What is your worst accident with a tool? Mine include drilling through a plastic box and stupidly having my finger on the inside of the box just where the drill broke through. Luckily the bit just skimmed off my finger. On another occasion I was using a hedge cutter and removing about 6 feet of the top of a hedge while drawing the blade towards myself. I couldn't see the blade and nicked my thigh. Luckily it was a hedge cutter and not a chainsaw!
