asi jste myslel ,,zakalit". Nicméně, po tom by bylo prd. Guláš má příliš vysokou hustotu, napekl by se na čepel a díky příliš pomalému odvodu tepla by k zakalení nedošlo. Takže bych zprasil guláš i čepel.

Czech Republic. It is capacity limited. Just for a few friends.

@@katanamaking2606 Is it possible to come over and learn from you? :-) Have you been to Japan to learn the craft?

@@musikjunx I have been to Japan 7 times to study old swords. But I learned the craft myself. Today I think it was good. I am not currently accepting students. A paid seminar is possible. I'll make a sword, you can watch. And ask anything.

@@katanamaking2606 Sounds great. How can I contact you?

To není zdání, čistá pravda :D

A lot of "too specific" information cannot be given. For example, the exact dimensions of the furnace. Two different furnaces are used in the video. The result is different for the same amount of iron sand and charcoal used. But also every melt is different. A small difference in the amount of air will greatly affect result. It takes experience. If you want to be successful, learn to observe the details. You want the size of the furnace.... count the number of bricks in a row and in a column. All the important information is in the videos. I want it there. But for many important details you have to walk a long way. On your own two feet. They cannot be shared. Not because they are secret or because I don't want to. It is the same as learning to swim. I can describe it to you, but many skills can only be acquired through practice. By creating the ability to perceive details, the environment, the sounds. And learn to react to them, to improvise. Because the conditions change during the tamahagane making process. You have to listen to the sound of the tartar, watch the color of the flames. It's not easy. Thanks to repetition, practice, you develop intuition. Ability to respond. It's the same when making blades. ("You need to think about it and constantly repeat it in practice."
