Abstract: Putter type club head with vertical groove patterns are described herein. A putter type club head comprises a putter face having a plurality of first curved grooves and a plurality of second curved grooves. The first curved grooves and the second curved grooves intersect each other at a plurality of points across the putter face. The width and depth of the first curved grooves and the second curved grooves can vary across the putter face in a direction extending from a heel end to a toe end, and/or in a direction extending from a top rail to a sole. The curved groove pattern provides consistent ball speed performance for any impact location on the putter face.

Abstract: 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.

Abstract: Various embodiments of a golf club senor housing are described herein. The sensor housing can include a cover and a base that enclose a sensor therebetween. The sensor housing can be designed to sit on the end of a grip in a position that is non-obtrusive to the user. The sensor housing can further be configured to minimizes the impact on the center of gravity (CG) of the golf club by including mass reducing features. The sensor housing is also configured to sit lower on the grip and reduce the length that it projects outward from the grip butt end. Reducing the added length from the sensor housing creates a less-obtrusive feature.

Abstract: Putter type club head with vertical groove patterns are described herein. A putter type club head comprises a putter face having a plurality of first curved grooves and a plurality of second curved grooves. The first curved grooves and the second curved grooves extend in a general vertical direction, and intersect each other at a plurality of points across the putter face. The width and depth of the first curved grooves and the second curved grooves can vary across the putter face in a direction extending from a heel end to a toe end, and/or in a direction extending from a top rail to a sole. The vertical groove pattern provides consistent ball speed performance for any impact location on the putter face.

Abstract: Embodiments of a golf club comprising a club head, a shaft, and features that improve bonding strength between the club head and the shaft are described herein. The club head comprises a hosel that receives a tip end of the shaft. The shaft tip end defines a shaft bonding area and an effective bonding area. The features described herein are designed to increase the effective shaft bonding area with the hosel to improve bonding strength between the club head and the shaft. In some embodiments, the features comprise microgrooves located within the shaft bonding area. The microgrooves can increase the effective bonding area and provide multi-directional resistance to forces applied to the shaft. In some embodiments, the features comprise a ferrule including a weighting feature that replaces a tip weight. In some embodiments, the features comprise a hot melt weight located within the shaft.
