Он поправляет уже закалённый клинок молотком! Это говорит об ужасном качестве стали клинка. Это меч одного точного удара. Если им фехтовать, как европейскими мечами, он просто погнётся. Вся техника удара при вытаскивании меча из ножен происходит из очень плохого качества стали в средеевековой Японии. Я сам кузнец, я знаю о чём говорю. Вокруг Японии больше мифов, чем правды, чувак.

@@Alex_Pervach 1.他用锤子调整的是红热状态下的刀筋，只不过刀条中段被煤灰覆盖，尾部干净的部分可以看出来。如果你所说的“已经硬化的刀片”指的是放入水里还有滋滋声音的刀片的话，我已经不会怀疑你的观察力，而是直接怀疑你是不是酗酒导致脑部永久损伤了。 2.太刀/打刀结构和西欧的长剑完全不同，长剑使用单一的钢材，所以刀匠希望它兼具韧性和硬度，日本刀有时会使用不同含碳量的钢材/铁加工（例如三枚合，类似的现代产品参考瑞典fallkniven的f1系列生存刀），还有刀刃和刀筋也会同时进行不一样的热处理，导致一个刀条不同部位却永远不一样的微观结构（你不是不知道为什么日本刀不可以像long sword一样折弯后恢复吗，这些都是原因） 最后希望你多学习，少妄评。

@@Samyo107 в европейских клинках тоже использовалась кузнечная сварка. Собственно, получить твёрдость и пластичность клинка проще всего именно таким способом. Кроме этого могла применяться зонная закалка, то что делаете и вы, обмазывая клинок глиной перед закалкой. И возможно ещё науглероживание режущей кромки, тоже технология известная довольно давно. Надеюсь, что вы так же знакомы с технологией булатирования стали и выплавкой тигельного булата. К чему это всё? К тому, что узорчатый дамаск сейчас делается исключительно для красоты, а не для качества клинка. Лучшие клинки получаются из моносталей или из порошковых сталей. При всём уважении к вашему мастерству, но металлообрабатывающие станки и поточное производство убивает малый бизнес. Удачи в работе!

@@Alex_Pervach 1.我从不觉得中世纪的产品性能可以超过现代材料，我个人甚至不喜欢大马士革的花纹，拿日本刀举例，九五式士官军刀的量产刀条在一些方面就已经超越了江户时期的普通产品 2.你的误区，你的语境里，“欧洲产品”可以弯折后回弹”，我可以告诉你，同时期中国产品也可以做到，那是不是就是说日本刀很差劲，用材劣质呢？很明显是设计的不同，斩竹席要刀筋正（这三个字我不知道你翻译不翻译的出来），这个动作要求为的就是要减少刀片在斩击物体时的形变，而日本刀本身就是这种特化物，长剑能在后期出场率高是因为战场需要一个可以攻击盔甲缝隙的工具，而日本人把这个工作全权交给了手里的长杆武器，太刀显得反而有些鸡肋，但如果就斩击的流畅性来说，太刀强于长剑，因为牺牲韧性提高硬度的特化，也变得没法像长剑那样45°弯曲还可以还原。

Likely better than a young man, with many years of experience. An expert makes the difficult seem easy.

Thank god for weeaboos. Their katana purchases help keep this craft alive.

​​@@SergeantExtremeConsidering how incredibly expensive and difficult it is for foreigners of Japan to obtain genuine, traditionally-forged katanas, I'm pretty sure none but the most powerful weebs can ever acquire one, much less affect the longevity of this craft. Of course, there are tons of katana-shaped swords you can acquire outside Japan, but essentially all of them use western forging methods and modern metals, unlike the man in this video. And honestly, even this master is eschewing some of the more archaic techniques for modern ones (like using a power hammer instead of a group of apprentices with mauls).

@@Tenchigumi Oh snap! You weren't kidding! A dagger starts at $10,000 USD and a full sized katana at $50,000 USD.

@@SergeantExtreme It depends on the smith and the sword. You can get a dagger for 3000 and a good katana for 8000, of course if the smith is a national treasure the demand for his swords will be higher, and as such the prices will be as well.

@@Tenchigumi "Of course, there are tons of katana-shaped swords you can acquire outside Japan, but essentially all of them use western forging methods and modern metals, unlike the man in this video." Which makes them better, from a functionality perspective. Also, there are many Japanese swordsmiths who moonlight in China (due to the laughable, authoritarian sword laws which limit them to making only 2 swords per month in Japan), so if you really want a katana made by a Japanese swordsmith using the traditional Japanese methods (including starting with crappy, primitive bloomery steel), you can get one made in China for about $1,000. "And honestly, even this master is eschewing some of the more archaic techniques for modern ones (like using a power hammer instead of a group of apprentices with mauls)." A power hammer isn't a modern method. Water-powered hammers (i.e., powered by running water imparting motion to a water wheel > cam > hammer) date back a couple thousand years to ancient China and the Greco-Roman world, many hundreds of years before the Japanese even started making swords.

