Golf club head

1. A putter-type golf club head that, when oriented in a reference position, comprising:

a main body having a front surface, a rear surface, a top surface, and a bottom surface, the front surface being inclined forwardly in an upward direction at an angle ϕ relative to vertical as measured in a front-to-rear direction; and

a face component comprising:

a first element secured to the front surface of the main body, the first element formed of a resilient material and having a thickness that gradually increases toward a sole portion, the first element comprising a first element front surface, a first element rear surface opposite the first element front surface, and a first element side surface extending intermediate the first element front surface and the first element rear surface, the first element front surface being inclined rearwardly in the upward direction at an angle θ relative to vertical as measured in the front-to-rear direction, the angle θ being between 2° and 6°; and

a second element forward of the first element and comprising a rigid material, the second element secured directly to the first element.

2. The putter-type golf club head of claim 1 , wherein the angle ϕ is 1°.

3. The golf club head of claim 1 , wherein the second element is secured only to the first element.

4. The golf club head of claim 1 , wherein the second element is secured to the first element with a chemical adhesive.

5. The golf club head of claim 1 , wherein the first element side surface further comprises a heel side surface, a toe side surface, a top side surface, and a bottom side surface, wherein at least a portion of at least one of the heel side surface, the toe side surface, and the bottom surface side is visually exposed.

6. The golf club head of claim 1 , wherein the second element comprises a substantially constant thickness.

7. The golf club head of claim 1 , wherein the first element further comprises a flange extending, from a bottom portion of the first element, rearward of the front surface of the main body, flushly with the bottom surface of the main body.

8. A putter-type golf club head that, when oriented in a reference position, comprising:

a main body having a front surface, a rear surface, a top surface, and a bottom surface; and

a face component including:

a first element secured to the front surface of the main body, the first element formed of a resilient material and having a thickness that gradually increases toward a sole portion, the first element comprising a first element front surface, a first element rear surface opposite the first element front surface, and a first element side surface extending intermediate the first element front surface and the first element rear surface; and

a second element forward of the first element and comprising a rigid material, the second element secured directly to the first element;

a forwardmost point;

a rearwardmost point;

a center of gravity having a depth Dcg, measured in a front-to-rear direction from the forwardmost point of the club head; and

an overall club head depth Dch, measured in the front-to-rear direction from the forwardmost point to the rearwardmost point, such that Dch is no greater than 45 mm and Dcg/Dch is no less than 0.42.

9. The putter-type golf club head of claim 8 , wherein Dcg is no less than 12 mm.

10. The putter-type golf club head of claim 9 , wherein Dcg is within a range of 12 mm to 18 mm.

11. The putter-type golf club head of claim 8 , wherein Dch is within a range of 20 mm to 40 mm.

12. The putter-type golf club head of claim 8 , wherein Dcg/Dch is within a range of 0.42 to 0.48.

13. The golf club head of claim 8 , wherein the first element front surface is inclined rearwardly in an upward direction at an angle θ relative to vertical as measured in the front-to-rear direction, the angle θ being between 2° and 6°.

14. The golf club head of claim 8 , wherein the second element is secured only to the first element.

15. The golf club head of claim 8 , wherein the second element is secured to the first element with a chemical adhesive.

16. The golf club head of claim 8 , wherein the first element side surface further comprises a heel side surface, a toe side surface, a top side surface, and a bottom side surface, wherein at least a portion of at least one of the heel side surface, the toe side surface, and the bottom surface side is visually exposed.

17. The golf club head of claim 8 , wherein the second element comprises a substantially constant thickness.

18. The golf club head of claim 8 , wherein the first element further comprises a flange extending from a bottom portion of the first element, rearward of the front surface of the main body, and flush with the bottom surface of the main body.
