I do know that it depends on the steel and what you're trying to do to it. Beyond that, I'm ignorant. I can shape a horseshoe on an anvil, but that doesn't make me a blacksmith, or anyone other than someone who was taught one 'apprentice' thing beyond pulling the bellows
Hoping to see how this unfolds. My wife is trying to have a friend of ours who makes Japanese Swords make me a custom blade. I think it would be awesome but at the same time a lot of work. He seems to think it would be a fun project.... We shall see.
