That's why Haganezuka San was angry when he found Tanjiro damaged his sword.

Imagine the wear and tear being a Japanese swordsmith throughout the years would cause on the body, they deserve an epic health plan

[Drawnspy]

Wait where did the other 9 kg go?





Gone, reduce to atoms!

Did the blacksmith just make a katana in his living

[imiimo]

every collector dreams, high quality with lower price

Tamahagane is made from Ironsand, from a video I watched of one of the few traditional blacksmiths to make Tamahagane from Ironsand, they used 30kg of Ironsand and got about 7.3kg of Tamahagane (Usually they get 10kg but something went wrong), so they made a knife. I deeply enjoy watching how Japanese Blacksmiths forge Katana's and other blades, especially through traditional methods.

Tamahagane is not a pure steel ore that's why

[norelyntubongbanua]

Use hino truck high carbon steel leaf spring to cut the lost due to impurities

[Che_Guna]

Suggest some oldest katana makers in japan

[velazquezarmouries]

Well if I remember correctly if the sword wasnade of western trade steel ( nanban tetsu) or Chinese steel that sometimes made it's way into Japan the loss of steel while forging was greatly reduced because those would be usually sold already consolidated into bars with a more homogeneous carbon distribution as opposed to being bloom steel like tamahagane

[norelyntubongbanua]

Can you crush the ore putting in canister for canister weld make a Damascus steel

[gaetanodimezzo]

Super interesting ! I will remember this. So much tamahagane... Please :
Can you explain in a video how to recognise a good katana, at a microscopic field ? I mean, the structure, the size of the grains... Not the atomic level, but what are the perfects structures wanted for each part in a katana ? I have this question in mind for a long time. And I think that you are the man who will save me ! Thanks for sharing !

Is there a place for tamahagane kitchen chefs knives

[TheKaruProject]

That’s Yoshida Masaya, isn’t it?! I was there just a few days ago. Amazing coincidence

[veiledrecalcitrance]

Wait, did you say a skillful sword smith can make a katana with less materials by shortening the forging and heating times? So what your saying is a swordsmith can make a subpar katana because he lessened forging and heating so there’s more impurities which makes more meat of the blade, either I’m misunderstanding (very possible) or that doesn’t make any sense.

I live in punjab, India. I also want original Katana. Please tell where I got original katana. Please sir 🙏🏻
