Left-handed scissors (the good kind) are hard to find. My daughter's a leftie, and her first grade teacher was constantly chewing me out for my daughter's tendency to take rightie scissors in her left hand and cut toward herself. But she just refused to use those ridiculous kindergarten left-handed scissors. She does mouse right-handed, though.

As for potato peelers, I believe most of them are symmetrical... when new. I always thought I should find a left-handed person to trade with, so the blades wear out evenly. <G>
