Dave, I find the bench mounted belt and disc sanders to do a nice job in cleaning up bad rust pits and applying the bevel with its desired sweep. I use what is available, if I had a large hand held grinder I would surly give it a go. I keep a dip bucket very close by. As I am holding the tool, without gloves, I can feel the heat, I want a cold feeling on the steal. I have used a squirt bottle, too. With a hand held grinder you should take extra precaution to keep the work cool.

It is interesting to see the nick lines left in hewn surfaces. They all didn't spend hours taking the nicks out of the edge. They touched up the edge and went back to work. On this one frame you could see which timbers this axe was used on, through out the frame.

Nice link to some edge cutting tool, DL.
