Shop work day

I was pounding a ball joint knuckle with a small steel sledge, in my shorts. A fragment of the hammer the size of a rice grain remains in my shin. It could have gone somewhere more, well, tender. Would long pants have slowed or blocked the fragment?
At least I had eye protection. Brass sledge next time.
Reminds me of something
We were changing the track on a M60 Tank...A guy was swinging a sledge to drive out a pin. All of a sudden he bowls over in pain. A piece the size of a bb broke off and flew through his pants and underwear and went into his nuts
I told him drop his drawers as he was in a lot of pain. Sure enough there was a hole in his testicles and bleeding.
Took him to the hospital but when he got back to barracks we all had a good laugh over a few beers
