Yes Thomas Powers, I did search before asking, I just wasn't sure of anywhere where I could get it because I think most fast food would have special things that would prevent me from doing it like deals with recycling companies. I have a bucket I was going to use, but wasn't sure if a plastic one would be safe to use.
And Frazer, I am talking about Hardening it and then tempering it back, and I know that many people use ovens and that was my plan.
