A golf clip multi-tool apparatus for having a multi-functional and convenient golf tool includes a clip top and a clip bottom. The clip bottom is curved to conform to the curvature of the user's head from the user's temple towards the top of the user's head. A clip top front end and a clip bottom front end are pointed for use as a divot repair tool. A pivot rod is coupled to the clip top and the clip bottom. The clip top and the clip bottom pivot between an open position and a closed position. A pivot spring is coupled around the pivot rod. The pivot spring contacts a clip top inner side and a clip bottom inner side to bias the clip top and the clip bottom to the closed position. The apparatus attaches to the user's hat and may additionally support the user's hair and sunglasses.

Methods for coatings for golf balls, particularly golf balls having thermoplastic polyurethane covers, and the resulting finished balls are provided. The coating is preferably a topcoat comprising a polyurethane composition containing optical brighteners. The topcoat composition preferably comprises a low concentration of optical brighteners. For example, the concentration of optical brightener can be in the range of 0.01 to about 0.20 weight %. The optical brighteners provide the desired brightness to the golf ball without sacrificing color stability. Multi-piece golf balls having inner cores, outer cores, inner covers, and intermediate layers can be made. The finished ball with the topcoat has many advantageous physical and playing performance properties.

A golf ball marking apparatus for precisely hitting on a dimple formed on a surface of a golf ball, includes: a first frame and a second frame which cover the golf ball to accommodate, and are able to be opened to withdraw the golf ball, wherein the first frame comprises: a reference point marking portion which is provided to be able to mark the surface of the golf ball accommodated in the first frame and the second frame by using a writing instrument; a hit point marking portion which is formed to be spaced apart from the reference point marking portion; and a line marking portion which is formed to penetrate along a virtual straight line connecting the reference point marking portion and the hit point marking portion.

A golf tee holder includes a thin box having a top, a bottom and lateral open sides and a thickness based on a diameter of a golf tee. Laterally overlapping filaments (LOF) line the plurality of open sides and provide a friction retention of multiple golf tees inserted through the LOF into the thin box. Furthermore, a clip disposed on the thin box attaches it to a ball cap bill. A golf ball marker comprises a component of the thin box in some embodiments. A spring element within the thin box returns a golf tee pressed into it back out through the lateral overlapping filaments to a user of the thin box. The lateral overlapping filaments comprise one of bristles, fibers, cord, string, fuzz and tuft.

A method for forming a tennis ball including the steps of providing a non-foamed thermoplastic core and providing a non-smooth textured surface on the core. The thermoplastic core including a thermoplastic material having a specific gravity of 0.86 to 1.38, a flexural modulus of 2.0 to 50.0 MPa, and a Shore D hardness of 10 to 70. The thermoplastic material having a thickness between 3.0 and 8.0 mm. The thickness of the thermoplastic material being configured to maintain dimensional stability at internal pressures of between zero and 15 psi.

A sports ball may include an interior bladder and a cover disposed about the bladder. The cover comprises a plurality of adjoining panels, wherein each panel defines a plurality of panel edges that each extend in a predetermined edge direction along an edge length of less than 7.5 centimeters. The cover may further define a plurality of interior channels. Each interior channel extends in a predetermined channel direction along a channel length of less than 7.5 centimeters. The panel edges and the interior channels are staggered, such that each edge direction is obliquely angled with respect to each of the other edge directions, and each interior channel direction is obliquely angled with respect to each of the other interior channel directions and each of the edge directions of the respective panel. Such an arrangement limits directional feature length and promotes a balanced topography upon the exterior surface of the ball.
