1. An iron-type golf club head, comprising:
a body member including a face defining a front ball-striking surface and a rear surface, a perimeter weight portion, a muscle portion and a hosel, wherein the face extends between a top line, a leading edge, a heel and a toe of the body member, wherein the perimeter weight portion extends rearward from the rear surface of the face and defines an upper cavity of the body member, wherein the muscle portion is an elongate portion of the body member extending from the heel to the toe of the body member and rearward from the leading edge of the face, wherein the muscle portion defines an elongate receptacle extending from the heel to the toe of the body member, wherein the receptacle only intersects an outermost surface of the golf club head and is adjacent the leading edge of the face and extends rearward from the leading edge of the face, wherein the body member constructed of a first material that includes a base element; and an elongate weight member including an elongate mass member and an elongate interface is disposed in the receptacle so that an outermost surface of the interface is flush with an outermost surface of the muscle portion, wherein the mass member and the interface are coupled at a bond surface, wherein the mass member and the interface are exposed only from a lower surface of the body member that extends rearward from the leading edge of the face, wherein the mass member is constructed of a second material that includes a base element, wherein the specific gravity of the second material is greater than the specific gravity of the first material, and wherein the interface is constructed of a third material that is an alloy of the base element of the second material. |
