    im planning to make a couple knives out of m390, from the group buy. I’m thinking the heat treat for wear resistance using sub-zero (I have cryo) with high temper is what I’ll use, endless I’m told something else here. What are you guys using, and what do you recommend?

    I harden @ 2140 with a 10 min. soak, plate quench, LN overnight, & temper @ 350. This gives me ~62 RC and excellent performance.
