I was cutting up some box-section (square-shaped hollow steel) with the hacksaw in metalwork, I was getting tired and slowed down a bit, the blade slipped out of the cut (it wasnt very deep at the time) and sliced the top of my index finger on my left hand. If I was cutting at full bore, I probably would've cut at least into the bone.
Just thought I'd share.
