Abstract
A tool handgrip includes a core having two or more spaced longitudinal ridges secured to the outer peripheral portion of the core. The longitudinal ridges each includes a thickness ranging from 1 mm to 6 mm and each includes a hardness less than that of the core. The hardness of the longitudinal ridges ranges from SHORE A 35 to 75. The longitudinal ridges each includes one or more projections extended inward of the core or each includes a step ladder shaped surface for engaging with a corresponding step ladder shaped surface of the core for solidly securing the longitudinal ridges to the core.
