Hello, I am relatively new in knife making, and I have only used mystery steels and salvaged steel. I plan on making a big survival knife that I can use for cutting and chopping. I managed to find steel from a big blade that was used for cutting paper sheets in stacks. The problem is that it is around 6,5 mm thick. Is it okay for a knife or is it too thick??
I also have 1.5 mm thick sheets of steel that were used as blades for cutting tobacco in the cigarette factory in my town. Currently they are over 62 HRC, but I am afraid to anneal them because I don't know if I would be able to heat treat them without warping due to them being so thin. Should I work with them as they are, with a lot of cooling down, or can I anneal them first??
