Ever have your hands smashed when the drill jammed?

One day I got talking with an older man in a laundromat. Turned out he was a retired plumber. I showed him a DrillEver- he ‘got it’ right away. He showed me his bent fingers and scars on his knuckles. I was amazed! He said it happened when a Milwaukee half-inch right angle drill locked up and twisted in the hole- the drill slammed his hand up aganst a joist before it came to a stop. Years later, he still never had full use of a couple of fingers. He figured it was just his mistake; him being stupid. I wish he’d had the custom DrillEver that clamps onto that drill- it would’ve never happened! Ever know anybody with  fingers bent from a drill?
