A can opener for opening a can has a lid joined to a main body by a rim, in which the can is opened by cutting through an outer part of the rim joining the lid with the main body of the can, the can opener comprising a rotatably supported cutter wheel for engaging and cutting the said outer part of the rim, a rotatable drive wheel for engaging the inner part of the rim, means for gripping the rim between the cutter wheel and drive wheel so that, upon rotation of the drive wheel, the can opener orbits around the rim of the can and the cutter wheel can complete a cut around the outer part of the rim, and lever means driving a one-way clutch mechanism for rotating the drive wheel to advance the can opener around the can. |
