A can to be opened is placed on the wheel at its upper projecting edge, and rotated by the wheel as operated by the motor. During rotation the top of can is cut by the cutter. For usual use, the opener support can be placed on the upper surface of an object such as a kitchen table with its bottom in contact with the upper surface. For use in suspension, the support can be secured to the lower surface of a fixed object such as a hanged sideboard by installing its bottom to the lower surface. For usual use, the base of the support is located below the opener body. For use in suspension, the base of the support is located above the body.
