A multi-material golf shaft having a butt portion joined to a tip portion and possessing unique relationships, including rigidity relationships, which provide beneficial performance characteristics.

Briefly, a putter head is provided that concentrates the weight of the putter head at the far ends of the heel and toe of the putter head. The putter head has an ultralight putter body that includes a putter face and a shank for attaching a putter shaft. The ultralight putter body has an axially aligned heel cavity and toe cavity that are constructed to receive weights. The heel weight and toe weights are very dense, and constructed to be received into the respective weight cavity of the light putter body. Due to the extreme concentration of weight at the fare ends of the heel and toe of the putter head, the putter face has exceptional rotational stability with a substantially larger sweet spot than known putter heads. The weights may be provided as changeable weight pairs, such that the overall weight and balance of the putter head may be adjusted, while maintaining the position of the sweet spot.

An improved golf club putter having a selectable hosel, each hosel having a characteristic lie angle and loft angle, wherein the hosel is mounted to the head of the golf club, and wherein the hosel has a position orientation feature which aligns the shaft and hand grip with respect to the putter head for accurate operation of the golf club putter.

Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head may include a body portion having an interior cavity and a front portion. A face portion is attached to the front portion of the body portion to enclose the interior cavity. The golf club head may further include a first filler material coupled to a portion of an inner wall of the body portion, and a second filler material between the first filler material and the face portion and coupled to the face portion. The first filler material has a greater coefficient of restitution (COR) than the second filler material, and the second filler material has a greater stiffness than the first filler material. Other examples and embodiments may be described and claimed.

A putter comprises a handle at an upper end of a shaft of the putter to be grasped by one hand of a user, while an upper portion of the shaft between the handle and the head is to be grasped by a second hand of the user. The handle is arranged for swivelling movement relative to the upper shaft portion along a predetermined angular path defined about a transverse handle axis distinct from a shaft axis so that the handle can be fixedly held by the user and the shaft displaced in forward swinging movement along the predetermined angular path for hitting a golf ball. A putter head is pivotally connected at a lower end of the shaft to be movable about a distinct transverse pivot axis between a starting position in which a hitting plane is substantially parallel to the shaft axis and oblique ending position in which the hitting plane forms an acute angle therewith, such that the hitting plane of the head can remain substantially normal to the support surface after initial contact with the golf ball during the forward swinging movement.

A weight system for a putter type golf club that creates a balance point close to a golfer's hands when the putter is used in a normal manner for execution of a putting stroke. The putter is formed of a putter head, an elongated, constant inch diameter solid metal shaft; and a weighted, cylindrical adapter attached to an upper section of the elongated shaft between an overlying golf grip and the shaft.

A golf club shaft system and golf club shaft possessing unique flexural and torsional rigidity profiles, while providing significant adjustability to fine tune the shaft to a particular golf swing.

To obtain a golf club and a combining member of a golf club shaft and a golf club head that can provide a flexibility in choice of reshafting to a user regardless of types of the golf club shaft and the golf club head. A golf club includes an inner-hosel-type golf club shaft, an over-hosel-type golf club head, and a combining member that combines the inner-hosel-type golf club shaft with the over-hosel-type golf club head.

A golf putter head that can improve the golfer's ability by providing function features that create a consistent setup of putter head position in relation to the golf ball and golfer position in relation to the putter. Once the setup is consistent, further increase in the consistency of the golfer's stroke can be attained through building muscle memory. From the putter stroke, the hitting face can impart an accurate forward motion to the golf ball upon being stricken by the putter head. The putter can provide tactile feedback to the golfer during the golf swing while imparting a forward roll to the golf ball upon striking and can simplify the visual alignment of the putter head to the golf ball.

A resilient face insert for a golf club head, preferably a putter head, is disclosed herein. In particular, the face insert comprises a plurality of hinge features spaced from a striking surface to ensure consistent ball speed across the striking surface. Each hinge feature comprises a tab portion that is spaced from the striking surface by a stem portion and that extends parallel to the striking surface, and is angled with respect to a horizontal y-axis. The orientation of hinge features with respect to the y-axis varies across the face, which reduces sidespin from mishits and produces consistent topspin regardless of impact location of a golf ball on the face insert.
