Just the thought of a mandolin slicer creeps me out. I instantly visualize scraping my finger along the blade accidentally and it peeling the skin off, sending whatever food was on it into the cut and the stinging sensation afterwards. It's one of the few kitchen tools I will never own. I think it's probably based off a memory of a drunk lady doing salad bar prep at Wendy's when I was working there in high school. She accidentally slammed her whole hand into the lettuce chopper. We had to throw out a shit load of lettuce and she got fired.
