I was cutting a small (1" cube) piece of wood on my table saw, from a very short piece of 2 X 4, too small to hold. Wound up slicing the edge of my left thumb.

Wrapped it up with a clean rag and drove myself to the Emergency Room.

The surgeon complimented me on making a very smooth cut on the bone. I said that's what happens with a sharp 12" carbide toothed blade..
