1. Rushing to correct a mistake in a change table project before my daughter was born. Too few shed days and a fast pregnancy (Only 37 weeks).
I was chopping the last of the mortises, and my left hand was in the tool path. Of course the freshly honed (8000 grit) heavy pig-sticker chisel found its way at high speed into my left hand. I felt it hit the bone.
2. Helping out the chippy I hired to finish off my attic. On a ladder, reflexively trying to catch a hammer (of all stupid things) that he had tossed my way. Came off the ladder, fell with my outstretched hand finding his toolbox, with his trowel point up. Tool surgically removed from my left hand.
