An adjustable length putter has a putter head having a contact face adapted to contact a golf ball, a grip portion having a graspable surface adapted to be grasped by a golfer, and a shaft portion connecting the grip portion to the putter head. The shaft portion has a length adjustment mechanism with an outer shaft having a hollow interior, an inner shaft slidable within the hollow interior of the outer shaft, and a clamping mechanism moveable between an unlocked position in which the inner shaft is able to slide within the outer shaft and a locked position in which the inner shaft is prevented from sliding within the outer shaft. The clamping mechanism can be a constrictor clamp, the constrictor clamp having a passageway that receives the outer shaft, wherein the constrictor clamp comprises a clamp actuator that moves the clamping mechanism from the unlocked position to the locked position by changing a cross-sectional dimension of the passageway. The adjustable length putter is moveable from an extended configuration to a retracted configuration by sliding the inner shaft within the outer shaft when the clamping mechanism is in the unlocked position. In one version, a pivot pin of the clamp actuator is located in the front of the shaft portion to assist the golfer in aligning the putter during use.

A golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

The present invention discloses a device designed for use in pickleball, racket sports, and similar sports or activities, incorporating a predetermined layer of strips including hydrogel, positioned at the top of a racket, with alternative embodiments featuring a ferromagnetic mechanism as a complementary or standalone mechanism for picking up pickleballs or other objects, streamlining the retrieval process during gameplay, and reducing fatigue.
