I have a question for the knife making crowd. I was given a piece of D2 bar stock several years ago and finally got around to using it. Made myself a nice little EDC/skinner with it, and when it came to the heat treat, I got confused. I see a lot of information online, and even asked on a couple of knife forum and Facebook groups. Still confused because I keep getting contradictory information. Some say air quench, some say plate quench. Some say cyo treat, others say just temper once cool enough to touch. Some say temper at 400and still others say up to 900.
My usual process for hardening my recycled steels are to heat to 1500 and quench in canola oil, then temper to 425 for an hour for two cycles.
Can anyone tell me if my usual process will yeild a usable knife that I can use reliably and hold a decent edge, or is the cryogenic process absolutely necessary for edge retention.
