I had a friend in highschool who’s dad had lost part of his pointer finger to an encounter with a saw blade. He had just a little bit of the bone beyond the second knuckle that was weirdly pointed and it hurt like hell when he jabbed you with it. I know this because I used to help them build shit around their farm and if he caught us being unsafe he’d poke us in the chest with that damn half-finger while he yelled at us about it.

Those lessons really stuck too.
