Callaway Mack Daddy 4 Golf Matte Black Wedge (56 Degrees, Right Handed)

GROOVE-IN-GROOVE TECHNOLOGY The Groove-in-Groove technology provides more spin through the micro-positive surface texture with micro-grooves. This creates 84 cover-gripping points for max spin. 20D Groove: The lower lofted wedges (52* and below) feature a 20D groove for consistent spin on fuller shots 5D Groove: The higher lofted wedges (54* and above) have an aggressive 5D groove for maximum control out of rough and around the green 8620 CARBON STEEL AND PRECISE CG LOCATIONS The MD4 wedge is built from 8620 carbon steel and precision CG location. The soft feel of the carbon, combined with the four weight ports and milled aluminum medallions, allow for the CG to be precise, increased loft, crisp turf interaction, and a solid feel on every shot.
