This combination tool has a fold-out blade, a fold-out corkscrew, a cleaning brush, and a can opener of the type where a spur is pushed into the center of the area to be cut, and then a stub blade cuts a ragged circular cut. In this opener, the blade is set in from a roller that would ride on the outside of the can, so that the cut stays next to the can rim. The blade and roller are set on a sliding block that is drawn toward toward the stabbing spur by a spring.

Improved by patent no. 327,983.
