Hey guys I just recently finished a pocket knife out of m4 and sent it to peters heat treat and got the blade hardened to 60rc and had it cyro treated. My question is the blade doesnt seem to hold an edge as good as some pocket knives I have made out of 1095 hardened to 60rc an cryo from peters heat treat. I did not get the blade hot while grinding or turn it any colors while grinding. Anybody got any guesses what I did wrong?
