Abstract
Embodiments of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a golf club head may include a body portion having an interior cavity, a port connected to the interior cavity, a toe portion, a heel portion, a top portion, a sole portion, a back portion, a port, and a front portion having a perimeter ledge portion defining at least a portion of an outer boundary of the front portion. The example golf club head may also include a face portion having a front surface with at least one groove and a back surface opposite the front surface and associated with a total back surface area. The back surface may include a first back surface region associated with a first back surface area and a second back surface region associated with a second back surface area. The total back surface area may equal to the sum of the first back surface area and the second back surface area. The first back surface region may be located at or proximate to a perimeter portion of the back surface and coupled to the perimeter ledge portion. Other examples and embodiments may be described and claimed.
