I have a few other lost digit stories, Phil reminded me of guy I worked with that held plywood up and proceeded to cut across his fingers. That guy hurt himself every day, we used to bet on the time.
Another was when I was a kid , my grandfather took me to a saw mill and the owner was explaining how he had cut 2 fingers off and in doing so cut 2 more off. I remember how calm he was and all he said was d amn it, I did it again.
Neither one was as smart as their tools.
