Abstract
A novel device especially useful in opening a tobacco can or the like which has an outer wrapper embracing the can's sidewall and lid flange. A primary force member, curved to have the curvature of a tobacco can, has a longitudinal cutting lug on its innerface; and an outward tab connected to the primary force member provides a tab for pushing the tool circumferentially while the tool is pressed against the outer wrapper of the can, thus achieving a circumferential slit of the can's wrapper.
