Improving upon the groundbreaking progressive center of gravity design concept originally introduced with the SM8, the new Titleist Vokey Design SM9 Spin Milled Wedges push the envelope further, with even more innovation.� And it's clear that the SM9 is a true standout, as evidenced by the fact that is has already become the most played wedge on Tour. By adding weight to the topline design, where a tapered pad at the back of the toe helps align the CG properly, the SM9's raised center of gravity produces a more controlled ball flight and solid contact.� The center of gravity is also forward of the face, resulting in increased MOI, exceptional feel and stability, and a club face that simply wants to square up at impact. In addition to the new CG position, the SM9 features a new patented Spin Milled process that maximizes spin and shot control.� The meticulous engineering process begins by cutting the face perfectly flat with a high-speed saw, then cutting every groove individually based on loft and finish.� Low lofts are designed with narrower, deeper grooves, while higher lofts have wider, shallower grooves.� Micro-grooves are individually cut in between the grooves as well, leading to maximum spin on partial shots, a crucial element to successful greenside play.� As if the performance gains weren't enough, Vokey applies a proprietary heat treatment to the impact area, doubling the groove's durability, without impacting feel.� In fact, the SM9 possess' the most durable grooves in golf.� Finally, each groove on every head is 100% inspected for conformity to the rules of golf. Six tour-proven grinds are available in the SM9: F: All-purpose grind particularly suited for full shots and shots hit with a square face.� Ideal for players who prefer a traditional wedge sole.� Most played sand wedge on Tour. M: Designed for players that like to rotate the club face open and closed to manufacture shots around the green.� Ideal for players with a shallower, more swee
