An improved can crusher which has a pair of pivotal arms responsive to the position of a piston within an elongated, base mounted tube for denting or creasing and piercing the side of the can prior to the crushing the can by the piston. The piston is activated with a pivotable handle which engages the piston through apertures in the tube. The pivot arms are mounted to the outside of the tube and their ends remote from the base are biased toward the axis of the tube into engagement with the side of the piston. As the piston moves towards the can, the protruding portions of the upper ends of the pivot arms are forced away from the axis of the tube thus forcing protruding portions on the lower ends of the arms into the side of the can, thereby piercing and denting the can. As the piston crushes the can, the lower protruding portion is pivoted away from the can by the action of a biasing spring. The end of the pivotal handle can be curved to reduce off-axis forces on the piston.
