Abstract
Production hand tool equipped with pistol grip type handle for manipulating the tool at a comfortable angle including pivotal means for adjusting the angular relation of the handle in the central plane of the tool in order to optimize hand comfort in operation and relieve muscular fatigue incident to operating the tool over protracted periods at a constant angle. A male and female toroidal segment connection establishes a virtual transverse pivotal axis with handle rigidly secured by an internal clamp having cylindrical segment area bearing contact on an interior hollow connection end of the handle.
