KATANA (samurai sword)

- The authentic Japanese sword is made from a specialized Japanese steel called "Tamahagane" which consist of combinations of hard, high carbon steel and tough, low carbon steel. There are benefits and limitations to each type of steel. High-carbon steel is harder and able to hold a sharper edge than low-carbon steel but it is more brittle and may break in combat. Having a small amount of carbon will allow the steel to be more malleable, making it able to absorb impacts without breaking but becoming blunt in the process. The makers of a katana take advantage of the best attributes of both kinds of steel. This is accomplished through a number of methods, most commonly by making a U-shaped piece of high-carbon steel (the outer edge) and placing a billet of low-carbon steel (the core) inside the U, then heating and hammering them into a single piece. Some sword-makers use four different pieces (a core, an edge, and two side pieces), and some even use as many as five.
The block of combined steel is heated and hammered over a period of several days, and then it is folded and hammered to squeeze the impurities out. Generally a katana is folded no more than sixteen times, then it is hammered into a basic sword shape. At this stage it is only slightly curved or may have no curve at all. The gentle curvature of a katana is attained by a process of quenching; the sword maker coats the blade with several layers of a wet clay slurry which is a special concoction unique to each sword maker, but generally composed of clay, water, and sometimes ash, grinding stone powder and/or rust. The edge of the blade is coated with a thinner layer than the sides and spine of the sword, then it is heated and then quenched in water (some sword makers use oil to quench the blade). The clay slurry provides heat insulation so that only the blade's edge will be hardened with quenching and it also causes the blade to curve due to reduced lattice strain along the spine. This process also creates the distinct swerving line down the center of the blade called the hamon which can only be seen after it is polished; each hamon is distinct and serves as a katana forger's signature.
The hardening of steel involves altering the microstructure or crystalline structure of that material through quenching it from a heat above 800 °C (1,472 °F) (bright red glow), ideally no higher than yellow hot. If cooled slowly, the material will break back down into iron and carbon and the molecular structure will return to its previous state. However, if cooled quickly, the steel's molecular structure is permanently altered. The reason for the formation of the curve in a properly hardened Japanese blade is that iron carbide, formed during heating and retained through quenching, has a lesser density than its root materials have separately.
After the blade is forged it is then sent to be polished. The polishing takes between one and three weeks. The polisher uses finer and finer grains of polishing stones until the blade has a mirror finish in a process called glazing. This makes the blade extremely sharp and reduces drag making it easier to cut with. The blade curvature also adds to the cutting power. - Розваги
They put their love and determination to that sword. That’s what interests me the most about Japanese swords, they were made with respect and trust.
7:03 "Any particular country that are particulary interested in japanese swords?" "Yes, America and Europe". Well that sums it up, haha!
+Pasquale Franze They shouldn't just give those things away.
The process used to made those swords/katana’s back in the day to stand up to battle use was amazing for its time. But now sword steel with the same spring properties and edge retention can be produced in half the time. As we know firearms drove swordsmen off the battle arena world over but they still have a use even today.
This was a very enjoyable video!
Definitely pure art. How much work they put into it is amazing. Sad too many focus on the lethal aspect of them. Fairly, that is what they are designed to do, but no more. Can look with awe at something that in these days can never be made as well by a machine. That is why it is art.
Why is it a bad thing to focus on what a weapon is supposed to do? It's a tool made for a specific purpose and even though it'll most likely never be used for real, alot of that art is still dedicated to making it as lethal as it is. Of course it also is an art to make the whole of it as elegant as possible but a katana would cease to be a katana if it weren't for it's purpose and the resulting form.
cool
You obviously don't know what you are talking about. Yes they make them razor sharp, but the people who created them, create them as art and only art. They are made to be appreciated. The sword makers themselves say it. They even get registered as a piece of art. You are just ill informed. Even if they did, it's a sword. When they were made for the Samurai, they would grade the Katana by cadavers it could cut through with one swing, and imprint the number on the tang. That's no longer a practice. Stop being a pussy.
