I was struck at how casually Adam Savage handled his table saw (and other tools) when I was watching a little web short of his on making a gun case. It was actually pretty frightening at the same time as it was impressive. I certainly take a lot more time setting things up, and my saw gets turned off the instant I'm done cutting the piece. That said, I still do stupid things (see half of this thread), but I try very hard to be safe with my fingers.
I didn't do it, no one saw me, you can't prove anything.
