I cannot understand why the steel for the making of the Tsuba was folded during forging.... the Japanese never did that.. straight iron was mainly used.
And where would they get homogeneous steel? No material other than laminated steel was available. It was the same in Japan and in Europe. Try studying old steel objects on historic buildings. Everything is folding. There was no other option. Except cast iron. But it is not a suitable material for a tsuba. It's fragile. Your information is wrong. Fold lines are visible on many old tsuba. (Tekotsu). Especially on the edges.
There was no monolithic steel made in Japan before the introduction of the blast furnace. All steel or iron was made in tatara, which meant steel sponge that needed to be forged into a form. As a result even the nominally wrought iron - which is nothing like European wrought iron - was folded and forged down into a voidless geometry. The visible presence of the grain in steel swords was from the presence of decarburised welds relative to the microstructure of the core of grains during the kitae process from the selected small broken tiles of shingane and kawagane. In mostly decarburised steel, very mild or essentially pure iron used for tsuba, there's no such visbility without a powerful etchant, if at all.
Спасибо что показали как делается бурт,всегда было интересно
Oque é o material que fica derretido pra prender o tsuba
Asfalto, cera de abelha, lacre
Looks good. Looks really good.
Where did you learn to making engraving chisels like that? I’ve tried but never succeeded
Thanks
I didn't learn it anywhere. I tried. It works.
