OVERVIEW: SM9�s new grooves are cut to the edge to maximize spin. Each Vokey wedge is 100% inspected for utmost quality and performance, and a localized heat treatment is applied to the impact area to double the durability of the groove. The D Grind blends versatility from a heel, toe and trailing edge grind and forgiveness with its high measured bounce. The D Grind is for players with a steeper angle of attack who play shots from a variety of club face positions.
