  • Patent number: 6364787
    Abstract: A golf club wherein a redistribution of weight is provided to increase the moment of inertia but to decrease the swing weight of the club and thus allow increased velocity about the pivot point of the club when using the same energy input or swing, by means of a hollow tubular extension of one to six inches, preferably three to five inches, bearing a weight of 25 to 200 grams, preferably 50 to about 100 grams, at the end of the hollow tubular extension, which weight is thereby upwardly spaced from the gripping surface of the club so as to place the added weight in alignment with the vertical or longitudinal axis of the club shaft and behind the hands of the golfer during a swing, as well as such an extension comprising an adapter for converting a normal golf club to such a club.
