Hey guys, New bladesmith here. I am making some knives out of files so this is my planned heat treatment. Please critique. 1. anneal files 2. shape blade, bevel, and handle 3. re-anneal finish, formed blade (to relieve stresses formed during shaping and ginding) 4. triple normalize blade checking for flaws between each cycle. if flaws are present they will be fixed and the triple normalizing process repeated until no flaws are present through all three cycles. 5. heat to slightly over non-magnetic and quench in oil 6. temper 350 degrees f for 2 hours, 2 times with one day between cycles One other question -- if and when grain growth occurs is it reversed by annealing? what methods do you use other than preventing overheating do you use to minimize grain growth? Thanks for the help guys.
