Sorry no help and OT, but I once lent a couple of my friends some old school pipe wrenches that were my dad's. One came back bent. Not just a little bent either. Must have put a cheater bar on it or something. I never really asked and they never really fessed up. Who does that? (Borrowing a tool and returning it broken, I get the using the cheater bar part). Also I always wondered how they managed to bend it and not snap it. Must be aluminum like you mentioned, I guess I assumed they were cast iron. I'll post up a pic tomorrow. Still keep it around to remind myself not to lend tools to friends, LOL...
