Last night I was in the final process of tempering a machete I am making for my grandson. I am using a light leaf spring for the blade. I was explaining to him the process of hardening and tempering and he asked me a question I am not sure how to answer. I did some internet searching and couldn't come up with anything definitive. The question was can you anneal steel, harden and temper it indefinitely or at some point does it become slightly "fixed" in one state and require higher heat or greater shock to work the magic? Thanks very much for any practical insight.
