When axing and sledgehammering i always bend down and straighten my arms so the trajectory of the head never is in a path towards my feet or shins.

Same with chainsawing, if the chain breaks and comes swinging the trajectory shouldn't be towards my groin or neck

Never try to cut a basketball with an axe.

If the axe bounces off it must be blunt. I’ll let someone else test though.

Dull blades are the most dangerous.

Personal experience? :)

Heh. Witnessed it, but it surely could have been me...I wasn't expecting it to happen.
