Cleveland Custom CG15 BP Wedge. Laser Milled Face Using the precision accuracy of a laser, 4 perfectly calibrated texture lines are milled between each groove exactly to the conforming roughness limit. This breakthrough surface roughness application optimizes ball-to-face friction and maximizes spin under the rules of golf. Zip Grooves An envelope-stretching groove geometry that optimizes gorrve dimensions to conforming limits. The larger groove volume channels the most debris possible at impact to improve contact and maximize spin. Custom Shafts by Accra, Fujikura, KBS, Matrix, Mitsubishi, Nippon, Tour Concept and UST.
