Disclosed herein are golf clubs for reducing the spin imparted to a golf ball, the golf club having a gripping portion around which a golfer can position his hands to swing the golf club, a shaft having a first end and a second end, wherein the gripping portion extends from the first end of the shaft; and a club head extending from the second end of the shaft, the club head having a surface for striking the golf ball, and wherein the surface comprises a high-frictional material to reduce the rotation of a golf ball upon impact with the surface. The striking surface of the golf club may be treated in a variety of manners, including but not limited to placement of an insert into a cavity of a golf club head, material selection, surface material variation, and physical patterning of the surface on a micro-and/or nano-scale.
