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. |
