Yikes! I did a really dumb move years ago with a #7 steel crochet hook. Tried to put on one of those rubber sleeves to make it easiet to grip and pushed it against my thumb with a wad of paper towels under it. You guessed it, went right through the towels and all the way through my thumb. Had to go have them cut it off to get it out. Felt really stupid sitting in the ER with a crochet hook sticking out of my thumb. Too bad it wasn't Halloween. I'm glad you weren't hurt too bad.
