Abstract: An impact tool such as a hammer is provided with a metallic tool head having a handle-receiving eye in which a portion of the eye spaced from the entrance end increases in cross section toward the exit end and is also provided with a non-metallic handle having an end portion within the eye dimensioned to form a tight fit with the entrance end of the eye but having a clearance between it and the portion of the eye which increases in cross section, said end portion in addition having a peripheral indentation or recess in its outer surface, and a tough, hard and rigid molded plastic, preferably glass-filled, in the space between the end portion of the handle and the eye interlocking with the handle and having wedging engagement with the portion of the eye of increasing cross section thus effectively locking the parts against looseness and separation.

Abstract: A connection between a hammer head and a handle resting in the eye of the head but free of direct contact therewith to provide an annular space extending fully around the handle includes a pre-formed annular trim collar at the entrance end of the eye, a pair of non-crushable metal fillers traversing the axis of percussion of the tool head and an impact resistant resin bonding the assembly together. The collar is comprised of an exposed trim portion and a concealed plug portion having substantially the same cross-sectional dimensions as the annular space. The plug portion is disposed within the annular space by a force fit connection to effectively seal the entrance end of the eye and a tapered exterior trim surface extending from the shoulder toward the handle.
