Seriously, the worst cut I have had has been when cutting a loaf of bread with the wrong knife. It was a fresh loaf as well. Cut half into one finger tip and a sliced a piece off the tip of another. It just takes one moment of frustrated bread-doesn't-cut-wrangling and a slip.
My lesson from it: buy a serrated bread knife instead of trying to make do with whatever is in the at the time super minimal kitchen drawer. Saw the bread instead of trying to cut it.
To be honest, I would have laughed at the thought of cutting myself whilst cutting bread of all things as well before it happened.
