  • Patent number: 5211401
    Abstract: A putter head designed so that, during a normal stroke, the bulk of the weight of the head, not the center of weight, but the weight itself, will be concentrated about a horizontal plane through the center of the ball, thus yielding a very solid shot and one that feels solid. By using a thick upper plate and thin face and sole plates, this unique design feature is accomplished while retaining a conventional ball striking face and a solid sole plate, and at the same time providing a putter head that is pleasing to the eye and easy to align because of its clean straight lines.

  • Patent number: 5007129
    Abstract: A very small, smooth, hand-held pocket tool which opens like a pocket knife to expose a cleaning element, such as a short piece of hacksaw blade, which can be used to clean the grooves and faces of golf clubs and can also be used to roughen the grips of such clubs. The essence of the tool is that it is so small that golfers would not hesitate to carry it in their pocket during a round of golf, yet when open the part that shields the cleaning element acts as a handle making the tool quite large enough to be effective. The cleaning element can easily be replaced when dull.

  • Patent number: 4960278
    Abstract: A pocket-sized divot repair tool which has two strong, thin metal prongs rigidly attached to a disc-shaped handle which contains a spool of very fine, high-strength, man-made line of substantial length fastened to a hookclamp which may be unsnapped from the handle, hooked around a golf flagstick and played out in order to measure relative distance to competing golf balls. The line is retrieved by opening a crank hinged to the spool, after which the crank is closed and the hook/clamp snapped back onto the handle locking itself and the spool firmly into place.
