Abstract
A swingable impact tool and a method of making it wherein the tool has a metal head fastened both chemically and mechanically to a handle made of a composite of materials including a pultrusion of fiberglass filaments in a matrix of polymerized thermosetting resin covered by elastomeric urethane form which protects the core member from impact loads and absorbs the transfer of shock loads to the hands of the user. Metal or plastic members are used to reinforce critical areas of the handle adjacent the head and the stem member disposed within the socket in the head.
