1. A golf club head comprising:
- a body portion including a front portion;
a face portion located at or proximate to the front portion, the face portion comprising;
a perimeter defined by a toe edge, a heel edge, a top edge, and a sole edge;
a central strike portion located inside the perimeter and including a geometric center of the face portion;
a plurality of grooves having the same width and depth; and
a plurality of projections defined by the plurality of grooves, each one of the plurality of projections having a volume associated therewith and including a peak portion and a base portion, the peak and base portions each having an area associated therewith,wherein the peak portions of the plurality of projections provide one or more ball striking surfaces and are disposed at a height relative to the base portions of the plurality of projections,wherein the height between the peak and base portions of the plurality of projections is the same across the face portion, andwherein the plurality of projections increase in volume in a first direction moving from the central strike portion to the toe edge of the perimeter, a second direction moving from the central strike portion to the heel edge of the perimeter, a third direction moving vertically upward across the face portion from the central strike portion to the top edge of the perimeter, and a fourth direction moving vertically downward across the face portion from the central strike portion to the sole edge of the perimeter.

Abstract
Examples of golf club heads and methods to manufacture golf club heads are generally described herein. In one example, a body portion of a golf club head may include a front portion. A face portion may be coupled to the front portion. The face portion may include a central strike portion and a perimeter. A plurality of projections may extend from the face portion to provide a ball striking surface for impacting a golf ball. The plurality of projections may be aligned in one or more directions across the face portion and may progressively increase in size in any direction from the central strike portion to the perimeter of the face portion. Other examples and examples may be described and claimed.

9. A golf club head comprising:
-
a body portion including a front portion; a face portion located at or proximate the front portion, the face portion comprising; a toe portion; a heel portion opposite the toe portion; a top portion; a sole portion opposite the top portion; and a central strike portion between the toe portion, the heel portion, the top portion, and the sole portion; a plurality of grooves formed in the face portion with the same width and depth; and a plurality of projections defined by the plurality of grooves, the plurality of projections providing one or more ball striking surfaces, each projection of the plurality of projections having a peak portion and a base portion, the peak portion disposed at a height relative to the base portion, wherein the peak portions of the plurality of projections are coplanar and the base portions of the plurality of projections are coplanar, and wherein the plurality of projections successively increase in volume in a first horizontal direction moving across the face portion from the central strike portion to the toe portion, a second horizontal direction moving across the face portion from the central strike portion to the heel portion, a first vertical direction moving across the face portion from the central strike portion to the top portion, a second vertical direction moving across the face portion from the central strike portion to the sole portion, and a plurality of diagonal directions, each of which moving across the face portion from the central strike portion to one of the toe portion, the heel portion, the top portion, and the sole portion. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A golf club head comprising:
-
a body portion including a toe portion, a heel portion, front portion, a rear portion, a top portion, and a sole portion; a face portion located at the front portion; a plurality of grooves formed in the face portion and including a first plurality of parallel grooves and a second plurality of parallel grooves, the first plurality of parallel grooves extending in a first diagonal direction across the face portion, and the second plurality of parallel grooves extending in a second diagonal direction across the face portion and intersecting with the first plurality of parallel grooves; and a plurality of projections defined by the plurality of grooves and arranged in an array across at least a portion of the face portion, each projection of the plurality of projections having a peak portion and a base portion, the peak portion having a surface area defining a ball striking surface and disposed at a height relative to the base portion, wherein a projection of the plurality of projections is located at or proximate a geometric center portion of the face portion, wherein the rest of the plurality of projections spread out from the geometric center portion toward a perimeter of the face portion, wherein the plurality of grooves have the same width and depth such that the peak portions of the plurality of projections have the same height relative to the base portions of the plurality of projections and the plurality of projections are evenly spaced apart from each other in a first direction moving horizontally across the face portion from the geometric center to the toe portion, a second direction moving horizontally across the face portion from the geometric center to the heel portion, a third direction moving vertically across the face portion from the geometric center to the top portion, and a fourth direction moving vertically across the face from the geometric center to the sole portion, and wherein the plurality of projections successively increase in volume in a plurality of directions moving radially outward from the geometric center portion to the perimeter of the face portion and including the first direction, the second direction, the third direction, and the fourth direction. - View Dependent Claims (17, 18, 19, 20)
