A club head comprising:
- a club head body defining a top rail, a toe rail, a sole rail, and a heel rail, wherein the club head body is made of a first material, wherein only one of the top rail, the toe rail, the sole rail, and the heel rail is engaged to a hollow rail insert made of a second material that forms an enclosed hollow channel extending at least a portion of the hollow rail insert, wherein the first material and the second material are made of a different material.
A golf club comprising:
- an elongated shaft;
- and
- a club head body engaged to the elongated shaft, the club head body defining a top rail, a toe rail, a sole rail and a heel rail, wherein only one of the top rail, the toe rail, the sole rail, and the heel rail is engaged to a hollow rail insert defining an enclosed hollow channel extending at least a portion of the hollow rail insert, wherein the hollow rail insert defines a bulging strengthening section that extends outwardly relative to the club head body in a generally elliptical curved configuration, wherein the bulging strengthening section extends in a direction between the heel rail to the toe rail.
A method of manufacturing a golf club head comprising:
- forming a club head body defining a top rail, a toe rail, a sole rail, and a heel rail, wherein only one of the top rail, the toe rail, the sole rail, and the heel rail defines a cavity;
- forming a hollow rail insert such that the hollow rail insert defines a bulging strengthening section that extends outwardly in a generally elliptical configuration;
- and
- engaging the hollow rail insert to the club head body such that the hollow rail insert and the cavity collectively form an enclosed hollow channel extending at least a portion of the hollow rail insert.