Love Katanas, so much beauty in those blades. dangerous yet alluring too
Incredible appreciation for the Katana. Very admirable how much they respect this object
Pretty cool
Very nice and informative Video.
They did make a few decent firearms. One of the biggest mistakes Japan made in WWII was to believe their original 6.5x50mm Arisaka round wasn't powerful enough. The bullet had poor aerodynamics and was initially an unjacketed alloy that was brittle and non-expanding, but the cartridge itself was a truly excellent round ahead of it's time. They have very low recoil and (especially the sniper variant) was so quiet that it was extremely hard to find out where the shots were coming from.
Superb video! Really enjoyed this! Thanks!
Incredible creations.
Beautiful katana swords
such elegant craftsmanship, pure talent
This is great! Thank you for sharing!
Japanese sword is just so beautiful..
Sword casting ... Incredible
This is why I'm a fan of open carry, as well as single action revolvers. A holstered SA revolver can be shot accurately in as little as 2/100ths of a second, 2/10ths often being the minimal requirement for compeittion. Swords are formidable but they're pretty much obsolete in this day and age unless one has an extremely good way of concealing it. In most societies one who's openly carrying a sword will be quickly arrested, or a conceal carry fanatic is going to pull out his gun and be ready.
Such beauty yet very deadly even though these sword have pure soul within those fine magnificent Katana
Excellent, thanks for sharing.
Katanas are epic and fucking awesome. I'm so buying a high quality shinken katana when I got the cash.
aweosme
5:59 So beautiful... I am going to buy a Katana from him when I visit Japan.
The Blades Beauty Just Made ME Cry Y^Y
gorgeous swords
I'm not sure if you are trolling, but I'll bite - that's called hamon, and it's the mark of the differential hardening of the blade. These swords are polished so finely that you will never see a mark on them!
Cheesus Crust, this one helluva vid. Thanks, Sensei.
amazing
very interesting.
a great video - thanks
awesome sword.....
Cool
a beauty
Katana on 5:33 looks like juggernaut's sword form dota2
6:00 What a beauty
(cont) They replaced the round itself with a rimless copy of the .303 Enfield which used devastating yet expensive and meticulously convoluted bullets to make up for their inferior power in comparison to the .30-06, 8mm, or 7.62x54R. The Arisaka could have stood to be improved slightly...but, as you mentioned, the Japanese were and still are disarmed slaves. Howa rifles (sold in the US) are made by Japan, and the Howa made Type 64 and 89 are both excellent military rifles.
very sharp
Material Sciences FTW!
One day i will own one!
It is so fasinating i love the Japanese traditions, culutre, military etc. The Samurai beleaved on Bushido etc. like the IJA, JSDF did. Japan = best country ever
If you love so many things Japanese, i suggest you read the Shogun by James Clavell. I have..
When the swordsmith puts the sword in the water for hardening the parts covered in clay cool down more slowly. So the part that was covered in clay is not as hard as the blade but more resistant to shocks.
(cont) Now I do personally consider a shorter blade such as a bowie to be extremely effective and pertinent to modern survival/self defense and, being left handed, have a pretty solid draw-cut defense against someone trying to arm themselves with a concealed or side-holstered weapon. The problem is; -you- are the predator if you attack first without proof of need and a criminal generally has their weapon out before making demands. The videos shown are of an optimal situation for the attacker.
I think it's like a confirmation to keep swinging, and to establish a pattern or rhythm.
Actually, most people who were samurai were so because their ancestors were. Similar to the nobility in many European countries. If you were born into a samurai family you would become a samurai. If you were born into a farming family, well tough luck. There were a few exceptions though (Toyotomi Hideyoshi was probably the most famous of these).
Oh what craftsmanship real admires of the katana know that these swords are more art form. But can also be a superior weapon in the hands of a master swordsman.
