Golf club heads and methods to manufacture golf club heads
Embodiments of golf club heads, golf clubs, and methods to manufacture golf club heads and golf clubs are generally described herein. In one example, a golf club head includes a body portion having an interior cavity, a ledge portion extending outward from a back wall of the body portion, a filler material comprising a rubber compound in the interior cavity, a first set of mass portions that is closer to a toe portion edge of the body portion than to a heel portion edge of the body portion, and a second set of mass portions that is closer to the heel portion edge than to the toe portion edge. A face portion is coupled to the body portion to enclose the interior cavity and includes at least one back groove located proximate to a perimeter edge of the face portion. Other examples and embodiments may be described and claimed.

a first set of mass portions located between the toe-side ledge portion and the sole portion edge; and
a second set of mass portions located between the heel-side ledge portion and the sole portion edge,
wherein a distance between the first set of mass portions and the toe portion edge is less than a distance between the first set of mass portions and the heel portion edge, and
wherein a distance between the second set of mass portions and the heel portion edge is less than a distance between the second set of mass portions and the toe portion edge.
2. A golf club head as defined in claim 1 , wherein the first set of mass portions comprises a single mass portion.
3. A golf club head as defined in claim 1 , wherein the second set of mass portions comprises a single mass portion.
4. A golf club head as defined in claim 1 , wherein the toe-side ledge portion has a greater width than the heel-side ledge portion.
5. A golf club head as defined in claim 1 , wherein the filler material is coupled to the back surface of the face portion.
6. A golf club head as defined in claim 1 , wherein the filler material is coupled to an inner surface of the back wall portion.
7. A golf club head as defined in claim 1 , wherein the first set of mass portions or the second set of mass portions comprise a material having a different density than a density of a material of the hollow body portion, and wherein the first set of mass portions or the second set of mass portions are removably coupled to the hollow body portion.
8. An iron-type golf club head comprising:
a face portion having a front surface and a back surface opposite of the front surface, the face portion including a back groove extending on the back surface proximate to a periphery of the face portion, the back groove having a first groove portion located proximate to the periphery of the face portion and a second groove portion transverse to the first groove portion and located proximate to the periphery of the face portion;
a body portion having an interior cavity, the body portion coupled to the face portion to enclose the interior cavity, the body portion having a toe portion with a toe portion edge, a heel portion with a heel portion edge, a front portion, a top portion with a top portion edge, a sole portion with a sole portion edge, and a back portion with a back wall portion, the back wall portion comprising an upper back wall portion, a lower back wall portion, and a ledge portion extending from the upper back wall portion to the lower back wall portion;
a filler material in the interior cavity, the filler material comprising a material having a lower density than a density of a material of the body portion; and
at least one mass portion coupled to the body portion below the ledge portion, the at least one mass portion comprising a material have a greater density than a density of a material of the body portion;
wherein a distance between the at least one mass portion and the toe portion edge is less than a distance between the at least one mass portion and the heel portion edge.
9. An iron-type golf club head as defined in claim 8 , wherein the back surface of the face portion comprises a third groove portion connecting the first groove portion and the second groove portion.
10. An iron-type golf club head as defined in claim 8 , wherein a width of at least a portion of the ledge portion decreases in a direction from the toe portion edge toward the heel portion edge.
11. An iron-type golf club head as defined in claim 8 , wherein a maximum width of the interior cavity is below a horizontal midplane of the body portion and above the at least one mass portion.
12. An iron-type golf club head as defined in claim 8 , wherein the filler material comprises a rubber compound.
13. An iron-type golf club head as defined in claim 8 further comprising a port on the body portion connected to the interior cavity, wherein the filler material is injected into the interior cavity from the port.
14. An iron-type golf club head as defined in claim 8 , wherein the body portion includes a club identifier associated with a loft angle.
15. A golf club comprising:
a shaft having a first end portion and a second end portion opposite the first end portion;
a grip coupled to the first end portion; and
a golf club head coupled to the second end portion, the golf club head comprising:
a body portion having a plurality of recess portions, the body portion comprising a toe portion with a toe portion edge, a heel portion with a heel portion edge, a front portion, a top portion with a top portion edge, a sole portion with a sole portion edge, and a back portion with a back wall portion having a ledge portion;
a face portion coupled to the front portion to enclose the plurality of recess portions of the body portion, the face portion comprising a front surface, a back surface, and a perimeter edge defined by face-toe edge, a face-heel edge, a face-top edge, and a face-sole edge, the back surface comprising at least one groove located proximate to the perimeter edge;
a first filler material;
a second filler material; and
