When you're cutting, make sure no one is within arm's reach of you. Keep your hands and fingers away from the blade, hold the orange firmly so it can't slip, and cut away from your body. Always use a clean, sharp knife, and store the knife away properly when you're not using it, even if you're just setting it down. If you have one, you can even wear a Kevlar glove on your non-cutting hand to help prevent accidents.
