Shooter is dead on correct.
I once made a razor out of an old hand file. I never annealed it. Must of been in the 60's Rockwell. Not only did it take a lifetime to grind, I was always sweating bullets trying to keep the bloody thing from burning up, and loose temper. Especially when I was getting close to the finished thickness. I could barely keep up keeping it cool, and thats with having a coolant flooding system hosing it down .
