A pry bar has generally octagonal cross-section handle with a grip portion having four rounded surfaces formed of a soft elastomeric material and four alternating surfaces formed of hard thermoplastic material. The elastomeric material rounded surfaces are formed with pluralities of small orifices.
A pry bar has generally octagonal cross-section handle with a grip portion having four rounded surfaces formed of a soft elastomeric material and four alternating surfaces formed of hard thermoplastic material. The elastomeric material rounded surfaces are formed with pluralities of small orifices. The handle is formed with an inner hard thermoplastic core and molded over outer elastomeric cover. A metal impact cap is fixed secured in the handle proximate end.

The hand tool of claim 1, each said thermoplastic material grip surface and each said elastomeric material grip surface being about equal. 3. The hand tool of claim 1, said elastomeric material grip surfaces being formed with a plurality of orifices. 4. The hand tool of claim 1, said thumb receiving elastomeric material surfaces being formed with a plurality of orifices. 5. The hand tool of claim 1, said thumb receiving thermoplastic material surfaces alternating with said thumb receiving elastomeric material surfaces. 6. The hand tool of claim 1, wherein the elastomeric material grip surface extends from the grip portion to the handle distal end. 7. The hand tool of claim 1, wherein the thermoplastic material is harder than the elastomeric material. 8. The hand tool of claim 1, wherein the handle comprises a cylindrical cross-sectional recessed portion. 9. The hand tool of claim 1, wherein the handle recessed portion adjacent the handle distal end has an outer surface entirely covered by the elastomeric material. 10. The hand tool of claim 8, wherein each thermoplastic material grip surface extends from the handle proximate end to the recessed portion. 11. The hand tool of claim 8, said grip portion elastomeric material comprises orifices disposed at the surface, and said elastomeric material in the recessed portion being free of said orifices. 12.
