For me it would be a toss up between my grinder and the razor knife. The grinder I have set myself on fire.....more than once and cut fingers with cut off wheels.....more than once. The razor knife, been nicked and cut several times. The worse so far has been to my wrist. I was shaving the edge of some drywall above my head when it slipped. Ended up jabbing me in the wrist at full depth. Luckily it missed all important parts and only cost me 5 stitches.
