This is my first post...anyway.
I'm restoring a old axe head for a friend the blade is going to need alot of grinding to get the pitch of the blade right. Iv heard that that will make the edge prone to chipping if not heat treated properly after. The butt of the axe is horably mushroomed but I want to use the mushrooming to make a good hammer head. I don't know how to heat treat it to get a good solid edge aswell as a sturdy hammer head on the other side? Any advise, comments or questions would be much appreciated!
