An exemplary golf club head having an increased amount of discretionary mass may be realized by utilizing improved drop angles, an improved average crown height, and/or articulation points. The discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. A preferred break length may also be utilized to further improve the depth of the center of gravity. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head.

Golf club head

A system and method for weighting a golf club. The system is configured to adjust the overall club weight and the weight balance of a golf club. The system includes a weight assembly formed with a plurality of flexible cantilevered arms that interact with a weight member.

A system and method for weighting a golf club. The system is configured to adjust the overall club weight and the weight balance of a golf club.

A muscle-back iron golf club head includes a blade-like upper mass, a muscle-like lower mass, a planar front surface, a top surface, a sole surface, a heel surface, a toe surface, and a rear surface having a first contour. A recess is in the rear surface, the recess having a first portion in the blade-like upper mass and a second portion in the muscle-like lower mass. An insert may be provided in the recess, and such insert may substantially fill the recess and may include a back surface having a second contour which is different from the first contour of the club head rear surface.

Muscle-back, with insert, iron type golf club head

A method for surface treating a golf club head, includes: (a) forming a depression unit in the golf club head, the depression unit being indented inwardly from an outer surface of the golf club head, the outer surface being divided into a working area and a non-working area, the depression unit being formed in the working area; (b) filling the depression unit with a shielding material and covering the non-working area with a covering material; and (c) sandblasting the golf club head after step (b) and removing subsequently the shielding material from the depression unit and the covering material from the non-working area so as to form the working area into sandblasted and non-sandblasted regions that differ in gloss intensity.

A more efficient triangular shape for metal wood clubs or driver clubs is disclosed. This triangular shape allows the clubs to have higher rotational moments of inertia in both the vertical and horizontal directions, and a lower center of gravity.

Metal wood club with improved moment of inertia

A weight member for optimizing weight distribution of a golf club, comprising a removable weight member configured to reside within a shaft of the golf club, the shaft having a proximal end and a distal end, the proximal end opposite a head of the golf club, the distal end adjacent the head of the golf club, the weight member comprising a heavy weighted portion, the heavy weighted portion offset distally from the proximal end of the shaft, the weight member comprising a plurality of locating members, the plurality of locating members configured to limit movement of the heavy weighted portion relative to an inner wall of the shaft.

Golf club with improved weight distribution

In accordance with the present invention, a set of golf club heads is disclosed. The set includes golf club heads with peripheral weights. The dimensions and configuration of at least the peripheral weights are changed from club-to-club along the set so that the center of gravity rises from the long irons to the short irons. By raising the center of gravity from the long irons to the short irons, a golfer will see a peak trajectory height along a line for each club head that is substantially more consistent along that line throughout the set than prior art clubs provide.

Golf club iron set producing flight having consistent angle of descent

A method of constructing a golf club head, comprising affixing a hosel to a shell, wherein said shell comprises a striking face, a sole extending aftward from a lower edge of said ball striking face, and a crown extending aftward from an upper edge of said ball striking face, wherein said shell defines a golf club head interior within said shell, wherein said hosel is configured to receive a golf club shaft, wherein said hosel comprises an internal portion within said golf club head interior and an external portion extending outside said shell, wherein said golf club head comprises a hosel rib affixed to said internal portion of said hosel, manipulating the orientation of said hosel relative to said shell after affixing said hosel to said shell, and affixing said hosel rib to said shell after manipulating the orientation of said hosel.
