Callaway today unveiled its Mack Daddy 4 wedge line featuring an all-new proprietary Groove-In-Groove technology that sets a new standard in shot-stopping spin and performance.

The Mack Daddy 4 line is the most rigorously tested and tour-validated wedge family Callaway has ever produced, and represents the finest collaboration to date between wedge design legend, Roger Cleveland, Callaway’s in-house R&D experts, and its global team of staff professionals.

“MD4 sets a new and higher standard in performance and appearance. Shape, feel, spin, control, versatility, finish and detailing have all been elevated to the highest level we’ve ever achieved,” he said.

New Groove-In-Groove technology combines a unique suite of features that provide incredible levels of spin and control:

  • The main grooves are horizontally milled and saw-cut to precise tolerances. In the lower lofts (52° and below) a 20D groove has been used for consistent spin on fuller shots, while higher lofted wedges (54° and above) feature an aggressive 5D groove configuration for maximum control out of the rough and around the green.
  • Each wedge features a 16-groove configuration which also includes a new extra ‘Nip-It’ groove near the leading edge for added control, especially on shorter shots.
  • In-between each main groove on the flat part of the face is a milled ‘Micro-Positive’ surface texture that features three raised micro-ridges, extending the length of the hitting area. Micro-grooves between the ridges then help grab the ball’s cover to increase spin significantly on a variety of shots.
  • This combination of grooves, plus micro-grooves, provides 84 different contact points to grab the cover of the golf ball.

Roger Cleveland’s tireless work on tour refining shapes, soles, grinds and camber has led to a more compact shape, straighter leading edge, tighter leading-edge radius and slightly more offset, compared to MD3 wedges. The tight radius makes it easy to make clean contact on tight lies for maximum spin and control.

The uniquely satisfying feel of MD4 wedges comes courtesy of a soft 8620 carbon steel head (available in an elegant Platinum Chrome, above, or non-glare Matte Black finish, below) and a four-port aluminium medallion weighting system that allows for the precise positioning of the centre of gravity in each head.

The centre of gravity moves progressively upwards as loft increases, ensuring a solid shot and consistent trajectory at all times.

Completing each wedge is a True Temper Dynamic Gold Tour-Issue 115 shaft and premium Lamkin UTx grip.

Available in 21 loft-bounce combinations, including nine lofts – 46°, 48°, 50°, 52°, 54°, 56°, 58°, 60° and 64° – Callaway says MD4 is the company’s most comprehensive wedge line ever.

Also included in the four grind options to suit a variety of playing styles, attack angles and course conditions (adding to C, S and W Grinds) is an all-new X-Grind, which features a narrow, high-bounce (12°) crescent sole, which excels during moderate-to-steep angles of attack on medium-to-soft course conditions.

Mack Daddy 4 wedges will be available from November 17, retailing for $229.99 each. For further information about the complete Callaway product range, visit www.callawaygolf.com.au
