ABSTRACT:
A hand tool for treating the outside surface of a cylindrical component such as a pipe or tube grips the outside surface and can be rotated by inserting a finger into a finger engagement and spinning the tool about the component. Plumbers and the like clean the outside surface of pipes by using abrasive cloth, and the hand tool provides a tool for treating the surface with less effort. The hand tool has a lower body with a pivot adjacent one end and a treatment surface adjacent the other end, the lower body has a finger engagement adjacent the one end to rotate the tool about the component. A top body has a spring to join the lower body allowing the top body to pivot, and has a guide position to guide the component in contact with the treatment surface, the spring applies a force between the component and the treatment surface as the tool is rotated.