日本刀独特のあの腹の反りは、鉄を熱しては冷やすを繰り返す事で出来るが、最初の内は誰もが知らず、偶然の産物だったらしい。その偶然を上手いこと利用していた先人達。 凄すぎる。

泥塗ったり、灰につけたり、化学反応とか何も知らずに発見したのかと思うと気が遠くなりますねww

ある時、折り返して重ねて打っていくことで不純物を抜けば、刀は更に強靭になることを見つけた天才がいたんやろな。それを限界までやったのが日本刀なんちゃう？

It's not really dug from the ground, tamahagane comes in this form, because they only can make it the same way, it was made for hundreds of years. It doesn't look like he has apprentices, their job got done by a machine... propably the reason he didn't make a katana, they are only made the traditional way, without machines.

And he doesn't need to use borax flux.

Yea im sure they had that machinery thousands of yeas ago.... dumb ass.

@@patrick3426 "It doesn't look like he has apprentices, their job got done by a machine... propably the reason he didn't make a katana, they are only made the traditional way, without machines."

色んな意見を聞くけど、日本刀を作る上での技術はとうの昔にほぼ失われてるのが現状ってのを聞いかことがあるで

同じような話で今の技術では戦艦大和は作れないという。あれだけの大きさの鉄の塊を組み立てる技術が残ってないんだとか。だけど今の技術はスマホなどのハイテクが作れるわけで、失われる技術もあれば、新しく生まれる技術もあるってわけだね。

ロストテクノロジーやね

良質な玉鋼が無いから

@@user-pf1bu9pi9d 詳しく調べた訳でもないから、もしかしたら違うのかもしれないけど、昔作れたものが現代で作れない訳が無い。同じ材料で同じ設計図のものを作ればいい話。 仮に、この設計図通り作って浮かばなければ戦艦大和の何かがめちゃくちゃだったと言うだけ。 特に、今のような精密さを極めたような技術力と言い方は悪いかもしれないけど、昔のような荒っぽい“人間の力“だけの技術力とじゃ差がありすぎる。 戦艦大和は精密に作られなかったからこそ生まれた偶然の産物とも言える。 この偶然の産物を良しとするなら、現代風にアレンジした戦艦大和を模倣したものは作れる。

はい、これは他の武器とは異なり、伝統的な芸術的スキルを使用して使用される芸術的な武器です

In Japan there must also have been simpler, cheaper and faster made swords that ordinary soldiers have used in battles in the old days. Such swords like this have only been available to the upper class.

子供の頃、剣道をしてましたが、竹刀をまたぐだけで、叱られました。ましてや、試合で頭にきて投げようものなら、即、失格で敗退です。 自分の剣ともいえるラケットを壊している選手を見ると悲しくなりますね。

Awesome job

Thanks for sharing

What about the straw ash?

Nice GK lesson

@@bobbitchin260I think it adds carbon to the steel.

Not supposed to repeatedly heat treat. Especially in the middle of making a sword. Only after making it are you supposed to heat treat though. Seems like a tradition of pointlessness.

The transformation of the edge to martensite, a crystalline structure which is harder but has a greater volume than the softer pearlite structure at the back, also gives the blade much of its curve.

Sie sollten sine Reise nach Japan machen

cause their material sucks, tamahagane is actually is worse than modern steel... its the process that made the sword hard, something called differential hardening or something

This kind of perfection, you will never see that here in the US. Sad.

But you have to understand...Japanese hate non-Japanese

You read my mind.... Do you know how the mud is chosen? I assume it's not just any old mud.

Ok Road house, what's the correct info?

Di daerah saya Lumpur itu atau tanah,, bukanlah mitos tapi fakta klu Ad Jago2 yg berilmu kebal Senjata tajam,, maka ketika pisau atau pedang di tancapkan ke tanah maka Ilmu kebal akan hilang dan senjata akan melukai nya,, Artinya Ad kesamaan dari fungsi tanah pada sebuah pedang,, KARNA katanya kita di ciptakan dari TANAH,, maka akn kembali juga ke tanah😂 Kurang lebih begitu😂😂

It's both to add carbon and silicon (in the mud which is indeed not just any mud), and also to prevent oxygen in the atmosphere from reaching the steel (reducing, not oxidizing). The mud also serves as a flux when the metal is reheated to weld the layers together.
