Abstract
An improved, iron-style golf club, which comprises a substantially perimeter weighted clubhead, including an exceptionally hard coating, which is metallurgically bonded to the front face of the clubhead. The rear face of the club comprises concentric recesses substantially co-located at the center of gravity of the clubhead. The recesses are sequentially filled with a variable amount of elastomer material, which is chemically bonded within the recesses. The elastomer acts as both a shock absorber to minimize the shock experienced when the superhard clubface impacts a golf ball and simultaneously acts as a swingweighting medium to variably adjust the swingweight of the club.
