  • Patent number: 4804184
    Abstract: A wood golf club head formed of nonwood material comprises a bulbous body defining a face on one side for striking a golf ball. A hosel is integrally formed with and extends from the body for attaching a golf club shaft. A soleplate defines a spherical roll sole toward the toe of the head and a runner toward the heel of the head. The runner extends generally perpendicular to the ball striking face across the body to define a sole line for the head and is ground to adjust the head for fitting a golf club incorporating the head to an individual golfer. The lie of the golf club can be adjusted by uniformly grinding the runner and/or the face angle of the golf club can be adjusted by grinding the runner to slope toward or away from the ball striking face of the head.
