Abstract: A golf club including a club head having a club head main body including a hitting face and a face support, and a support extension. The support extension extends between the face support and a back flange to define a lower cavity.

Abstract: A wedge type golf club head with improved performance characteristic is disclosed herein where at least a striking surface of the wedge type golf club head is coated with a polymer coating to decrease the coefficient of friction as well as create a hydrophobic surface to remove dirt and debris. More specifically, the present invention discloses a wedge type golf club head with a hydrophobic polymer coating that creates a contact angle of greater than about 90 degrees as well as decreases the coefficient of friction to be less than about 0.1.

Abstract: A golf club head with a hardened striking face portion that improves durability and performance is disclosed. More specifically, the golf club head disclosed may have a martensitic striking face portion that may be at least about 1.3 times harder than the rear portion of the golf club head due to the martensitic crystalline structure of the striking face portion foamed by heating and quenching the striking face portion of the golf club head.

Abstract: The present invention is directed to a modular golf club. In particular, a golf club includes a plurality of components that are removably coupled so that the physical attributes of the golf club head may be tuned. The inventive golf club head includes a body member and at least one of a removable sole member and a removable face member.

Abstract: A golf club head having a replaceable striking face is disclosed herein. More specifically, the present invention discloses a golf club head where at least a portion of the frontal striking surface of the face is detachable and replaceable to improve performance. A golf club head in accordance with the present invention may generally have a thinned striking face with a thickness of less than about 3.0 mm yielding a golf club head with a larger sweet spot that's greater than 6% of the frontal striking surface; defined as an area of the frontal striking surface having at least 99% of the maximum characteristic time between about 239 microseconds to about 257 microseconds.

Abstract: The present invention is directed to a golf club head with an improved striking surface. The grooves are machined into the strike surface with tight tolerances using a profiled cutter.

Abstract: A set of golf clubs including golf club heads having a progressive effective sole width through the set. The set includes golf club heads having a club head main body including a hitting face and a face support. A portion of the set includes golf club heads having trailing edge sole chamfers that reduce the overall sole width to the effective sole width.
