So in Gassan Style, it doesn't need to add Carbon after heating the material right? How about the carbon grade in the finishing material? Still 1.3-1.4?
That's not the case. A check of the C content at the beginning of the process is needed. I used high carbon oroshigane. According to the sparks on the belt sander, there is about 1.3%C. Tamahagane is about 1.1%. That is sufficient. It is necessary to reduce the C content to 0.6-0.7%. Therefore, no ashes. This would slow down the process of reducing the C content. Significant jigane is also due to the mixing of the material. It can be different. If you want a more koto look, you need to use more oroshigane. But you don't have to mix either. Then it's more difficult to show..... hard work for the polisher. Gassan is a long tradition. Gassan koto swords look different. Other than gendai. Significant difference in hagane steel. That means they are san mai and na hagane is high carbon oroshigane. Not a mix. That's just on the sides of the blade. There, steel is used with large differences in color and C content. Kobuse style is not common for the Koto period in my opinion. Sleeping hon san mai. So it depends what period, style you are producing. And on the selection of steel at the beginning of the process. Adjust the entire process accordingly. Including hardening. Or jigane formation. They are small differences. It is difficult to detect them. Everything looks the same. But it's not.
Oh, that's amazing! My size of job (I make tantos and ko-tantos) but x1000 craftsmanship and expertise 👍 These lines are superb!
