My current material on hand is 1018, A36, and 1045. So, steel would be the accurate answer. What I want to forge out of it is open, right now I want to learn because I don't know. My question was driven towards learning the fundamentals that can be used in blacksmithing in general. I would like to learn eventually to make my own smithing tools and at some future date to harden and temper steels for woodworking. For now I am looking to the very beginning projects, think what you would hand someone walking into your forge never having seen an anvil, what would you teach them first. I know what I would teach an aspiring machinist first (care for your tools), but I am asking you folks what you would teach first. Come to my machine shop and after 20 years I know the things I would teach you first because they are the foundations of learning the skill of machining.
