I don't think this is here. If you are using chisels, knives, and other stuff that can slip, protect the hand that isn't holding the tool. So far, I've bounced knuckles off of a drill press mounted drum sander, missed and stabbed my hand with a knife (I'm not sure how I pulled that off), and I've stuck a 2mm gouge through the skin over my first knuckle on my index finger. If it would have been bigger, I would have needed more than a band-aid. All these injuries happened to my left hand because the right held the tool.
