CALLAWAY MD4 Black Wedge with Steel Shaft
Mack Daddy 4 sets the standard for wedge performance by combining innovative performance technologies with premium components. It’s the finest collaboration yet between industry legend Roger Cleveland and Callaway R&D, and was influenced heavily by Tour pro input.
New Groove-in-Groove Technology for More Spin
- Callaway’s proprietary Groove-In-Groove Technology combines a unique suite of features to provide more shot-stopping spin. The main grooves are saw-cut and horizontal milled to precise tolerances. The lower lofted wedges (52° and below) feature a 20D groove for consistent spin on fuller shots, while the higher lofted wedges (54° and above) feature an aggressive 5D groove for maximum control out of the rough and around the green. The 16-groove configuration includes our extra “Nip-It” groove near the leading edge for added control, especially on short shots. The Micro-Positive surface roughness, milled into the flat parts of the face, features three raised micro-ridges, extending the length of the hitting area, with microgrooves between the ridges that 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. All Mack Daddy 4 grooves are 100% inspected with a digital stylus and special software to ensure the tightest tolerance within the USGA rules.
- The Mack Daddy 4 is the most rigorously tested and Tour-validated wedge we’ve ever offered. Roger Cleveland’s tireless work on Tour refining shapes, soles, grinds and camber 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. “Tour pros like only a subtle amount of leading-edge radius,” said Roger. “In the Mack Daddy 4 we gave them enough to make a performance difference while still pleasing the eye."
