I have to confess, I can't sharpen anything! I've screwed up chainsaw chains, chisels, planes, and knives trying to get an edge. I have seen ads for a jig that might be the answer for a dull minded guy like me. It's called the M.Power PSS. It's only $75, but while that would be cheap enough if it works like advertised, but I'd kinda like some user input before I just pull out the green. Any comments appreciated.
