    The Japanese sword is the soul of the Samurai. The crafting of this work of art - which embodies beauty, strength and tradition - has been shrouded in secrecy for more than thousand years.

    Yohindo Yoshihara is a consummate Japanese swordsmith and a very high regarded Mukansa craftman in Japan. He is also the best-known Japanes swordsmith outside of Japan.
    His masterpieces have been purchased for exhibit by the Metropolitan Museum of art in New York City and the Museum of fine Arts in Boston. He has numerous fans worldwide, including His Royal highness, king Gustav of Sweden.
    This video has been produced to appeal to all aficionados of Japanese sword around the world and is a treasure trove of sercrets to Yohindo Yoshihara's truly outstanding Japanese sword craftsmanship.

    Wait, you man I can't make one in two minutes using my iPhone and an expensive cup of Starbucks coffee? I lost interest... This spectacular craftsmanship is not a thing of the past, people still want quality and rarity. Unfortunately, very few people even understand what quality and rarity are, much less utility. Great video

    All for a nation that has very little in iron resources.
    With that said, they seem to have mastered the art of sword making.
    I think it is an overstatement saying they can see the small percentages of carbon in the steel.
    That takes spectroscopy that sees in all the light spectrum. For any metalworker that reaches 55 years of age, one begins to battle cataracts which my ophthalmologist states all people over 60 have.

    The amazing thing is that it is all done by hand, a master sword craftsman from 200 years ago or longer could walk in and not be out of place and pick up a hammer and join in working side by side with a modern day master. I would love to own one of these knowing the time, heart, and soul that went into making it and because they are works of art.

    Peccato che non si possa capire la descrizione, si intuisce che si creano zone di tempera differenziata, il risultato è la sorprendente durezza ed elasticità della Kataweb e della sua affilatura incredibile!

    This man is not a smith, he is an artist. It really defies belief than people who lived more than half a millennia ago using nothing but the most basic tools created something so magical and so beautiful that simply replicating it requires decades of practice and total devotion to this ancient art form. Truly breathtaking.

    The example of the different colored pieces of clay being melded together was a great example of all the process is done. It seemed to help make sense out of how they mix the steel together better than any example I have ever seen.

      @Awsome Guymaybe, but I was commenting on the process of making the tamahagane.
      I don't think it's so much "harder" as you say, to make as it is time consuming. And what is European Steel?

      lol not realy (in my opinion) because its so hard to make compared to euoropean steel and yet there are so many impurities that its practicly a useless metal compared to others

      They sell nihonto on ebay and nice katana typ in either word i had a buddie who ordered they wrap it up real good in foam when they deleiver it and tape so your sword does not get damaged i saw first hand,.. also check out bareblade katanas their aswell but then you have to have the other parts custom made for it ex: handle, habaki, scabbard to size. can get pricy.

    I appreciate the tradition of using the sand steel as a base but it is of such low quality ,requiring the hammering and folding. Simply starting with a billet or L6 , t10, or other modern metals would not only save an absurd amount of labor but provide a higher quality steel than can be achieved by these methods. I know this is blasphemy to a lot of youtube weirdos, but meturalogic x rays if katanas thru the millinia prove the steel to be s=above its ancient peers, but still pale in comparison to a high grade alloy commonly sold today, it’s just a fact.

    I had read a while back that the older Japanese swords were longer & I believe worn curved edge down. If I recall correctly, ~the 1,300's-1,500's they were cut down to the shorter sword style & flipped curved edge up. If this is correct, then is the 70% decrease not taken into account with these cut down swords? And was it worth cutting them down or were the older tips not made with the harder steel?
    BTW, I looked up Yoshindo, he was born in '43 just a year younger than my own father. This video must have been made in the 80's-90's. Are there any more recent ones that show him in his even greater mastery?

  • C Michael Bravo

    Back in my early 20's i.e. early 1990's I worked for Paulo Products & we quenched in large vats of oil for heat treating. Would that not help preserve some carbon content, whether in conjunction with the rice straw or not? If it would do so, then how will it affect the jihada(sp) or overall appearance of the blade compared to just using water? If it wouldn't affect the appearance then would it give the swordsmith the opportunity to heat the blade a couple extra times if need be while helping to preserve the carbon content of the blade in the final shaping?

    Now imagine how someone ordered one of these swords that took ages to craft (and unlike people believe, the quality of steel back then was so awful, those swords were crap...) and when he finally got it and had all kinds of lengthy ceremonials to receive it in his hands and was all so proud... then went to pick a fight and got stabbed into the eye by some peasant that used simple pitchfork made out of wood...

    It's a well known universal fact how that is the reason why Japanese folks invented their seppuku (or whatever you call it): They wanted to at least use their sword on someone, before someone else had time to poke them in their eye with a damn stick :'D

    True craftsmanship. Even to be able to work the metal at such cool temperatures is amazing and unlike any other smithing I have seen. The Hamon pattern reminded me of the Cherry Blossom trees. To gracefully move like the blossom and to also fall to the enemies blade in just as much graceful way is something that shows how a warrior considers death just as much as life.

    No difference at all in using a hammer or a steam press. If the pressure is regulated it has the same is affect. Just like using a match to light the fire has no effect on the finished outcome.
