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.
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.
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.
