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 invention claimed is: 1. A hand tool comprising: a thermoplastic plastic handle having a distal end, a proximate end and a grip portion disposed between the proximate end and the distal end, said grip portion comprising first surfaces and second surfaces, said handle further comprising a longitudinally extending through bore having a centerline, said through bore extends from the proximate end to the distal end, and said through bore is free of thermoplastic material; said through bore comprises a rectilinear cross-section, and said tool comprises a pry bar, said through bore rectilinear cross-section having a first cross dimension; a metal impact cap disposed within said bore at the handle proximate end, said metal impact cap comprising a proximate end and a distal end; and a blade having a proximate end and a distal end, said blade proximate end being fixedly disposed in said through bore at the handle distal end; said blade distal end being formed with an acutely angled blade edge, said blade edge being spatially disposed from said centerline so as to provide an off centerline working edge; said blade having a rectilinear cross-section, said through bore extends through the grip portion of the handle to fixedly receive the blade, said through bore proximate end portion comprising a portion having a second cross dimension, and the metal end cap is fixedly disposed in the through bore second portion; said second cross dimension being less than said first cross dimension, and wherein said blade proximate end is in facing disposition and immediately juxtaposed to said metal impact cap distal end; said grip portion first surfaces being planar and said grip portion second surfaces being curvilinear, and further comprising elastomeric material fixedly disposed only on the curvilinear surfaces and said planar surfaces being free of said elastomeric material; whereby the grip portion elastomeric material curvilinear second surfaces in combination with the thermoplastic material planar first surfaces provide ergonomic grip and permit effective leverage force to be exerted on the pry bar blade edge. 2. The hand tool of claim 1, where wherein a cross-section of the grip portion comprises an irregular octagonal section comprising four straight lines comprising said first surfaces and four curvilinear lines comprising said second surfaces and said curvilinear lines being longer than said straight lines. 3. The hand tool of claim 1, said elastomeric material comprises holes. 4. The hand tool of claim 2, said blade rectilinear cross-section being disposed in the grip portion so that the blade rectilinear corners are facingly disposed to the curvilinear lines. 5. The hand tool of claim 1, said grip portion comprises four first surfaces and form second surfaces in alternate disposition, wherein each elastomeric material curvilinear surface is disposed between two thermoplastic planar surfaces. 6. the hand tool of claim 5, said elastorneric material comprises holes. 7. The hand tool of claim 1, said through bore comprises a step disposed between the impact cap distal end and the pry bar blade proximate end. 8. A hand tool comprising: a thermoplastic plastic handle having a distal end, a proximate end and a grip portion disposed between the proximate end and the distal end, said grip portion comprising first surfaces and second surfaces, said handle further comprising a longitudinally extending through bore having a centerline, said through bore extends from the proximate end to the distal end, and said through bore is free of thermoplastic material; said through bore comprises a rectilinear cross-section, and said tool comprises a pry bar, said through bore rectilinear cross-section having a first cross dimension; a metal impact cap disposed within said bore at the handle proximate end, said metal impact cap comprising a proximate end and a distal end; and a blade having a proximate end and a distal end, said blade proximate end being fixedly disposed in said through bore at the handle distal end; said blade distal end being formed with an acutely angled blade edge, said blade edge being spatially disposed from said centerline so as to provide an off centerline working edge; said blade having a rectilinear cross-section, said through bore extends through the grip portion of the handle to fixedly receive the blade, said through bore proximate end portion comprising a portion having a second cross dimension, and the metal end cap is fixedly disposed in the through bore second portion; said second cross dimension being less than said first cross dimension, and wherein said blade proximate end is in facing disposition and immediately juxtaposed to said metal impact cap distal end; said grip portion first surfaces being planar and said grip portion second surfaces being curvilinear, and further comprising elastomeric material fixedly disposed only on the curvilinear surfaces and said planar surfaces being free of said elastomeric material and wherein; a cross-section of the grip portion comprises an irregular octagonal section comprising four straight lines comprising said first surfaces and four curvilinear lines comprising said second surfaces, said curvilinear lines being longer than said straight lines; whereby the grip portion elastomeric material longer curvilinear second surfaces in combination with the thermoplastic material shorter planar first surfaces provide an ergonomic grip and permit effective leverage force to be exerted on the pry bar blade edge. 9. The hand tool of claim 8, said grip portion comprises four first surfaces and form second surfaces in alternate disposition, wherein each elastomeric material curvilinear surface is disposed between two thermoplastic planar surfaces. 10. The hand tool of claim 8, all said first surfaces being free of said elastomeric material.
