The face portion may further include a first back groove portion on the back surface located proximate to the face toe edge and extending from a location at or proximate to the face top edge toward the face sole edge, a second back groove portion on the back surface located proximate to the face top edge and extending from a location at or proximate to the face toe edge to a location at or proximate to the face heel edge, and a third back groove portion on the back surface located proximate to the face heel edge and extending from a location at or proximate to the face top edge toward the face sole edge. The first back groove portion and the second back groove portion, or the second back groove portion and the third back groove portion may be connected. The first back groove portion, the second back groove portion, and the third back groove portion may be at least partially filled with the filler material.
