Support BladeForums! Paid memberships don't see ads! First time! I have recently become interested in forging, I am building a forge and an induction heater. In the meantime the suspense of wanting to build an axe was killing me! So I cut one out of some 4140 AR plate that has a specia hearl treat and mixture on it. 1. I designed it and cut it cold on my water jet . 2 . I actually cut the vertical bevel on the waterjet as well. 3. I cleaned it , wet sanded it smooth and then I carefully filed the curve on the blade. Any thoughts on what I should do next ? Any advice on heat treatment? Will it work ?
