1)I normalize three times then soak in vermiculite.
2) Do the profile grinds
3) Heat the edge to non magnetic
4) Quench in oil
5) Temper at @425F in an oven three times for one hour letting it cool to room temp between heats
Some guys are freezing the blade between the quench and the temper in a freezer. I havent ever dont that but who know??
