I cut myself so often people think I'm one of those depressing emo kids. Only three times with an edge tool...wiping off a plane iron while sharpening, and a light one with a chisel, the third came from the SIDE of a chisel. One of the worst cuts came after feeling the edge of a freshly jointed board, I guess that corner was pretty acute! For some reason, most of my cuts are from things that you wouldn't expect.
