There is no doubt that Japanese craftsmen are the most important in the world in this regard in dealing with steel and knives, and my question is what is the green solution in which the knives are placed while working on them, and thank you
@@user-lk2nh1wb9c Why not? It's just anti-rust. They are used in our car radiators so that the water won't cause the steel doesn't rust. Same principle here since they are dealing with carbon steel knives that rust easily.
