Abstract: Disclosed is a safe and reliable method and apparatus for opening cylindrical metallic containers which cuts into the side of the cylindrical body of the can below the upper annular rim. The device of the present invention employs a specially adapted, angularly-positioned, tapered rotatable blade for performing the cutting operation. The use of a rotatable blade results in a clean non-jagged cut around the circumference of the container. The use of a rotatable, tapered blade to cut below the annular rim or seam of the container results in an inwardly-bent edge on the newly-cut lid having no sharp edges. This facilitates easy and worry free removal of the lid. In use, a can is placed in the device such that the knurled edge of an upper disc rests upon the top of the can. The rotatable side cutting blade is then moved such that it pierces the side of the can, just below the lip seal. The side cutting blade is locked into place, and the upper disc is rotated, thereby rotating the can.
