Not me, but a friend of mine was using a circular saw about 2 months ago and the saw kicked and cut the bottom of his stomach skin right above his groin and his stomach and intestines fell out. He's doing fine now, everything went well. Me, I cut my hands a lot. Cut the tip of my pointer finger off, in front of the nail. Then about a month later I cut my ring finger on the inside down to the bone about 2 inches long. Both on my right hand. Needless to say I now wear safety gloves. West Chester's that are for people who work with windows and a lot of glass. They were about $20 and worth it. Mechanix Gloves don't hold up like I thought they would.
