Introducing the SM8 Vokey Wedges in Tour Chrome from Titleist Golf. Great wedge play comes from distance control, shot versatility and spin. Bob Vokey and his team at Titleist have designed the SM8 Wedge collection to improve your wedges game in all three areas. IMPROVED DISTANCE & TRAJECTORY CONTROL. Introduced in SM6, refined in SM7, and reimagined in SM8. The center of gravity (CG) has been pushed forward, which produces higher MOI. For golfers, this means improved feel and a clubface that simply wants to square at impact.SM8 GRINDS: THE HEART AND “SOLE” OF VERSATILITYYour swing is unique and requires a unique wedge. Master Craftsman Bob Vokey has spent years crafting, developing, and improving his Tour-proven sole grinds to fit players of all levels. MAXIMUM SPIN – ULTIMATE CONTROLS. M8 grooves are cut to the edge to maximize spin and shot control. Each groove on every head is 100% inspected for conformity, and a localized heat treatment is applied to the impact area to double the durability of the groove. PROGRESSIVE CENTER OF GRAVITY.
