Abstract: Embodiments of golf club heads with energy storage characteristics are presented herein. In some embodiments, a golf club head comprises a hollow body comprising a strikeface, a heel region, a toe region opposite the heel region, a sole, a top rail and an inflection point. The inflection point provides increase bending of the strikeface thereby providing performance enhancement over clubs without an inflection point.

IPC: A63B53/04

Abstract: A golf club head includes a body having a crown opposite a sole, a toe end opposite a heel end, a back end, and a hosel. The golf club head also includes a club face having a loft below a loft threshold in which increasing a coefficient of friction between a golf ball and the club face decreases the spin imparted on the golf ball after impact with the club face. A surface feature positioned on a portion of the club face is configured to increase the coefficient of friction between the golf ball and the club face.

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.
