look larger. And I will always stay away from any knife that I can't maintain myself.
Hunter Kessner Please send me link to your "wit" I wish you a long life so you can see what I mean...I agree that extreme quality steel edge lasts long in the hands of careful person who never touch metal, bones, hard laminated surfaces, glass or else but it is impossible not to
You can buy a cast cobalt knife with dendritic cobalt carbide, it lasts ages and sharpens with two strokes each side on conventional stones. Downside: rather expensive and smaller.
In a sense, the tungsten carbide coating technology is similar to a zirconium oxide (ceramic) knife that the blade stays sharp for longer, but it needs to be factory sharpened. Perhaps it is easier to keep a sharper at home and stay with a traditional knife.
whatever the pro's and con's it's still an interesting idea. The maker (imo) is trying to mimic Wootz steel. As Wootz had natural carbide filaments in it. So, as the 'iron' part of the edge wears down, the ends of these carbide filaments protrude out from the edge (creating a microscopic saw edge) and a very long lasting (and easy to maintain) cutting edge. If you know where to look in India it's possible to find billets of this steel (actually left overs rediscovered/dug up in old forges many hundreds of years old - when the historic Wootz steel mine was active). As I know some modern makers have sourced this material for special blades projects. fyi - I've seen various blades forged from true 'old' Wootz. I advise anyone interested to track down and examine one.
maelgugi absolutely! I have a mixture of diamond stones, and natural stones for sharpening my knives. I also have steel hones, and leather strops that I keep loaded up with green and white polishing compound. I messed up at least one hundred times while I was learning how to perfect my stroke. But I kept at it, and I learned the skill.
If you are careful and know exactly what you are doing, then it will last a LOT longer before it gets dull as opposed to a knife made out of steel. But never needing to sharpen it would only happen if you never used it.
For anybody who wants a quick run down of what this video is I'll explain quickly, they are coating the knife edge in carbides, which make the blade last a lot longer than stainless steel blades, they don't compare this carbide coated blade to high carbon steel blades, or deferentially hardened blades with hamon. These knives are not terrible but when they do eventually go dull, you won't be able to fix them up yourself, unless you know how to coat blades in carbides at home or in your workshops. You will have to send off these knives back to the factory, so they can fix the damaged carbide coating, that of course comes off after much use. Good gimmick, not good for maintaining them at home for most people, I could put the coating back on myself I know how, but I doubt most non smiths who just want a good knife can. So I would say a high carbon tool steel knife would be better for the home buyer, as they last ages and can be re sharpened at home by anybody.
Brandon McCoy , Do they have a lifetime sharpen program, sike. They just made a diamond file shaped like a knife, wow...... Chef Ramsay would be so proud
This video is insane, the guy clearly has noises divulging his secrets to making this insane blade. he want everyone to know just how smart he is coming up with this technique... very selfless, I wouldn't have been able to do it.
I have a miyabi kaizen.any knife Rockwell ,61+ will effectively never need sharpening* what I do for mine is use a leather strop to touch it up every few days. I cut for hours at a restaurant some days so it gets used
Sure, if you make the steel dense and hard enough the edge will last longer but when that knife will need sharpening (and it will at some point) it will be a nightmare to sharpen. I guess this knife can be beneficial for cutting soft materials such as vegetables.
dec 1 the question is after how long the knife shouldn't be too hard because it Will break and shouldn't be too soft because it Will need sharpening way too often that's why different steel materials have different heat treatment
I think there is a translation error. This is a knife that you do not need to sharpen Vs a knife that does not need sharpening. The Owner said in the video when your knife is dull send it back to the factory for reprocessing / sharpening / add Ti carbide edge. YOU cannot sharpen the knife at home!. Anyone still using there Ginsu knife?
That is a great looking knife and I would have loved knowing about it before buying the butcher knife and meat cleaver I got which was made in Germany, and an electric knife sharpener.
Titanium carbide very nice at first but when it dulls scrap it it cost way more to sharpen and the hole knife isn't made of it same steel used on a tree feller great at first but when it loses its edge its caput
i tend to buy cheap knives that i can keep sharp easily rather then expensive knives that has very hard edges. you need good sharpening skills and tools to sharpen a quality knife. plus it takes time sharpening it too which i dont really have. ;)
This is the manner of hype that foolish consumers fall for. I have a feeling that if the knife sells for a while, I will start seeing it a few yeara later, on the Salvation Army bargain bin
It will be perfected when a sound diode implanted in the handle screams "HEEEEEEYAAH" with each stroke that you slice your holiday ham......or finger, whichever.
The best kept secret is in getting a knife that actually can stay sharp for the longest amount of time with the least amount of maintenance while actually being used daily. I know the brand that can do this but it's the best kept secret in the world...to know more you'll have to be ready for Quality

The blade edge is coated in a bunch of VERY hard bits. Bits make it act like a micro-saw. As the knife wears down, the steel is gone and the bits fall off, but a new bunch of bits comes to the new edge, preserving the micro-saw sharpness.

