It's rough, but I used machine translation. That's a difficult question. To be honest, I don't use Tamahagane just because it's Tamahagane. I use it because I like it. Using Tamahagane makes me realize that I am not a significant existence. I have a naturally arrogant personality, so I believe this is a very valuable experience that I should be grateful for. Tamahagane varies in material each time, so the manufacturing methods are all different down to the details. There have been many times when I felt uncomfortable with Tamahagane that didn't match my expectations. However, recently, as I've adapted my methods to suit the materials, I feel like my personality has softened. I'm not smart enough to talk about cool things, so I can only express myself with shallow words, but the biggest reason I use Tamahagane is that it makes me feel that "I am able to live thanks to the blessings of the Earth."

Rest in peace Ford I’m glad I stumbled across this gem of a video thank you.

😍😍

United States soldiers stolen ower 3 million Swords from Japan after ww2.

This guy used to get swords from people to polish, and just keep them. Karma has caught up to him😵😵😵😵😵🤢🤢🤢🤢

Where i can buy tamahagane??

木原さんがまだ50代なので30年前の映像か

Blacksmith。炭で顔が真っ黒になるから？

Is it harder to find iron ore in Japan?

I would argue that a cutless was better for fighting. The Katana was nothing more that a show peice. A symbol of status.

Супер!!!🤗💪😤

Wheres the full length video?

This intro is legendary!🔥

What was that at the end with the logs

Music by Kitaro?

Amazing process!!!

Hmm how many katanas can that make

The method from this footage is the original way of making Katana dating back 1500s.

It'd be too much work to screen shot every section and Google translate it

お弟子さんの正座ひとつとってみても厳しく指導されているのがわかります。 全日本で優勝した剣道家でもきちんと座れない人がいるなぁ

i can't stand the cartoonish music lol

Outstanding and subbed

"Juice is carefully applied to the temper line"...what is this "juice"?

It makes me imagine that much of the sword's ability to cut has to do with the fineness of the polishing, which reduces the 'drag' as it cuts through 'an object'; somewhere, i read that, in early days, the katana was tested by cutting through a convicted criminal. It was said that a criminal, who knew this fate, would try to swallow small stones, in order to damage the sword used to execute him....strange stories, but brutal times...

Great content. I remember working on it.

Not bad, I think I helped on this one. Needs a footage fixing. With some touch-ups.

since these guys did chemical analysis of the katana steel I'm surprised there's no mention of silicon or manganese content, as nearly all modern industrial steel contains those two elements in addition to iron and carbon.

in video after video I hear that a katana is durable because it has a hard outer shell and a tough inner core, but that just doesn't make any sense, for the inner tough core to bend at all the outer shell has to also bend, which means the outer shell will crack, about all you can really say is that a crack in the outer shell will most likely only propagate to the core and the crack will stop there, the sword is still in one piece but it is definitely damaged. Also in every video I've seen the outer shell has about 3 times as much material as the inner core, so again there's so little core that I don't see how that can make a difference.

Click cc on then go to settings and click the translation to english. Your welcome.

I have some tamahagane from NBTHK back when he was in charge. They call the smelter a "Dragon" and the steel "Dragon's Egg".

This to me (an old navy Foundryman) is Magic!

Second time I've watched this and I will most likely watch it again , great content and the skills shown are getting very rare which makes me feel privileged , thanks for sharing .

Hey, just out of curiosity- are you guys an actual school or practice that specializes in tamahagane steel?

No one can match wootz steel talwar nd shamsir... bt world lost that wootz making process.. no steel is better then south indian wootz steel for sword...

These are master Alchemists.

So more biutiful video tks🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏😇

but they used that very sword that takes a million lives during the WWII.

6:23 .... may as well've used a baseball bat. I saw nothing special there. Better katanas show an instant perfect cut rather than "pushing" the object off to one side.....

Weren't the old tea kettles made from cast iron? How is it able to be forged?

Anyone who has experience in sharpening - ACTUAL FREE-HAND SHARPENING, not RaZuR sHaRp EZ kits - knows that it's anything but boring. I personally shave with a knife I sharpened myself, but it took a culmination of literal years to get to the point I am now after 20 years. Some things people may not realize by watching: - as you sharpen, you begin to feel the correct angle and even the grit seems like it's talking to you and relaying information between what the blade is telling you. You start talking to it like so, "am I pressing hard enough? Too hard? Is this angle right? I need to relax my shoulders more. Did I just feel a burr? What technique am I going to use next? Was that return stroke right? Let me do that one again."

Love it! Thank you very much.-

Interesting. Shows several steps skipped in most modern documentaries.

Olá! Ainda existe o programa?

Fascinating

浅野鍛冶屋さんじゃぁないですか

ㅠ

Katana fan metallurgist, so many. What is spring steel?

11:53 that droplet just came up.

I’ve got a 5 pack of serated knives from Asda and the bread knife is really sharp.

The beauty of the Katana is how it’s made.
