What is something you had in one of your pockets that injured you?

A razor. I cut a quarter or maybe an eighth(I forget) of my fingertip off just 2 days ago and it only stopped bleeding a couple of hours ago. Yes, the bleeding has stopped several times since, but only recently stopped completely. Don't ask why the DAMN razor was in my pocket, to begin with. I can't remember why. I'm going to miss that part of my finger. I'm a friggen lefty for CHRIST'S sake and that is where the injury occurred. This post was edited by Zack at October 22, 2021 9:54 AM MDT

A knife (blade up). 

I was picking my garden and without thinking put the knife in  my back pants pockets - blade up.  A few moments later I reached to get the knife and slammed my hand down on the blade.  Made a ice scar, but I also have no feeling on the back of my right hand.

My keys. A hole in the pocket and the phone key jabbed me in the thigh.

I got a chemical burn from a leaky Zippo lighter.

A steel whistle, aka police whistle.  It was in my pant pocket and I tripped and fell against the wall.  That whistle imprint was in my hip for days and all around it was black. 

I wasn't injured by it ... but I once had a screwdriver in my back jeans pocket, handle down, when a friend jumped on my back.
His leg was impaled by the screwdriver, and the muscle tightened around it so he had to go to the hospital to have it removed.