No such thing as a knife that never needs sharpening if your goal is true sharpness. Carbidized blades are a novelty at best.

So I would say a high carbon tool steel knife would be better for the home buyer, as they last ages and can be re sharpened at home by anybody.
... differentially* hardened blades.
@@einundsiebenziger5488 Uh huh.
Does Pokémon music always play here
Brandon McCoy , Do they have a lifetime sharpen program, sike. They just made a diamond file shaped like a knife, wow...... Chef Ramsay would be so proud
They are very rare cause they hold a Samurai soul. Scientists are currently for a way to synthesize Samurai and decrease production costs.
This video is insane, the guy clearly has noises divulging his secrets to making this insane blade. he want everyone to know just how smart he is coming up with this technique... very selfless, I wouldn't have been able to do it.
What is up with her shirt sleeves?
I have a miyabi kaizen.any knife Rockwell ,61+ will effectively never need sharpening* what I do for mine is use a leather strop to touch it up every few days. I cut for hours at a restaurant some days so it gets used
but can it run gta 5 at 60 fps 1080p ?
The way the dialogue between the woman and man has been dubbed reminds of a Dragon Ball Z episode
The angle of the knife makes it so when it wears dow it stays sharp
Where to buy?
Great knife, and the dubbed over voice's where priceless 😆
Sure, if you make the steel dense and hard enough the edge will last longer but when that knife will need sharpening (and it will at some point) it will be a nightmare to sharpen.
I guess this knife can be beneficial for cutting soft materials such as vegetables.
This also means that you're going to end up with tons of little titanium carbide particles in whatever you're cutting.
A fucking knife sharpening ad before this
High en kinfe Vs cheap kinfe over time both will be blunt after a long time
dec 1 the question is after how long the knife shouldn't be
too hard because it Will break and shouldn't be too soft because it Will need sharpening way too often that's why different steel materials have different heat treatment
coat the edge with vanadium then you might have something, or better yet just use chrome vanadium steel to make your knife.
I think there is a translation error. This is a knife that you do not need to sharpen Vs a knife that does not need sharpening. The Owner said in the video when your knife is dull send it back to the factory for reprocessing / sharpening / add Ti carbide edge. YOU cannot sharpen the knife at home!. Anyone still using there Ginsu knife?
Clever idea!!
That is a great looking knife and I would have loved knowing about it before buying the butcher knife and meat cleaver I got which was made in Germany, and an electric knife sharpener.
Dear god did you see how difficult it was for her to sharpen that knife? No fucking way will I ever submit myself to that.
Oceanic dive knives all ready had a model decades ago ... specific use.
Titanium carbide very nice at first but when it dulls scrap it it cost way more to sharpen and the hole knife isn't made of it same steel used on a tree feller great at first but when it loses its edge its caput
Oh Lord, those sleeves! I feel like I'm watching a puppeteer, like the Swedish Chef or something!
i tend to buy cheap knives that i can keep sharp easily rather then expensive knives that has very hard edges.
you need good sharpening skills and tools to sharpen a quality knife. plus it takes time sharpening it too which i dont really have. ;)
This is the manner of hype that foolish consumers fall for. I have a feeling that if the knife sells for a while, I will start seeing it a few yeara later, on the Salvation Army bargain bin
Wateringman I actualy got one and had it for 3months and this actualy workes better that I expected
Mr. unitato
Nice, but a good knife has an expected life of decades if not life time
lol you clearly know nothing about good knives. If you actually find expensive blunt knives in thrift stores, you could make a living off of that.
Wonderful video I would like to buy one of those knife
I once had a Ginsu..
I would chop bricks and then cut paper thin slices of tomaters with it. It never needed sharpening .
what amazes me is the fluctuations in the lady's voice
That is amazing.
Tungsten carbide is harder thats what my sharpener is made of
2:22 when the mushrooms kick in
It would have to be a tungsten alloy for something to be almost sharp for the rest of your life
The only knife that doesn't need sharpening is one you never use
An even before that knife... the Internet, where marketing was transformed forever
My first Japanese imfo commercial
What is this anime?
after a afternoon of whittling I like to drink shine by the fire and get my edge on.
Stainless steel is good like spyder co’s tenacious is relatively cheap and has 8cr13mov stainless steel
It will be perfected when a sound diode implanted in the handle screams "HEEEEEEYAAH" with each stroke that you slice your holiday ham......or finger, whichever.
The best kept secret is in getting a knife that actually can stay sharp for the longest amount of time with the least amount of maintenance while actually being used daily. I know the brand that can do this but it's the best kept secret in the world...to know more you'll have to be ready for Quality
What is the name of the knife?
must be made of Vibranium !
its a good knife for home cooks because most home cooks don't know how to sharpen blades properly..
can I buy the knife in Germany
why do they use detective conan case solved theme song as background music
One of those fantastic places tucked away in unknown corners in the orient that produces unbelievable products. Thank god the world is still big. LoL
