A multiple purpose tool assembly for attaching a variety of implements to a handle includes a handle and a rod that is removably coupled to the handle. The rod has a first portion that is slidably coupled to a second portion such that the rod has a telescopically adjustable length. A lock is removably coupled to the second section of the rod. The lock is biased into a locking position for retaining the rod at a selected length. Additionally, the lock is urgeable into an unlocked position thereby facilitating the length of the rod to be adjusted. A plurality of attachments is each selectively and removably attached to the rod for performing specific tasks.

A putter head comprising a novel alignment structure is disclosed herein. In particular, the putter comprises an alignment sphere attached to an upper surface of a lower flange and an alignment ring suspended over the lower flange and vertically aligned with the alignment sphere. When a golfer has oriented the putter properly in front of a golf ball at address, the alignment sphere will appear to the golfer to be encircled by the alignment ring.

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. At least a portion of each hinge feature extends parallel to the striking surface without making contact with the striking surface. In the preferred embodiment, 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. The hinge features may be co-molded with a polymeric backing material having a plurality of parallel grooves in order to further improve performance of the face insert.

Examples of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a body portion of a golf club head may include a cavity having an opening and an internal structure defined by a wall portion and a base portion. A hosel portion may include an insert portion and a neck portion extending therefrom. The hosel portion may be attached to the body portion by an interference fit between the neck portion and the opening of the cavity. The insert portion may be received inside the cavity and may be spaced apart from the internal structure of the cavity. A space between the insert portion and the internal structure of the cavity may be partially or entirely filled with an adhesive to hold the hosel portion in place. Other examples may be described and claimed.

Disclosed are a laser golf putter equipped with a power saving module and a method for reducing power thereof. The laser golf putter includes a golf putter (100) equipped with a putter head (10) at the bottom of a putter shaft, a laser pointer (20) provided in the putter head (10) to emit a laser beam (R1) not identified with a naked eye, a golf ball sensor (30) provided in the putter head (10) to detect a golf ball (40) in front of the putter head, and a switching controller (230) configured to control the driving of the laser pointer (20) in response to the detection of the golf ball sensor (30). The switching controller (230) turns off the laser pointer (20) after a lapse of a set time in a state in which the laser pointer is an ON state when the golf ball (40) is identified.

Provided is a golf putter head, which includes a head body; and a hitting member provided in front of the head body for hitting a golf ball, and to be freely slidable up and down within a predetermined range with respect to the head body. According to the present invention, when the golf putter hits the golf ball, as spin of the golf ball is smoother, directionality of the golf ball is increased.

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.

A golf putter has a hollow shaft that has a longitudinal channel, a grip that surrounds a portion of the shaft, a putter head, and an adjustable counter-balance weight system. The weight system has a rod that has a four-sided configuration and at least one weight. Each weight has an annular weight housing that has a four-sided channel extending longitudinally therethrough, and with each weight housing having a threaded opening. The rod extends through the channel of the weight housing of the at least one weight, and a threaded setting screw is threaded through the threaded opening and impinges on one of the four sides of the rod to secure the weight inside the four-sided channel.

Embodiments of adjustable length golf clubs and methods of manufacturing adjustable length golf clubs are generally described herein. Other embodiments may be described and claimed.

A golf club head, preferably a putter head, comprising a replaceable face insert is disclosed herein. The golf club head comprises a body with face cavity and a secondary cavity in communication with, and disposed behind, the face cavity, and at least one opening extending through a top or sole portion into the secondary cavity. The replaceable face insert comprises a striking portion and a support structure extending from a rear surface of the striking portion. The support structure is received within the secondary cavity and the striking portion is received within the face cavity, and then a rod or bolt is inserted through the opening and through the support structure to reversibly secure the face insert to the body. A linear bearing may be disposed within the support structure to receive the rod or bolt.
