A golf club head includes a striking face, a sole portion, a top portion, a hosel, a rear surface, a loft no less than 40°, a virtual vertical plane, and a center of gravity. The striking face has a face center, a leading edge, and a virtual striking face plane. The hosel includes an internal bore configured to receive a golf shaft and includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf shaft. The rear surface is opposite the striking face and has an upper portion and a lower portion, the lower portion including a forward-extending recess. The insert covers the recess forming a hollow portion. The virtual vertical plane is perpendicular to the striking face plane and passes through the face center. The center of gravity is spaced a distance from the virtual vertical plane in the heel-to-toe direction.

Golf club head

A golf club head includes a striking face having a face center and a virtual striking face plane generally parallel to the striking face. The golf club head further includes a sole portion, a top portion, a rear portion, and a loft L no less than 40°. A virtual vertical plane perpendicular to the striking face plane passes through the face center. A club head center of gravity is spaced from the virtual vertical plane in the heel-to-toe direction by a distance Dthat is no greater than 6.0 mm. The golf club head further includes a hosel including an internal bore configured to receive a golf shaft. The internal bore includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf club shaft. The hosel further comprises an auxiliary recess extending sole-ward from the abutment surface of the internal bore.

A correlated set of golf club heads comprises a first and second golf club head. Each club head has a striking face, a rear surface, a top portion, a sole portion, a toe portion, a heel portion, and a loft. The striking face has a first plurality of scorelines defining a scoreline heel-ward extent and a scoreline toe-ward extent. The plurality of scorelines comprises a scoreline length LS1 being the lateral distance between the heel-ward extent and the toe-ward extent. The loft of the second golf club head is greater than that of the first golf club head. The scoreline length LS2 of the second golf club head differs from that of the first scoreline length LS1.

Golf club head with textured striking face

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 striking face with a plurality of scorelines. A first virtual vertical plane is perpendicular to the striking face and passes through a toe-wardmost extent of the scorelines, and a second virtual vertical plane is parallel to the first virtual vertical plane and passes through a heel-wardmost extent of the scorelines. A central region bounded by the first virtual vertical plane, the second virtual vertical plane, and a striking face periphery has a first average surface roughness Ra1 of between about 40 μin and about 180 μin. And a majority of a toe region bounded by the first vertical plane and the striking face periphery is textured to have a second average surface roughness Ra2 no less than 1.5 times Ra1.

A golf club head includes a striking face, a sole portion, a top portion, a hosel, a rear surface, a loft no less than 40&#xb0;, a virtual vertical plane, and a center of gravity. The striking face has a face center, a leading edge, and a virtual striking face plane. The hosel includes an internal bore configured to receive a golf shaft and includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf shaft. The rear surface is opposite the striking face and has an upper portion and a lower portion, the lower portion including a forward-extending recess. The insert covers the recess forming a hollow portion. The virtual vertical plane is perpendicular to the striking face plane and passes through the face center. The center of gravity is spaced a distance from the virtual vertical plane in the heel-to-toe direction.

The golf club head further includes a sole portion, a top portion, a rear portion, and a loft L no less than 40&#xb0;. A virtual vertical plane perpendicular to the striking face plane passes through the face center. A club head center of gravity is spaced from the virtual vertical plane in the heel-to-toe direction by a distance Dthat is no greater than 6.0 mm. The golf club head further includes a hosel including an internal bore configured to receive a golf shaft. The internal bore includes a peripheral side wall and a shaft abutment surface configured to abut a tip end of the golf club shaft. The hosel further comprises an auxiliary recess extending sole-ward from the abutment surface of the internal bore.

A golf club head includes a striking face including a face center, a top portion, a sole including a leading edge and a trailing edge, and a rear side opposite the striking face. The rear side includes a channel configured to permit bending at least a portion of the sole to cause plastic deformation to change a bounce angle defined as an angle between a virtual sole line and a virtual ground plane when the golf club head is orientated in a reference position where the golf club head is addressed to hit a golf ball.

Modifiable golf club head

A method of manufacturing a golf club head includes: providing an intermediate golf club head body; prescribing a scoreline length value based on at least a first final spatial attribute of the intermediate golf club head; and texturing a first region of the striking face to exhibit a first average surface roughness Raof greater than 180 &#x3bc;in by surface milling in a first pass to form a plurality of arcuate micro-grooves each having a radius of curvature selected based on at least a second final spatial attribute of the intermediate golf club head. The method further includes texturing a second region of the striking face to exhibit a second average surface roughness Rathat is less than Ra, and it includes forming a plurality of scorelines in the striking face, the plurality of scorelines defining a scoreline length LS substantially equal to the prescribed scoreline length value.

A system may comprise one or more monitoring devices that may communicate with a mobile device or a wearable device worn by a user of a sporting apparatus. The system may enable motion data specific to motion of the sporting apparatus to be conveniently captured and transmitted, and displayed on the wearable device. The system may include functionality to permit disablement of the motion detecting, transmission, and/or displaying functions at times when such functions are not permitted to be used, and to record the date, time, and location when such functions have been disabled to permit verification thereof by a governing body or sporting organization. The system may further include a learning module enabling monitored motion of the object to be correlated to monitored motion of the user such that predictive motion of the sporting object based only on monitored motion of the user may be obtained and displayed.
