Abstract: Disclosed herein is a golf club heads having a body portion and a face portion, wherein the face portion comprises a variable thickness profile disposed at an angle on the rear surface of the face plate.

Abstract: Embodiments of multi-component putters comprising an upper portion and a lower portion are described herein. The upper portion is formed from a first material having a first density and the lower portion is formed from a second material having a second density. The first density is less than the second density. The upper portion is affixed to the lower portion via an adhesive or a combination of adhesives and interlocking geometry. The multi-component putter design provides increased forgiveness and moment of inertia compared to a putter formed from a single material.

Abstract: Embodiments of golf coupling mechanisms are presented herein. Other examples and related methods are also disclosed herein.

Abstract: Described herein is a tour iron having a golf club head with a faceplate, a body, and an insert. A sole, top rail, rear, and the faceplate enclose a cavity within the body. The cavity can house the insert. The insert can comprise a low-density material, allowing weight to be concentrated around the peripheral edge of the golf club head. The rear of the golf club head has an inflection seam running from the heel to the toe. The golf club head has an upper portion, above the inflection seam and a lower portion below the inflection seam. The upper portion can have a rear opening. The faceplate, body, and insert can be formed of different materials having different densities. The golf club head has a comparatively high moment of inertia and a low center of gravity. Other embodiments and methods are described herein.

Abstract: Some embodiments include club heads having reinforced club head faces. In one example, the club face comprises a reinforcement element such as a looped rib positioned on a rear surface of the club face to provide reinforcement. The club head further comprises an undercut that extends along the entire perimeter of the club face to provide increased club face bending. The combination of the reinforcement element and the undercut reinforces the club head while permitting the club face to bend. Other embodiments of related club heads and methods are also disclosed.

Abstract: Embodiments of golf coupling mechanisms for joining golf club heads and shafts are described herein. The golf coupling mechanism allows for adjustment of a club head loft angle, a club head lie angle, and a golf club shaft length while utilizing one club head and one shaft. In a fully extended configuration, the golf coupling mechanism includes a shaft sleeve, a removable spacer, and a removable extender, wherein a fastening assembly secures the golf coupling mechanism to the golf club head. In a contracted configuration, the golf coupling mechanism includes the shaft sleeve. The golf coupling mechanism further includes a shaft cap to soften the interaction between the shaft and the golf coupling mechanism. The golf coupling mechanism further comprises one or more arcuate coupler sets to frictionally lock the shaft relative to the golf club head.
