Abstract: A multi-material skateboard deck comprising fiber reinforced layers that provide structural support while improving the overall skateboard deck mass. The fiber reinforced layers are interspersed between other layers formed of wood and have a perimeter footprint that is smaller and entirely encompassed within the perimeter footprint of the wood layers.

Abstract: Embodiments of golf clubs with grooves and methods of manufacture thereof are described herein. In one embodiment of a golf club described herein, the golf club has a head with a body. The body has a strike face with channels and at least one insert located within at least one of the channels. At least one of the channels comprises a single groove, and the insert forms at least a portion of the single groove. At least one of the channels comprises an opening on the strike face that is narrower than a bottom of the at least one of the channels. Other embodiments and related methods are also disclosed herein.

Abstract: A multi-wheel truck that minimizes wheel interactions with discontinuous and uneven surfaces. The truck provides a suspension system that absorbs impact force caused by uneven surfaces and a unique attack angle that allows obstacles to be traversed when approached from a wide range of angles.

Abstract: A golf club head includes a body having a face plate having a strike surface and an opposing interior surface, a rear end, and a sole connecting the faceplate with the rear end. The face plate, the rear end, and the sole partially define a cavity. An insert is positioned within the cavity, the insert presenting an insert surface facing the interior surface of the face plate and spaced therefrom.

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.

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.

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.

Abstract: A skateboard deck with multiple layers constructed from multiple materials is disclosed. Embodiments for design and manufacture are disclosed.

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.

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.

Abstract: Disclosed herein is a grip comprising an internal bore with an opening having an internal tapered edge. The grip can engage with a tool or a piece of sports equipment. Further disclosed herein is a method of installing a grip onto a tool or piece of sports equipment, including providing a grip having a tubular body; grinding an open first end of the body, wherein the open first end comprises a greatest diameter closest to the exterior of the bore and tapers internally at an angle towards the interior of the bore; providing a shaft or handle; applying an adhesive to a top portion of the handle; sliding the handle into the grip bore until the shaft contacts the a capped second end of the grip; and coupling a surface of the bore to the handle by allowing the adhesive to dry.

Abstract: A golf club head including a club face defined by a toe end, a heel end, a top rail and a sole. The golf club head including a plurality of grooves disposed on the club face between the top rail and the sole. Each groove extends between the toe end and the heel end. Depths of the grooves vary in a direction extending between the top rail and the sole and in a direction extending between the heel end and the toe end. Widths of each of the plurality of grooves vary in a direction extending between the heel end and the toe end.
