There is nothing like a good wet grinder to get a cutting edge up to snuff. I use chisels a lot in my line of work, and anything short of razor sharp just won't do. For years I used diamond hones and a hand strop, but several years ago I bought a good quality wet grinder. It has a 1 1/2 x 8" 150 grit dry stone for removing nicks, and a 2 1/2 x 10" 800 grit (interchangeable with 1200 or 1500 grit) wet stone that turns at only 400 rpm. There is also a 1 1/2 x 10" leather wheel for final stropping. Edges done with this machine are so sharp that you have to be careful how you look at them lest you cut your eyeball.
