Abstract
A dual-handle pump-action can opener that can be operated by either hand and cuts the exterior wall of the seam of a can, rather than the top lip of the can. The dual-handle pump-action can opener includes: (a) a housing having a first handle; (b) a cutting wheel associated with the housing and the first handle and having a cutting edge for severing the exterior wall of the can seam; (c) a traction wheel associated with the housing and the first handle and having a gripping surface for engaging the interior wall of the can seam; and (d) a second handle which is movable towards and away from the first handle. When the second handle is initially moved towards the first handle after the can opener is installed on the seam of the can, it causes the traction wheel to contact the interior wall of the can seam and the cutting wheel to contact the exterior wall of the can seam. On subsequent reciprocal movement of the second handle towards and away from the first handle through a series of levers and gears, the traction wheel is caused to rotate in incremental steps to advance the traction wheel along the interior wall of the can seam, thereby causing the cutting wheel also to rotate and cut the exterior wall of the can seam.
