  • Patent number: 10434382
    Abstract: A golf club head and a method of manufacturing a golf club head are described herein. The golf club head comprises a club face with a face portion, and grooves positioned on the club face. The grooves each comprise a bottom, a first side wall adjacent the bottom, a second side wall adjacent the bottom, a first top radius adjacent the first side wall, and a second top radius adjacent the second side wall. The club face further comprises a second portion positioned between the face portion, and the first top radius and the second top radius. The second portion of the club face allows for the grooves to appear visually wider to a player, which can provide psychological effects to benefit performance, while still conforming to USGA groove widths standards.

  • Publication number: 20150087438
    Abstract: The invention provides methods of making a component for a golf club by shaping a workpiece by a first process and also shaping the workpiece by a second process that includes electrical discharge machining. A first process such as forging or casting can shape the gross morphology of the workpiece and material can be removed by the second process to form desired features or textures. In certain aspects, the invention provides a golf club head with a club head body having a face, a sole, a toe, a heel, and a hosel extending upwards from a heel-side of the club head body when the club head is at address. A part of the club head body is formed by the first process, with material having been removed from the part by the second process.

  • Publication number: 20150072801
    Abstract: A striking plate of a golf club head includes roughened textured surface portions and scoring line portions. The roughened textured surface portions are spaced apart from each other. Each roughened textured surface portion includes ridges. The scoring line portions are arranged alternatingly with the roughened textured surface portions. Each scoring line portion includes a sunken surface, a surrounding surface surrounding the sunken surface, and two connecting surface segments each extending from one end of the surrounding surface to connect to a respective adjacent roughened textured surface portion. The sunken surface cooperates with the surrounding surface to define a groove that extends along a line.

  • Patent number: 8961334
    Abstract: Putter heads have a ball striking face portion and a rear body portion (as one or more parts). These putter heads may have a DCG/B ratio of at least 0.425 (where B is the overall breadth dimension and DCG is the depth of the center of gravity). Some putter heads may include: (a) a ball striking face body member having a ball striking face with plural openings defined in its central portion; (b) a polymeric material mostly located behind an exterior surface of the ball striking face, wherein a portion of the polymeric material is exposed at the exterior surface of the ball striking face through the openings; and (c) a rear body member engaged with the ball striking face body member. Rear body members or portions thereof can be interchanged to allow for customization and/or better fitting of the putter to the user's putting stroke and/or tastes.

    Abstract: Embodiments of golf club heads having a hydrophobic surface and methods to manufacture such golf club heads are generally described herein. The golf club heads are configured to comprise a ball-striking face and at least two channels formed therein. The channels are separated by a land portion of the ball-striking face extending therebetween. The land portion is associated with at least a first step portion extending at a first elevation and a second step portion extending at a second elevation, the second elevation being higher than the first elevation relative to a bottom of the channels. Each of the first and second step portions is so dimensioned as to be associated with a substantially hydrophobic contact angle.

  • Patent number: 8900064
    Abstract: Putter heads include one or more of a main putter body portion which may including a ball striking face member, a first arm, a second arm, a central member which aligns with the heel-to-toe center of the ball striking face. The central member may include a center portion through which a center line of the putter heads extends and a rear portion. The first arm and the second arm may be symmetrical with respect to the center line of the putter head. The first arm may be configured to be angled towards the center line of the putter head such that the first arm defines a first line which, when extended, is tangent to a portion of an outside diameter of a golf ball when the golf ball is positioned in front of the ball striking member with the center of the golf ball aligned with the center line of the putter head.

  • Publication number: 20140342846
    Abstract: Golf club heads with enlarged grooves, wherein a portion of the finish adjacent or within the groove is removed to create the visual appearance of enlarged grooves. The surface finish of the groove enhancement area surrounding the groove is matched to be the same as the surface finish of the groove, preferably a bright, smooth or shiny metallic finish. This surface finish of the remainder of the striking face of the golf club is a second surface finish, preferably a dark or black matte, or rough finish. The contrast between the two finishes gives the perception that the grooves are larger than they are physically.

  • Publication number: 20140295989
    Abstract: The present invention discloses an iron-type golf club head having features that permit adjustment to the principal moment of inertia angle, the center of gravity location, turf interaction, loft, and overall club forgiveness. In particular, the golf club head includes a rear cavity sized to receive a weight cartridge composed of one or more materials, the adjustment of which changes one or more of the mass properties of the golf club head and also changes the interaction of the golf club head with turf during play. The weight cartridge may comprise one or more high density materials, and may be located in or proximate the sole.
