A golf club head with an interchangeable or reversible sole rail system having a rail member configured to be received within one or more channels formed on the club head. The rail system allows the player to employ rails along a surface of the club head to improve the interaction between the club head and the ground during the swing.

Golf club head with an interchangeable rail system

A set of golf clubs including golf club heads having improved mass distribution characteristics. The set includes golf club heads having a club head main body including a hitting face and a face support, a muscle back shell and a weight insert.

Set of golf clubs

A set of golf clubs including golf club heads having improved mass distribution characteristics. The set includes golf club heads having a club head main body including a hitting face, a muscle back shell and a weight insert disposed in the muscle back shell. The golf club heads have relatively low blade length while maintaining high moment of inertia.

A wedge type golf club head is disclosed herein where the wedge type golf club head has enhanced performance characteristics such as improved backspin, ball speed, and launch angle. More specifically, the present invention relates to a wedge type golf club head having an adjustable center of gravity, where the center of gravity may be adjusted based on different backing profiles that comprises at least one hollow chamber. The wedge type golf club head disclosed above may also have a thickened topline, wherein the thickness of the topline progressively changes as a function of the loft angle of the wedge type golf club head.
