Abstract: A method of making a golf club head includes the steps of providing a face of a club head, the face having a ball striking surface and a perimeter defining a border of the ball striking surface, providing a golf club head body that includes a crown, a sole, a toe, and a heel, attaching the face to a front portion of the club head body, and milling the ball striking surface and an edge portion of the face to cut a machined surface into the ball striking surface and the edge portion. The milled surface includes a plurality of first grooves located along the ball striking surface and defining a first depth, and a plurality of second grooves located adjacent the perimeter along the edge portion and defining a second depth. The first depth is different than the second depth.

Abstract: The invention provides golf clubs and methods of making golf clubs with machined perimeter faces. The club faces provide an accurate ball striking surface and improved aerodynamics. In particular, a surface is milled into the club face that expands over an edge of a ball striking surface and onto a portion of the face adjacent to at least one of a crown, a sole, a toe, or a heel. During a swing, the milled surface causes the boundary layer of airflow to separate at a point closer to the rear of the club head, resulting in reduced drag.

Abstract: A golf club head includes a body having a heel and a toe. The golf club head further comprises a sole plate configured to be attached to the body and an interlocking structure formed on a rear surface of the body. The sole plate engages with the interlocking structure to properly align the sole plate with the body.

Abstract: A golf club head includes a heel, a toe, a sole, and a rail. The toe is opposite the heel. The sole is between the toe and the heel. The sole has a forward portion and an aft portion. A forward-aft direction is defined from the forward portion to the aft portion. A heel-toe direction is defined from the heel to the toe. The rail extends outwardly from the sole along the forward-aft direction. The rail and the sole define an open-ended first channel extending along the rail in the forward-aft direction. The rail defines a second channel extending in the heel-toe direction.

Abstract: The invention provides a golf club head constructed from multiple components formed of different materials. In particular, a club head of the present disclosure includes a club head body, such as a cast or forged body portion, made from a first metal, and at least one removable component configured to be releasably attached to the club head body, the removable component being made from a second metal that is different than the first metal. The golf club head includes a semi-hollow, or completely hollow-bodied, ball-striking face cartridge made from at least titanium. In some embodiments, the hollow face cartridge may be integrally formed with the club head body. In other embodiments, the hollow face cartridge may be formed separately from the club head body and may be removed from and re-attached to the club head body.

Abstract: A golf club head with at least one hollow rail disposed on the sole of the club head body, and an insert positioned within at least a portion of the at least one hollow rail. The insert may include a thermoplastic polymer, such as thermoplastic urethane, and may be positioned to beneficially modify a mass distribution of the club head. By providing sole rail(s), a player may benefit from improved ball speed due to the improved interaction between the club head and turf or ground. The golf club head may further include a channel along a length of the sole of the club head, wherein the channel traverses the at least one hollow rail. The channel may extend in a heel-toe direction along the sole and allow greater flexibility in the club head upon impact with a golf ball.

Abstract: The invention provides a golf club head with a lid or cover enclosing a recess such as a channel for an adjustable weight. A golf club head can include a multi-position weight track or other channel or concavity to house a feature such as an adjustable weight mechanism. The club head has a lid that covers the channel, which—when closed—provides an outer surface of the golf club head that does not collect dirt or make whistling sounds when used and thus removes distractions and maintains the club head's intended weight distribution.
