With the Cutter Ability, Kirby is able to obtain an unlimited supply of curved blades, appearing on the cap he acquires with said Copy Ability. These blades have a boomerang effect, always returning to Kirby after being used. If these blades miss Kirby on their return path, they will keep going on behind him (a technique players like to use to him foes behind them). Kirby can even guide cutters both upwards and downwards after throwing them.
