So my third knife is heat treated and it warped in the process. Being a new maker, I was not fully prepared for dealing with a warp so I did what I could. I sandwiched it between two steel blocks during my first temper cycle. It didn't straighten out. I bought a toaster oven today and I have rigged a C-clamp with washers and a steel bar to flex the blade in the opposite direction to the warp. I put the whole assembly back into the oven at 400f for 1 1/2 hours. Removed and it is cooling. The blade is 1095.
If this does not work, what else can I try? Or should I try a different time/temp in the same arrangement? I have heard of guys straightening cold blades but that really gives me the 'willies'.
