Whether you are a gearhead or a computer repair monkey, dealing with small metal parts is inevitable. The Magnogrip is a powerful, wrist strap that can hold all things metal with the help of magnetism. It may not hold a sandwich (unless you enjoy an aluminum hogie), but the Magnogrip will make sure you never lose a screw, nail, bolt or nut again. $15.
