Callaway Golf’s Mack Daddy 4 wedges have 84 grooves and micro-grooves for more spin

For the next generation of Callaway Golf's Mack Daddy wedges, Roger Cleveland, who has done pretty much all there is to do in wedge-making, said he wanted to do something different. So, he did.

The end result of that project is the Mack Daddy 4 wedges, packed with Groove-in-Groove Technology, a set of features to impart spin on the ball and get your wedge shots to check up faster.

The 15 main wedge grooves on the 8620 carbon steel head are saw-cut and horizontal milled, with the lower-lofted wedges (52 degrees and below) featuring a wider 20D groove for consistent spin on fuller shots, with the higher-lofted wedges (54 degrees and above) featuring narrower 5Ds groove for maximum control out of the rough and around the green. There's a 16th main groove, dubbed the “Nip-It” groove, near the leading edge for added control, especially on short shots. Center of gravity moves up the face as loft increases to help dial in trajectory.

Milled into the flat parts of the face is what's called Micro-Positive surface roughness, which are three raised micro-ridges, extending the length of the hitting area to bleed just outside the groove lines. In between the micro-ridges, the Mack Daddy 4s feature micro-grooves that help grab the ball to increase spin significantly on a variety of shots. With the 16 grooves and the micro-grooves, there are 84 different contact points on the face.

These wedges have a more compact shape and straighter leading edges, based on Tour feedback. There's also a tighter leading-edge radii. The offset has been slightly increased throughout.

There are four grind options in the Mack Daddy 4s, including a new X grind:

  • C Grind (8° bounce): Increased relief, especially at the heel, making it easier to play shots with the face open. Ideal for medium-to-shallow attack angles and/or firm course conditions.
  • S Grind (10° bounce): Medium-width sole with slight chamfer (sloping edge) at the back and moderate heel relief to keep the leading edge low through impact, promoting solid contact on open-faced shots.
  • W Grind (12° bounce): Sole is wider at the center and toe and narrower at the heel, with moderate heel relief and generous front-to-back camber. Designed to prevent digging without increasing bounce. Ideal for open-faced shots.
  • X Grind (12° bounce): Features a narrow, high-bounce crescent sole, with the low point near the front. Designed for moderate-to-steep attack angles and medium-to-soft course conditions.

The Callaway Mack Daddy 4 wedges come in the Platinum Chrome or Matte Black finish with the Dynamic Gold Tour-Issue 115 shaft. There are 21 loft-bounce combos to choose from, so there should be something for you in there. The wedges will be available January 26 for $150 each.
