What Titliest Says:
Every Vokey wedge is a demonstration of two distinct realities: the precision of engineering and the artistry of craft. The materials and structure of Vokey SM9 wedges represent our most technologically advanced design, tuned for lower flight and higher spin. But the grind applied to each releases a creative edge that only Bob Vokey can impart.

Details & Benefits:

• Choose Closer - Great wedge play comes from shot versatility, distance control and spin. The materials and structre of SM9 wedges represent our most technologically
  advanced design in all three areas, tune for precise contact, lower flight, and higher spin.
• Ultimate Shot Versatility - Your swing is unique and requires a unique wedge. Finding the right grind for your swing type will provide you flawless contact, so you can
  be prepared to hit every kind of wedge shot in all conditions. For every shot, every lie, every course, there's a grind fit for your swing.
• Precise Distance & Trajectory Control - The bets of both worlds; SM9 goes to new heights, taking the forward center of gravity (CG) and raising it even further,
  promoting a more controlled ball flight and solid contact. Hit it closer more often.
• Maximum Spin - 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 durability of the groove.
• K Grind - The highest bounce wedge in the lineup with a wide, full sole and enhanced camber. The Ultimate bunker club is forgiving from a variety of softer sand and truf conditions.
