  • Iron club head
    Patent number: 6569031
    Abstract: A sole of a head is inclined upwardly toward a side of a hosel section. A proximal section of the hosel section, which is continuous to a top, is set to be low. Accordingly, the weight of the head on the side of the hosel section is reduced, while the weight is distributed to circumferential portions of the head. Thus, the moment of inertia is set to be increased, and the sweet area is substantially enlarged.
    Type: Grant

    Assignee: Kasco Corporation
    Inventor: Masayuki Toyota
  • Golf club head
