I once crashed and ended up with the handle behind me, through my armpit, on the way through it hit the inside of my elbow so hard I thought it was shattered. Fortunately a week of rest and ice and it was ok but scared the living #$%& out of me. It was at 28 off and I pretty much run that in my sleep, today it's my opener. I've used handle guards since before then but don't see very many others with them, individual choice I guess.