I think that the small hammer hits are like green lights for the big hammer guy to strike
Honor is knowing when to use the dull side of the blade, and when to inevitable use the sharp side. Musashi has taught that the man who measure the blade is governed by it, the blade that measures a man is blinded by it.
Japanese swords are slender, infinitely strong, so beautiful, elegant and yet, ruthless. All who handle these swords must respect, at the highest, its beauty and power so that they will be tame and obedient in your hand.
It's just a sword lol. and not special or superior to any other one.
You want to see a really beautiful sword? Go look up an anglo-saxon or viking pattern-welded blade. Aesthetically, they make a katana look like a rusty knife in comparison.
Mining Forge you might hate katana fanboys but dude xD compared to pattern welded these are useful, pattern welded swords if you have 1 you know that it's shit just made for the look, Patternwelded spines is the worst, pattern weldening is really just a chinese version of Damscus which is where pattern weldening even was inspired by, even tho they couldn't come up to compare with Damascus steel, damascus and patternweldening is not the same thing FYI modern damascus tho is better than most old damascus, I have a Pattern welded vikings art for around 4000 dollar, and i have a old Damascus knife, there is really a difference, pattern welded swords is probly overated next to the katana,
trevipp Pattern-welded swords are over-rated compared to a katana? I don't hate katana fanboys, I just think the media, movies and popular culture have glamourised this sword so much that now everyone, regardless of their knowledge of martial arts and historical fighting and blacksmithing, seems to assume it's the greatest sword man's ever made.
Viking steel wins hands down over the steel used to create the katana- but yes, as you say, Damascus steel kicked arse, nothing else could beat it.
But yeah, I'd say that your statement that "Pattern-welded swords are over-rated compared to a katana" is quite ironic, when there's never been a sword more over-rated than the katana in history- I don't think a pattern-welded blade is necessarily better than a non-pattern welded blade- more beautiful, Definitely, but not necessarily stronger- it all depends on the type of steel.
Well:
1.They're quite thick
2.Are not that strong infact they are often less strong/durable than many other swords.
3.Opinion.
4.Lol so 99% of all people who handled them don't qualify?
i want to try to make katana for my own once
6:00 I can already feel it cutting through my soul! Ouch!
You silly girl. That is what makes the Japanese swords different and unique. The "Hammon" markings are the soul of the sword.
What's the name of the song playing in the background? I love it!
Wow I want a samurai sword
can you pay for it
MarcoManiac probality not
The sword is beautiful. how could I get one?
My eyes started to water when the sword was finished...
I would think the "...only evasiveness" portion of my comment pretty well clears up any confusion.
Ultimate... It's so cool...
I want a samurai sword...
How to I buy this..
What the coast of this beautiful sword. please reply to me about coast and how to i achieve this.
I love this.
go to japan... also, its "cost" not "coast".
Dose he put the clay on the cutting edge or the other side
I'm wondering is it possible to hold three kitanas at once with one hand?
4:00 why does he hit next to the metal? is that a motivational or rythmical thing?
MarcoManiac he wants to be involved XD
No it is the way of giving orders!
Yes
A bullet proof vest is still going to allow you to be wounded (unless it has steel plates inside of it to stop the energy), and it does not cover your armpits, joints, groin, extremities, or head. To be honest your scenario is, at best, a pipe dream since brandishing a sword threateningly toward an armed shooter is probably going to get you shot in the arm, leg, or head. Guns do have their flaws but a knife is much easier to conceal, control, and execute properly in confined or close quarters.
Japanese sword are best.
look's like Honjo Masamune Katana Sword (Legendary)
A good sword is often expensive
Iron Tamahagane Very high prices
Because Japan is considered a national treasure. The price of the sword as well. Higher again.
They missed showing the composite build. Katanas use both folding and composite build (a harder jacket around a softer core.) Search for the user "wakakumo", he posted a lot of excellent videos that show the whole forging process.
