States of the Piranha
- At Rest – The movable blade guard is locked over the blade
- Prior to Attack – Box pushes the button down releasing the lock on the cover
- On Attack – As the knife is pulled along the box, the movable guard rotates out of the way exposing the blade.
- During Attack – Once the blade starts cutting the movable guard is held in position by the box and the lock is held in the open position until it is removed from the box.
- After Attack – Eventually the teeth will get dull. Luckily there is a handy storage bay for 5 spare blades!
