Abstract: A can opener for opening cans of various sizes having an operating handle, which when rotated in a first direction functions to bring a sharpened cutting wheel of the can opener from an elevated position into piercing engagement with the top of the can with the butting wheel n piercing engagement with the top of the can, continued rotation of the handle will cause rotation of the can and will cause the cutter wheel to cleanly cut the top of the can so that the top can be easily removed. Reverse rotation of the handle will cause the cutting wheel to disengage from the top of the can and to return to its elevated, starting position.
