Golf club heads and methods to manufacture golf club heads

A golf club head comprising:

• a body portion including a toe portion, a heel portion, a top portion, a sole portion, a front portion, and a rear portion;
• a face portion located at 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 vertical centerline axis extending between the top edge and the sole edge and passing through the geometric center;
• a plurality of grooves including:
• a first plurality of grooves spaced across at least a portion of the face portion and extending in a first diagonal direction;
• and
• a second plurality of grooves spaced across at least a portion of the face portion and extending in a second diagonal direction that is transverse to the first diagonal direction;
• and
• a plurality of projections defined by portions of the face portion between the plurality of grooves,
• wherein the grooves of the first and second plurality of grooves have the same or substantially the same width and depth,
• wherein the grooves of the first plurality of grooves are increasingly spaced apart in a first direction from the vertical centerline axis toward the toe edge and a second direction from the vertical centerline axis toward the heel edge;
• wherein the grooves of the second plurality of grooves are increasingly spaced apart in the first direction and the second direction, and
• wherein the plurality of projections become increasingly larger in a first outward direction from the central strike portion toward the toe edge, a second outward direction from central strike portion toward the heel edge, a third outward direction from the central strike portion toward the top edge, and a fourth outward direction from central strike portion toward the sole edge.

• 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 arranged in a crisscross pattern across at least a portion of the face portion including the central strike portion;
• and
• a plurality of projections defined by portions of the face portion between the plurality of grooves, the plurality of projections including a smallest projection of the plurality of projections and a remainder of the plurality of projections that are larger than the smallest projection,
• wherein the grooves of the plurality of grooves have the same or substantially the same width and depth,
• wherein the smallest projection of the plurality of projections is located at or proximate the geometric center of the face portion,
• wherein the remainder of the plurality of projections become increasingly larger moving outwardly from the smallest projection of the plurality of projections toward the toe edge,
• wherein the remainder of the plurality of projections become increasingly larger moving outwardly from the smallest projection of the plurality of projections toward the heel edge,
• wherein the remainder of the plurality of projections become increasingly larger moving outwardly from the smallest projection of the plurality of projections toward the top edge, and
• wherein the remainder of the plurality of projections become increasingly larger moving outwardly from the smallest projection of the plurality of projections toward the sole edge.
