Abstract
An angled putting golf club head has a forward-angled face comprising a plurality of teeth constructed so as to impart to the ball a horizontal force with little or no vertical force at the point of impact, and to contact the ball above its center of gravity so that the ball has negligible sliding motion when first struck.

1-16. (canceled)
A golf club head comprising:
- a top-forward angled face;
- and,
- a plurality of generally forward-facing teeth, wherein each of the teeth has a tooth tip for striking a ball, wherein each of the teeth comprises an upper tooth surface and a lower tooth surface intersecting the top-forward angled face and meeting at the tooth tip such that the tooth tip is in a top forward plane, wherein the upper tooth surface and the lower tooth surface of each tooth form an angle B at the tooth tip, and wherein 90°≦B≦104.12°. and wherein each of the teeth has a height of about 0.2 to about 0.3 inches measured from a line defining a base of a tooth to the top of the tooth.
A golf club head that imparts a pure forward rotation to a golf ball at impact between the golf club head and the golf ball, the golf club head comprising:
- a top forward angled face;
- a plurality of teeth extending from the angled face, wherein an angle of the face and the teeth are arranged to impart forward rolling motion and substantially no sliding motion on a golf ball immediately upon impact by the club head substantially according to the following equation:
- v0=rω0
- wherein v0 is the initial horizontal speed of the golf ball at impact, wherein ω0 is the initial angular speed of the golf ball at impact, wherein r is the radius of the golf ball and wherein each of the plurality of generally forward facing teeth a has height of about 0.2 to about 0.3 inches measured from a line defining a base of a tooth to a top of the tooth.
