Abstract: A “Concave Golf Club Assembly” having a curved concaved head face, which is designed to help a golfer drive a golf ball further and to its target more accurately, because the face of the club head is concaved, and its sweet spot location on the face of the club head and its shaft location at the club head, and a sight line located on top of the club head. The sweet spot is where the center-line of the head will pierce the face of the head. The club shaft is attached to the head so that its center-line will intersect the center-line of the club head. The centerline of the head is a line drawn from the center of gravity of the head to a perpendicular line that is tangent to a curved concaved surface, and is parallel to the ground, and is at the same height as the center of gravity of the head. This club head includes a high lighted straight line on the top of a fore and aft rib that is above and parallel to the center-line of the club head.