I have a wooden Japanese sword. But I hope to own a real one some day
Where available is this in India
my god
that curve ~_~
Lol 7 years and 1 like.
Can someone explain at which part the steel is tempered? I think I missed that part. I am experienced in metal working, but not in sword harding. Anybody?
to time the hit perfectly
so when they are hammering away at the sword why does the man holding the sword tap the anvil?
Gimmeee!!!
sorry.. what country u are from?
what if Crucible Steel was "folded" like this? +Ulfberh+t Masamune?
I do not understand what does the clay on the blade. :(
Hey, my Japanese sword is $500 and it was mass manufactured in a factory somewhere in China. I use it to practice cutting. I know it is not a real traditional Japanese Katana. As if I am going to use a $3000 Katana made in Japan to cut bamboos trees. The real deal will be the main display in the living room for visitors.
but will it blend ?
ΑΡΙΣΤΟΥΡΓΗΜΑ! !
Kod preuzimanja kupovine katane da li je moguće demonstracija oštrice,,
I cried
Quanto custa essa uma katana dessas ?
where is this place that the old guy is doing the interview at????
SugrBop, my ass
good luck hope it works
i mean when the clip went empty and the gun man would be cut down by the sword man
To maintain a pattern for the the assistant hammering the metal.
i know thats is why i would wait for him to wast his ammo and then i would cut him down oh and thanks for reminding me what the metal is called ty dude
that's all true off course,but i think the glory of katanas depends on the importance that japanese gave to them,you know we are just dumb human being always searching for some epic/heroe concept,so what's better than a spiritual warrior refusing to leave his blade even in the 19th century ?? off course from a military point of view this is crazy,but yet this kind of craziness keeps on fascinating us !!!! or at least so i believe !!!
and then the man with a gun gets killed by a drone strike
coi clip xong muốn làm 1 cây ghê nhưng điều kiện k cho phép
CẢM THẤY TỦI THÂN
the best known sword maker is masamune and he made stuff in 14th century
Where's the tsuba on the sword?
I'd like to add that, no, the Japanese didn't invent folded steel, European, Chinese, Mongolian, and middle eastern smith's were folding steel to refine it about a thousand years or more before the Japanese each
Dylan Lewis I Agree Dylan ; Also before the 10th Century, Northern European Swords had elements like Nickel, Cobalt & greater amounts of Manganese. Katana's high carbon steel blades (even with superb laminating & craft work), were not a match for high speed alloy steel.
...
Original Samurai Swords would have broken in a full clash & block with a quality European Sword. It was not until the 1800's that a Katana had a Metallurgical Composition that was deserving of the Reputation & Myth ;
by then, the World had turned to Guns & the glory days of the Samurai were long past !
...
Yeah , too many people over rate Japanese Swords...
1arritechno not to mention the horrible design, the guard is overly small, it's about the same weight as a bastard sword, but not as much reach, and it's likelihood of bending with a cracked ede rather than the blade just flexing
Dylan Lewis That's true, also a lot of people forget that - thrusting a long sword can be more effective in dispatching an enemy ( having a usable point & two cutting edges is the best of both world's ). Even the early long blade Rapiers had a full hand guard , they were a much more flexible weapon. In fact I can think of many broadswords that would out reach & likely better a Katana,,, after all, it's not a chopping contest!
1arritechno you can't even attack the enemy with the guard of a katana
Eray IsMe no one said I was American
@stbridget5 We have a perfectly fitting Name for that in our Language... Scabbard, Sheath, Scheide.. .it is not always necessary to use the Japanese Terms.
i wounder about the cost of having one made now that i understand the process of it if any of you how much it would cost please message me and well talk
Vergil's the one with the katana.
per acquistare una katana ?
Please state the music name!
How to make a perfect hand off mini katana sword
this is a timing process they use between hammering stage and the cut and folding stage - there are better videos available to watch, this one was short in comparrison
