Earlier this week I posted (HERE ) about a new Nike design that I initially thought was a putter and turned out to be a driver. Well this week a related patent application published that throws a few more wild designs in the mix. Check them out!
The drawings come from US Pub. No. T-shape. That is, the opening 325 may extend into the central region 327 of the golf club head body 316 and then communicate with an opening that extends toward the toe portion 330 and heel portion 332 of the golf club head 314. In such a configuration as shown in FIG. 11A, the void 323 is generally T-shaped. As further shown in FIGS. 11A-11C, the golf club head 314 has a first arm 320 and a second arm 322 that extend rearwardly from the front face 334 of the club. At a distal end or free end of the first arm 320, the first arm 320 has a first inwardly extending member 350. Similarly, at a distal end or free end of the second arm 322, the second arm 322 has a second inwardly extending member 352. The first inwardly extending member 350 and the second inwardly extending member 352 are spaced from one another and positioned in confronting relation wherein the opening 325 is defined between the members 350, 352. This arrangement aids in distributing weight associated with the golf club head 314 to the perimeter of the golf club head 314 and, additionally, toward the rear and/or rear corners of the golf club head.
 In some examples, the weight associated with the portion of the golf club head removed to form the void may be between 15 g and 50 g. In still other examples, the amount of material removed to form the void may comprise 5% to 30% of the area or mass of the club head.
I guess the old Bullet Golf “Hollow Point” from the 1990’s was ahead of its time!
