  • Patent number: 6692378
    Abstract: The present invention relates to a golf club having a golf club head with a channel on the head. The golf club head may be a putter-type club head that is used to putt the golf ball on a green. The use of the channel on the club head provides a mass distribution that can result in a high moment of inertia so that the club head resists twisting in the player's hand when the club head strikes a golf ball. The channel also assists a player in aligning the club head to strike a golf ball. The channel may be located on the upper face of the club head so that the player can see the channel when addressing a golf ball with the golf club. The channel extends from a front, strike face of the club head to a rear face of the club head and is preferably aligned with an axis that corresponds to the desired direction of travel of a golf ball that is struck with the club head.

  • Patent number: 6682439
    Abstract: An improved golf putter head having a striking surface comprised of multiple strings, each string having separate and variable tension capabilities, and a multiple position shaft with adjustable shaft angle capabilities on the back portion of the putter head. The striking surface is comprised of individual, parallel, equidistant adjustable strings across a recessed area between the lined striking face and the front of the putter head to allow for full flexing of the lines without interference from the head structure. The putter head has curved ends with grooves to accommodate and align the strings. The putter head has holes with setscrews at each end of the string groove ends to lock the strings in place once the desired tension has been achieved. These adjustable string tension mechanisms allow the characteristics of the putter face to be changed to create a harder or softer striking surface.

  • Patent number: 6607451
    Abstract: A golf club head having a face section with a polymer surface can provide a more efficient impact between a golf ball and the golf club head. By utilizing a polymer surface with desired material properties of stress, strain and damping levels, the face section will incur higher strain and strain rate levels than the golf ball. These lower internal stresses within the golf ball yield a more efficient impact with a golf club head.
