  • Publication number: 20260151677
    Abstract: A compact putter-type club head comprising a compact body profile and a small strike surface area is described herein. The compact putter head achieves distinct alignment and delivery advantages under a variety of putting conditions and is uniquely suited to produce accurate putting from the rough or fringe. The small body dimensions, including the strike face, force the player to focus on making a center strike, while also providing minimal resistance when travelling through tall grass. Certain features and characteristics of the compact putter head are specifically tailored to produce one of these benefits, while certain other features or characteristics provide benefits across multiple areas.

  • Publication number: 20260137985
    Abstract: Iron-type golf club heads have a shortened hosel and lengthened hosel bore. The iron-type golf club head allows for a range of loft and lie adjustability post-manufacture with maintained or reduced visible surface deformation and durability loss, and also creates discretionary mass that can be placed strategically for performance benefits. Additionally, a spacer is placed in the hosel bore to suspend a suspended weight and within the hosel bore.

  • Publication number: 20260137986
    Abstract: A wood-type golf club head has a volume between 330 and 400 cm3, a combined MOI greater than 7000 g*cm2, and shaping which balances ground and tee performance. The club head has a large body width and a large body depth that increase MOI, and a proportionally short body height that improves the quality of ground strikes. The club head also has a heavy weight member in a rearward and soleward position to improve MOI and create a CG position that balances both ball speed off the ground and ball speed off the tee. Some embodiments have a club head CG position which favors tee performance. In said embodiments, the club head can comprise a sole slit that improves ground performance and/or performance on low strikes.

  • Publication number: 20260069935
    Abstract: Golf club heads have an opening for receiving a panel with embedded indicia. The panel extends over the opening and includes a composite layer having an interior surface and an exterior surface, embedded indicium coupled to the exterior surface of the composite layer, and a resin layer covering the embedded indicium and the exterior surface of the composite layer. By contemporaneously encapsulating the indicium and composite layer, the resin layer increases durability and prevents the indicium from peeling or falling off of the sole panel upon repeated impacts of the golf club head with a golf ball.

  • Publication number: 20250352866
    Abstract: Embodiments of putter-type golf club head comprising a striking surface capable of achieving consistent ball speeds across the striking surface to account for various ball impact locations are described herein. The striking surface has at least two materials that differ in concentration away from the geometric center of the striking surface to provide this consistency. Consistent (or uniform) ball speed is achieved throughout the striking surface as the portion of the golf ball that contacts the striking surface interacts with at least two materials having a differing material characteristic.
