Sorry to say buddy but your info is wrong pure iron melts at 1500 degrees Celsius. And tamahagane is pretty much pure iron. Therefore they smelt at around 1,458 to 1,485 degrees Celsius so it will have as little impurities as possible. So by all means it’s not smelted and created at low temperatures by any means

Long live Yoshihara san.

32:12, uh oh, gotta start over.

There are many documentaries about japanese swords, but I find this one the most enjoyable by far.

Coming back to this docu for my yearly rewatch. Im always struck by the technique of placing the raw steel directly into the charcoal while forging. Im guessing this is necessary to get the metal up to proper temps, but i find it strange the forge isnt set up to keep the fuel separated from the steel. Several times during the early parts of the process you can see the smith having to knock ashes and charcoal bits off before hammering. Im just a layman, but it seems to make the whole forging and foundation process a bit more rough. Doesnt all the direct contact with the fuel exacerbate the process of ridding impurities...as well as making it harder to observe the condition of the metal while in the forge?

Who is here after blue eyed samurai?

Form my frame of reference, this is the closest thing to actual “magic” we will ever see!

Thanks🙏

When i was a kid i thought they folded the steel 1000 times individually so to speak. Its more like 2 to the power of 10. Which makes more sense. Nevertheless my ignorance makes this no less interesting. This is beauty of the highest order.

Kinda cool.. at 8:25, when a quenches the hammer in water, the first strike after dunking it is a little more energetic than following hits because the water on the hammer is instantly turning to steam (when water is flash boiled to steam, it grows in volume by about 600%) which is causing sort of a little explosion.. you can hear a pop, and visibly see the hammer energetically fly up, and a bunch of rapidly expanding steam on the first hit lol

Thank you for this very informative video. Arigato!

Yoshinhara is now 80 and gave me a samarai sword for free. He is a legend.

Also Geheimnisse fand ich hier keine. Alles nachlesbar in seinem Buch 😮

俺なら最後の仕上げはコンパウンドでやっちゃうかも

😊😊 un superbe katana, et de magnifiques, images 😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊😊

This video, is the best in tube ! His tehnique are much more ancient than everyone else.

Wondering about the price? So was I so I Googled his name and found his website. He's not taking orders for swords, but is selling short swords (actually more like knives) or 'SMALL KATANA'. The price is range from 9 to $15,000. I would imagine swords are three times that much.

wunderbares video aber ich hasse die amerikaniche sprache ich möchte sie nicht hören

This is how videos should be made. The only complaint I have, it's way to short. For my behalf the video could easily last several hours. I have a past the metal industry and I am deeply impressed, how the old masters figured out the perfection of making a katana .

The one riveting question... How did the swordsmiths learn of all this metallurgy and technique over 1000 years ago??

$65k is alot of money , but if im honest with myself if i had $60k i would Definitely buy one of these Swords

I'd love to own a sword just as exquisite. how can I buy one of his swords

Jihada = Damascas?

Sometimes it could take up to 6 months just to make 1 of these Kendo.

The amount of pride that goes into the Sword is great ,,,Now I can see why they cost so much many hours of grafting and Labor and love it’s amazing truly good to watch and learn cheers from Australia 🙏❤️💪😁🦘🇦🇺🇯🇵🥷🥷

Only one word : Excellent .

The " big clove blossom " Hamon technique looks like spread out bolts of lightning during a heavy thunderstorm.

Why is there so much Only in Japan? "Japan is a superorganism" go2senkyo.com/seijika/165194/posts/824886

I would hate to think what that masterpiece is worth. Great video 👍🥃🇦🇺

How is the connection of the tamahagane and the steel rod called? Tekugane?

S a very well corriographed video. Great smithy

Theres something beautiful about how the Japanese rejects technological advances and remains true to tradition. This is something you can't find in America. America destroys traditions with innovation.

Beautiful!❤

Without a doubt the best Japanese Sword forging video I have ever watched. I will share it with others. Thank you very much⚒️⚔️

Gorgeous hamon, nice utsuri, one can get lost in its reflection, for hours.

His book is awesome arigato.

Left out the sharpening

I love how he started the fire tradition

One of the most beautiful items created by hand, in All history of mankind. 💜.

Excellent documentary! Thanks!

Perfect weapon for a Klingon warrior!

相手が、刀や木刀、長棒 、サスマタなどの［武器］で襲ってきた場合には、どうするんでしょうか？

There are some guys making pretty beautiful and well crafted pieces on youtube but this feels a bit like watching Michaelangelo or Da Vinci at work

Talk about following tradiction. They forged that sword without using any protective equipment to include eye wear

I know this is expensive,how much it's cost?

These sword smiths do everything so precisely like they all have OCD from choosing the raw materials to final polish and sharpening even how they hammer a piece of iron getting it hot enough to light a piece of paper to light the forge I can imagine how much money they fetch for one of those blades forged by a true master

This I such an interesting and memorising video, I've watched it a few times now as each watch teaches me a little more, I've a four day forging course booked for next year instead of a holiday, not cheap, I get to do something I've always wanted to do, learn something, I've chosen to make a Kukri as I served with a couple of Gurkha's when I was a soldier in the Royal Corps of Signals in the British army, I fell in love with the versatility of the Kukri, not for its sinister side, but it's other uses and its pure beauty, I can't wait for next May, 2024, the course falls on my birthday, I can't think of a better treat for my 58th birthday. I get to keep the Kukri, so I'm praying I do a good job, it's all down to how much attention I pay to my instructor, I know it won't be easy, it's my first time in a professional forge, apart from the basic forging in wrought iron which I did in my senior school years.

Beauty in metallurgy.

Blue Eye Samurai brought me here

Why doesn’t the smith polish it himself? It seems quite vital for patterns on the sword.
