Abstract: Embodiments of a co-molded putter-type golf club head comprising a high-density chassis made of a first material and a low-density putter-type body made of a second material. The first material can be a high density metal (i.e., steel or tungsten, but not limited to). The second material can be a low density thermoplastic composite (i.e., polyphenylene sulfide (PPS), polyamide (PA), but not limited to). The chassis comprises a flow aperture, and one or more interlocking features. The putter-type body portion encases the entirety of the at least one interlocking feature. Further, the putter-type body encapsulates the chassis such that the body extends through, and completely fills the flow aperture, to interlock the body and chassis, and thus form the club head. Other embodiments may be described and claimed.

Abstract: Unlike earlier visual alignment aids, the present devices and methods may transfer focus away from a central sight line to a plurality of multicolored auxiliary sight lines. The multicolored sight lines are typically brightly colored to maintain the player's focus and help avoid head movement during initiation of the swing. Further, in some embodiments, the central and/or auxiliary sight lines are dashed, with the dashes either aligned or offset from one another. In this way, hyper-acuity becomes two-dimensional with sight lines running in a first dimension (e.g., from face-to-back, when markings are on the crown, or top-to-bottom, when markings are on the face) and cross lines, made up of inter-sight line dashes, running in a second dimension (e.g., from heal-to-toe).

Abstract: When hitting a ball to a target with a putter, the ball often travels to a point which is deviated to the right from the target. When a golfer looks at the target just after taking his address, he turns his head to a target about a rotation axis which extends through the back of his head. When this rotation axis is not horizontal and an angle defined by the rotation axis and his sighting line to a putter head is not 90°, he has an optical illusion which tricks him into believing that he has to correct his address position. The patter of the present invention is provided with a thin-plate pendulum thereby allowing him to turn his head about the rotation axis while keeping the angle defined by the rotation axis and his sighting line at 90°.
