A can opener having a knob-shaped handle to be disposed over a can to be opened, a rotary cutting mechanism on a cutting head spaced from the handle, and a drive knob for the cutting mechanism on the side remote from the handle, the cutting head and drive knob being counterbalanced by the handle so that the center of gravity is over the can near the cutting mechanism. The handle has a flat, palm-engaging top surface, a beveled thumb-engaging surface along the upper edge near the cutting head, and a recessed side remote from the cutting head concavely tapering from the top surface to a flat lower side for engaging the top of the can near the cutting mechanism. The cutting head and drive knob are supported on the handle by parallel pins that bear on the rim of the can on opposite sides of the cutting mechanism. |
