  • Metal golf driver
    Patent number: 4432549
    Abstract: An all metal hollow golf driver is formed by casting a first main part from metal, e.g., stainless steel, in the shape of practically a complete golf driver, except for an opening on one side of the driver body, e.g., the sole side. A second cast part fits within the opening and is weldable thereto to form a complete integral hollow metal golf driver. The weight (mass) of the driver is distributed in order to reduce its torque and/or deflection. The mass is distributed so that it increases from the top side toward the sole side and from the heel end toward the toe.
