A golf club with improved weighting characteristic is disclosed. More specifically, the present invention discloses to a golf club wherein the improved weighting distribution stems from an increase in the mass of the golf club at a specific distance away from the butt end or proximal end of the golf club head to help increase the feel and minimize the dispersion of the golf shot by minimizing the pull and or draw tendencies of a golf shot.

Described herein is a system of golf clubs having shafts with ascending weights (shaft weights that increase as shaft lengths decrease). The system of golf clubs can be manufactured by implementing a method called stepping, which allows the system of golf clubs with ascending weights to be manufactured with reduced quantity of inventory.

The stiffness of the golf wood shaft is 210 to 240 CPM (5 cpm), the tip diameter is 8.4 to 9.4 mm, the weight is 40 to 70 g (3 g), the torque measurement at the shaft tip is adjusted to 8 to 6 degrees (0.2 deg), and the position of the center of gravity point of the shaft is set at 55% to 85% (5 mm) from the tip. If possible, with an indication of the center of gravity point of the shaft body or grip body, it is possible to manufacture a golf club that is easy to swing with a butt-heavy center of gravity. Furthermore, it is possible to propose a golf club that is kind and easy not only for professionals but also for amateur golfers.

A tubular steel golf shaft comprising a grip section, a tapered mid-section and a tip section. A loading zone is selectively formed along a portion of the shaft, preferably in the tapered mid-section, comprising a continuous series of closely spaced micro-steps, or reductions in diameter, each of which are less than 0.5 inches in length. Each micro-step section, in the direction from the grip section toward the tip section comprises a first peak which descends to valley and then ascends to a second peak. The diameter of the first peak is greater than the diameter of the second peak. A method of manufacturing the golf shaft is also disclosed.

A multi-component golf club shaft possessing unique characteristics including flexural and torsional rigidity profiles.

A multi-component golf club shaft possessing unique characteristics including flexural and torsional rigidity profiles.

Provided is a golf shaft, capable of ensuring bending rigidity required for a golf club and providing good hit feeling in a composite shaft with 50 g-130 g. The golf shaft comprises an element tube made of metal, an outer layer made of a fiber reinforced plastic and covering an outer periphery of the element tube over an entire length of the element tube in an axial direction, an adhesive layer interposed between the element tube and the outer layer to bond between the element tube and the outer layer, wherein weight of a whole including the element tube, the outer layer, and the adhesive layer is 50 g-130 g, and weight of the element tube is 50%-90% of the weight of the whole.
