About 6 months ago I was at work carrying a large pnumatic grease barrel pump (picture long and skinny about the size of a mounted machine gun and about 100#) up three flights of stairs, I stoped at the top of the stairs to take a breather and rested the part that goes in the barrel on a hand rail while the other end was on my shoulder. the darn thing slipped off the handrail and the 2" round end went straight down on the top of my foot. Luckily we wear metatarsal safety boots at work the pump hit with enough force to break the plastic metatarsal gaurd and make my foot black and blue for a week, but I may have lost it without them. I never buy boots without steel toes but I am concidering metatarsals for my shop boots after the grease pump incident. It only takes a second for an accident to cause a lot of pain. I imagine toes come off as easy as fingers do (your fingers will come off really easily don't ask me how I know) and it can be totally avoided with proper boots, cribbing, clamping, and safety procedures
