I don't think this is really trivia, but I don't know where else to ask.
8500 people a year injure themselves with this common household item. The item is different for men and women. Everyone has several around their house. When women injure themselves they get bruises and when men injure themselves they get cuts. What is the item??? I was thinking razor, but that wasn't right!! I need to know the answer by tomorrow morning to win Usher tickets! Can you guys help me think of it??? Thanks!!

Well, did you find out what it was? I'm stumped. Searching on what injures 8500 people per year came up with fireworks and bathtub falls, neither ow which fits your description.
