  • Iron-type golf club head with chamfered leading edge
    Patent number: 8197355
    Abstract: An iron-type golf club head having a coated stepped sole is disclosed herein. The coated stepped sole is stepped such that the sole surface furthest from the face is raised away from the turf to minimize the turf contact through a golfer's swing particularly for the longer, less lofted irons. The surface friction is reduced by applying a thin dense chromium coating thorough electroplating to the stepped sole.
