Abstract
A lightweight, hand-held portable tool for opening a smokeless tobacco container uses a rotatable cutting wheel to slit an adhesive coated paper wrapper extending around the rim of the lid and cylindrical body of the container. The tool has a top member which rests on the circular lid to fix the position of the cutting wheel at a distance therebelow. The cutting wheel is recessed in a body member perpendicularly disposed to the top member to restrict the cutting depth to the combined thickness of the rim and wrapper. The tool includes grasping surfaces for the user and a guide member shaped to conform to the side surface of the container so that the opening operation can be accomplished by revolving the tool about the body of the container as the top member rests on the lid.
