Abstract: An improved bowler's tape tool includes a curved tool portion with an enlarged handle portion. A knife edge is formed at one end of the curved tool portion. The knife edge is smaller than the curved tool in both radial thickness and circumferential extent. The knife edge can be placed behind the tape in a bowler's thumb hole for removal of the tape. The curved tool is utilized to apply new tape within the thumb hole. The handle facilitates easy gripping and movement of the tool to either apply or remove the tape. In other aspects of this invention, the handle portion extends radially outwardly for a greater distance then the curved tool portion. This ensures that the user is able to properly control the curved tool portion and apply the required forces for application or removal of the tape. Further, the curved tool portion is preferably formed with a radius of curvature that is smaller than the radius of curvature of the thumb hole such that the tool can be easily moved within the thumb hole.
