Step 10Grind or file to shape
QUICK passes on the grinder, only a second or two to do the whole edge. To long in one spot and you will heat the metal up to much and ruin the temper-take to much of the hardness out and it will never keep an edge.
I started by grinding the bump off the back (coarse grit wheel) and evening out the cutting edge (fine grit wheel). If your grinder has a grinding wheel and a wire brush, then just do what you can. After the rough shaping, I sharpened the blade. Keep dipping the blade in a bucket of water, it will help keep the metal cool. when you can see that the water has evaporated, dip it again.
