One of the bloodiest calls we ever ran in my FD days was a knife fight between guy and girl friend. Both were cut up but she lost the fight that day PermanentlyI lived with a girl who tried to stab me with a butcher knife. I do not like knives. About the closest I've come to actually being killed but I had fast reflexes and grabbed her wrist in mid strike, point about an inch from my sternum.
Seeing this, if she was still alive, I'd buy it for her for Chrimuff.
