How to Sharpen an Axe and Other Tools
Photo 4: Sharpen the blade with a grinder. Grind the tapered cutting edges with a grinder only if you see nicks in the blade. Follow the factory angle of the cutting edge. The grinder will remove nicks in the blade much faster than you can file them. (If you don''t have nicks, go to Photo 5.) Don''t overheat the blade!
