I have just startedmaking knives and so far, they are all S30V or 20CV. I would like to make some hunting and skinning knives next out of A2 or some other high carbon steel and I would like them to be hot blued. I asked a friend who has a gun shop and he said most people have gotten out of blueing because of all the EPA and OSHA hassle. Does anyone have a good source for blueing? Also, any recommendations for steel types - I only do stock removal, no forging.
