Abstract

An improved tool handle for a resulting tool is configured to be of an ergonomic cross section, such as a rounded triangle or a teardrop. The improved tool handle may include a core of glass strands within a plastic binder, as well as a coating formed over the core that resists penetration of glass strands therethrough. The coating of such a tool handle may be formed of two separate materials of two durometer hardness in order to provide both a relatively hard grip region and a relatively soft grip region that are contiguous. Such a tool handle may additionally include texturing such as knurling on the harder grip region.
