  • Golf club head with tungsten alloy sole component
    Patent number: 8337328
    Abstract: A hybrid wood-type golf club head (20) with a main body (22) and a minor body (24) is disclosed herein. The main body (26) has a front portion (30), a crown portion (25), a partial toe portion (27), a partial heel portion (26), a partial rear portion (28) and a partial sole portion (29). The minor body (24) preferably has a sole wall (31), a partial toe wall (33), a partial heel wall (32) and a partial rear wall (34). The minor body (24) is preferably welded to the main body (22). The minor body (24) preferably has a mass ranging from 80 grams to 130 grams. The minor body (24) is preferably from 55 weight percent to 35 weight percent of the total mass of the wood-type golf club head (20).

  • Hybrid golf club head
    Patent number: 8272974
    Abstract: A hybrid type golf club head is disclosed herein. The hybrid golf club head preferably has an increased heel/toe camber to minimize drag through rough when a golfer swings the hybrid golf club. A sole of the hybrid golf club head is relieved to allow for the face angle to open without the leading edge lifting too high.
