A hammer handle is made of a spring strip formed into an oblong closed figure and a synthetic resin handle body molded around the frame. The closed figure is interrupted at one point along the front longitudinal side. Abutment of the free ends at the discontinuity prevents the frame and thus the handle from flexing in one direction when the hammer claw is used, but the free ends part to permit the handle to flex in the other direction and thereby reduce the shock resulting from striking a workpiece.

An impact tool handle comprising: a. an elongated frame member of resiliently deflectable material defining a substantially closed figure in a plane defined by the longitudinal axis of the handle and the direction of the impacts to be transmitted by the associated impact tool head to be affixed to one end of the handle, said frame member being discontinuous at one point along one longitudinal side thereof, the portions of said frame member at said discontinuity being closely spaced in the rest position of said frame member and abutting in one direction of flexure of said frame member in the plane defined by the closed figure to substantially limit flexure in that direction and being movable relative to each other in the other direction of flexure thereof in said plane to permit such flexure, said portions of said frame at said discontinuity normally being disposed in said rest position and being biased into said rest position after flexure in said other direction of flexure; and b. a flexible handle body substantially encasing said frame, said portions of said frame member at said discontinuity being relatively movable in said handle body, flexure of said flexible handle body and frame member concurrently occurring in said other direction of flexure, but flexure of said handle body in said one direction being substantially limited by said frame member.
