ABSTRACT:
An impact tool, such as a hammer, having a head with a tapered eye therethrough, is attached to a handle by means of longitudinal notches extending from the end of the handle inserted into the eye, the notches having longitudinal surfaces which diverge to match the taper of the eye and receiving inserts which fill the notches and the space between the longitudinal notch surfaces and the corresponding taper-forming side surfaces of the eye. Shock absorption is provided by elastomeric material filling the voids between the handle and the head of the tool.
