Golf club heads and methods to manufacture golf club heads
Embodiments of golf clubs heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head includes a hosel portion coupled to a golf shaft. The hosel portion is disposed within a space bounded by a center longitudinal plane, a heel boundary plane, a front boundary plane, and a lateral plane parallel to the front boundary plane. The hosel portion is intersected by a heel dividing plane parallel to and equidistant from the center longitudinal plane and the heel boundary plane. The hosel portion is configured to orient the shaft axis toe-ward relative to a center of gravity (CG) location of the golf club head. Other examples and embodiments may be described and claimed.

9. A golf club as defined in claim 8 , wherein the hang angle is greater than 0 degrees and less than or equal to 45 degrees.
10. A golf club as defined in claim 8 , wherein the hang angle is greater than or equal to 45 degrees and less than or equal to 90 degrees.
11. A golf club as defined in claim 8 , wherein the hang angle is greater than or equal to 90 degrees and less than or equal to 135 degrees.
12. A golf club as defined in claim 8 , wherein the hang angle is greater than or equal to 90 degrees and less than or equal to 180 degrees.
13. A golf club as defined in claim 8 , wherein a distance between the shaft axis and the CG location in a heel-to-toe direction of the golf club head is greater than or equal to 3 mm and less than or equal to 10 mm.
14. A golf club comprising:
a golf club head comprising a body portion having a toe portion, a heel portion, a front portion, a rear portion, a top portion, a sole portion, and a hosel bore;
