A can opener includes an operating rotary handle body incorporating a rotary serrated clamping head to clamp a projecting edge joint of a can against a cutting disc. The clamping head is mounted on an eccentric shaft which is driven by a central shaft of the handle body through gears in which the driven gear incorporates a means for moving axially the clamping head to a clamping position. Upon rotation of the handle body, the clamping head clamps a projecting edge joint of a can against the cutting disc, and the cutting disc severs the edge joint.
