Comes in side, end or diagonal types. Side cutters have a cutting blade on one side only and are available in long-, curved- and short-nose types. End cutting nippers have cutting blades on the end and are used to make sharp, clean cuts close to the surface on wires, bolts and rivets.  Diagonal cutters have two cutting blades set diagonally to the handle. They offer leverage when pulling cotter pins and are used by mechanics and electricians for general cutting.
