Using the precision accuracy of a laser, four 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. An envelope-stretching groove geometry that optimizes groove dimensions to conforming limits. The larger groove volume channels the most debris possible at impact to improve contact and maximize spin. A wider sole width near the heel and narrow sole width near the toe that improves bunker performance without sacrificing versatility.
