ABSTRACT:
A can opener for opening cylindrical metal cans by means of a reciprocating, circular motion produced by holding the can opener in the hand of the user and moving it up and down while also rotating it about a vertical axis. The can opener includes a handle at its upper end on a hollow, cylindrical shaft which includes at its bottom end a series of, for example, four radially extending arms having at their distal ends downwardly pointed, "V" shaped blades having sharp tips, and a smaller, spring-bias shaft which telescopically fits into the main shaft and which has at its lower end a magnet. The ends of the cutting blades also preferably include inverted "U" shaped hooks which engage and hold the upper, vertically extending peripheral lip of the can during the cutting operation. The cutting blades telescopically fit into the radially extending arms, so that they can be easily removed and replaced with cutting blades that provide a different effective diameter of cutting action for different sized cans.
