Most of these are way worse than mine as far as blood goes, but mine was a real pain in the arse. I sliced the tip of my dominant (right) thumb opening my Mini-Dozier when my thumb slipped off the stud and I missed it going back for it. About 3/4 inch long and fairly deep, straight down. The location meant I had problems opening or closing any folder for almost a month without it hurting like hell.
