ABSTRACT:
A finger-operated leverage tool has first and second lever elements with opposite ends and upper and lower elongated surfaces. A connection joins one end of each of the lever elements and holds the lever elements in a movable angular position with respect to each other. Elongated frictional surface strips of a material different than the material of the lever elements are secured to the upper surface of the first lever element and to the lower surface of the second lever element to prevent slippage of the fingers of a person operating the tool.
