I was doing some cardboard and wood cutting tests with two folders I just made and had my suspicions confirmed that they did not heat treat properly. There was a hidden tang fixed blade and another folder I already sold in that batch, so I'll be contacting the customer to explain what happened and ask if I can bring it in for testing. I guess that's what I get for not listening to you guys and doing O1 in a forge 
Luckily for me, I just got access to a lab at university that's basically open access 24/7 with 3 heat treating ovens and at least as many hardness testers, so making sure it hardens properly next time will not be an issue. I'm thinking of using anti scale compound, and checking hardness every step of the way (like I already should, if I had access to the equipment before). What other precautions do I need to take? Should I blunt the edges down to 0.010" or thicker? I'd hate to lose more edge to warping. Since three out of four of the blades are folders, I would really like to have to do as little refinishing as possible, to keep the tolerances from going out of whack. I will completely redo the blades if need be, but I'd rather it not come to that.
