  • Golf club shaft
    Patent number: 4431187
    Abstract: A shaft for a golf club includes a first series of step portions, with the step portions increasing in diameter along the shaft from a tip or hosel end of the shaft toward a grip end. The step portions are separated from adjacent step portions by transitional portions which consist of a relatively gentle taper which smoothly link the surfaces of one step portion with another. A second series of step portions is disposed between the first series of step portions and the grip end of the shaft, with the diameter of the step portions increasing by a predetermined amount from the first series of step portions toward the grip end. The second series of step portions are separated from adjacent step portions and from the grip end further transitional portions which are similar to the transitional portions discussed above.
