  • Publication number: 20100115776
    Abstract: A manual can opener tool is formed of a handle, a shaft that has a proximal end secured to the handle, a piercing spear point, i.e., spade at the distal end of the shaft, and a generally triangular cutting knife that is mounted on the shaft and can be adjusted in axial position on the shaft. The tool is used by piercing the center of a can lid with the spear point, rotating the tool down so that the cutting knife pierces the can lid near the rim of the can, and then pulling or pushing the tool in a circle, using the spear point as a fulcrum, to make an arcuate cut in the lid. The tool does not require manipulating a crank, and the tool is also used to lift the lid off the can.
