“Let’s do something else,” said Callaway’s Chief Designer and wedge-making legend, Roger Cleveland when talking about designing the new Callaway Mack Daddy 4 wedges.

And something else, he did.

Callaway’s Mack Daddy 4 wedges, which the company officially launched on Tuesday, use a new “groove-in-groove” technology that features raised micro-ridges between the main grooves on the faces. Rather than these ridges going below the surface, however, they’re actually “surface positive,” as Callaway explains it; that means they protrude above the surface. Therefore, the grooves and micro-ridges create more points of contact for the golf ball, and they create additional friction to induce more backspin.

In fact, Cleveland himself was so excited about the design, he stood up during our interview and drew out the design on a whiteboard. Professor Cleveland, if you will.

Using new, proprietary cutters, it takes 12 minutes per head to cut the grooves, according to Cleveland. Using a progressive design throughout the set, the lower-lofted wedges — 52 degrees and below — use “20D” grooves, while higher-lofted wedges — 54 degrees and above — use 5D grooves. That means, overall, the higher-lofted wedges are designed to create more spin for greater control around the greens, and the lower-lofted wedges will behave more like your shortest iron. Each of the wedges also have an added groove — Callaway calls it a “nip it” groove — near the leading edge that’s designed to induce more spin when you catch the ball a bit thin.

Maybe the new groove design is why so many PGA Tour players are switching into the wedges so quickly. Sergio Garcia already won with them in the bag at the Andalucía Masters, and Brendan Grace won using them at the Nedbank Golf Challenge. In the 2017 RSM Classic, in fact, there were 30 Mack Daddy 4 wedges already in play.

Grooves aren’t the only difference you’ll notice in the new Mack Daddy 4 wedges, however. Based on Tour feedback, Callaway has designed the wedges with a more compact shape, straighter leading edges, tighter leading edge radii, and slightly more offset throughout the line, according to Callaway.

The MD4 wedges have a progressive offset in the set in order to better blend looks-wise into your set of irons.

“Tour pros like only a subtle amount of leading-edge radius,” said Cleveland, according to a press release. “In the Mack Daddy 4 we gave them enough to make a performance difference while still pleasing the eye.”

As part of the Mack Daddy 4 wedge line, there are now 4 grinds: C-grind, S-grind, W-grind and a new X-grind that has a narrow sole but with high-bounce. Here is the rundown of what each of the grinds delivers, according to Callaway:

• C-Grind: “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. 8-degrees of bounce.”
• S-Grind: “Medium-width sole with slight chamfer at the back and moderate heel relief to keep the leading edge low through impact, promoting solid contact on open-faced shots. 10-degrees of bounce.”
• W-Grind: “Sole is wider at the center and toe and narrower at the heel, with moderate heel relief and generous front-to-back camber. That prevents digging without increasing bounce, and keeps the leading edge close to the turf at impact. Great for open-faced shots. More versatile than our previous W Grind. 12-degrees of bounce.”
• X-Grind: “The newest grind features a narrow, high-bounce crescent sole, with the low point near the front. Excellent for moderate-to-steep attack angles and medium-to-soft course conditions. 12-degrees of bounce.”

The Mack Daddy 4 wedges, which are made from 8620 carbon steel, come in both Platinum Chrome and Matte Black finishes. Like the previous Mack Daddy 3 wedges, the Mack Daddy 4 wedges have four weight ports, and they have milled-aluminum medallions that progressively raise CG (center of gravity) as loft increases to help dial in ball flight, spin and feel appropriately for each loft.

Available lofts include 46, 48, 50, 52, 54, 56, 58, 60 and 64-degree options, totaling 21 loft-bounce combinations. The wedges will come stock with True Temper’s Dynamic Gold Tour Issue 115 shafts and Lamkin UTx grips. Mack Daddy 4 wedges will be in stores on January 26 and will sell for $149 apiece.
