I used 02 steel for the last knife blade I made. I'm curious how you heat treated your blade. I carefully heated the edge of the blade cherry red with a torch leaving the back of the blade untouched, then quenched in motor oil. Instead of drawing the temper after quenching I left it hard as sin, while the back of the blade remains soft. The goal was to have an edge holding cutting surface while having the balance of the blade be soft to keep it from snapping/breaking. It seems to work, as it holds an edge like nobody's business. I'm wondering if I didn't commit a knifemaking no-no!
