A method of customizing a golf club, wherein the method includes generating operating data representative of a user operating a mechanical device. The operating data is generated by a first sensor sized and configured to be removably positioned in a mounting port formed on the mechanical device during operation of the mechanical device. The sensor is interchangeably positionable in the mounting port with at least one mass insert, the at least one mass insert being adapted to be interchangeably positioned in the mounting to provide at least two different mass configurations. The method further includes determining a recommended configuration of the at least one mass insert specific to the user based on the operating data generated by the sensor, and transmitting information representative of the recommended mass insert.

Golf club head customization

A method comprising, in a striking face of a golf club head, the striking face being formed of a first material having a first hardness, creating a plurality of initial grooves, the initial grooves having a first cross-sectional area (A) and a first pitch (P) such that A/P>0.0030 in. The method continues with modifying the initial grooves at least by positioning a second material in each of the plurality of initial grooves, the second material having a second hardness that is less than the first hardness, such that the first material and the second material form a plurality of final grooves each having a second cross-sectional area (A) and a second pitch (P) such that A/P<0.0030 in.

Golf club head and method of manufacturing the same

A golf club head includes a main body having a top portion, a bottom portion, a striking face, and an interior surface. A weight member is coupled to the interior surface of the main body. In an imaginary vertical plane that passes through the weight member, the interior surface of the main body comprises a first point and a second point. An imaginary line passes through the first point and the second point. A first imaginary boundary line and a second imaginary boundary line, both passing through the weight member and being perpendicular to the imaginary line, pass through the first point and the second point, respectively. Between the first point and the second point, the interior surface of the main body has an irregularity factor of at least 1.2 and the weight member comprises a distribution factor of at most 1.0 and a conformity factor of at most 0.07.

Golf club head with a body-conforming weight member

A putter-type golf club head has a main body and a face component including a first element formed of a resilient material. The putter-type golf club head also has a second element forward of the first element and including a rigid material. The second element is secured directly to the first element. The first element has a thickness that gradually increases toward a sole portion of the club head.

An exemplary golf club head having an increased amount of discretionary mass may be realized by utilizing improved drop angles, an improved average crown height, and/or articulation points. The discretionary mass may be placed low and deep in the club head to improve the location of the center of gravity as well as the inertial properties. A preferred break length may also be utilized to further improve the depth of the center of gravity. In one example, the center of gravity may be positioned to substantially align the sweet spot with the face center of the club head.

An iron-type golf club head assembly kit including a club head main body, a first sole component, and a second sole component interchangeably associable with the main body. When the first sole component is associated with the main body, the main body and the first sole component form a first club head comprising a sole surface having a first parting line, formed between the first sole component and the main body, and a first sole contour. When the second sole component is associated with the main body, the main body and the second sole component form a second club head comprising a second sole surface having a second parting line, formed between the second sole component and the main body, and a second sole contour that differs from the first sole contour.

Multi-component golf club wedge

A golf club head includes a striking face having a face center, a bottom portion, a top portion including an exterior surface, a hosel including an imaginary vertical hosel plane, a forwardmost point, and a rearwardmost point. In an imaginary vertical plane perpendicular to the hosel plane and passing through the face center, the exterior surface includes a path having a first point and a second point rearward of the first point. An imaginary infinite straight line passes through the first point and the second point, but does not penetrate the exterior surface. A segment of the imaginary straight line is delimited by the first point and the second point. A maximum distance between the segment and the exterior surface of the top portion is no greater than 0.70 mm and a distance between the first point and the second point is no less than 22 mm.

A golf club includes a striking face, a top portion, a sole portion opposite the top portion, and a shaft assembly. The shaft assembly can include a shaft having a butt end and a tip end, and a shaft sleeve located at the tip end, the shaft sleeve including indicia. The golf club may further include a hosel extending from the top portion, and the hosel can include a sidewall, a tip end, an internal bore for receiving the shaft assembly, a hosel axis, and an aperture extending through, and circumscribed by, the sidewall such that the indicia of the shaft sleeve corresponds with the aperture. The sidewall circumscribing the aperture may include an inner surface having a first thickness Tin a radial direction relative the hosel axis and a chamfered edge having a second thickness Tin the radial direction, T/Tbeing between approximately 3 and 7.33.

Adjustable golf club

A weight member for removable attachment to a weight port of a golf club head is provided. The weight member comprises a head that has a tool mating port for operatively receiving a portion of a fastening tool. The weight member further comprises a shaft that is associated with the head such that the shaft terminates at an end surface. The shaft has a threaded external surface and a non-threaded internal bore that extends from the end surface.
