Grooves on Grooves: Callaway launches new Mack Daddy 4 wedges

Published

on

“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.

    I like the look, but will stay with my PM Grind wedges. I don’t understand why more wedges do not have grooves across the entire face, like the PM Grind. Even if I miss off the toe, the shot is still acceptable.

    Funny, the Bridgestone Tour B wedges have also that “new “groove-in-groove” technology”,
    already mentioned in a press release in august last year:

    and already reviewed on WRX in november:

      Cleveland/Srixon have been using this for a while now.

    These hi-tech wedges are only effective for tour players with higher speed swings. Only the top 1% of golfers, which includes gearhead wannabes, will entertain buying these contraptions.
    Btw, in the 1967 book Search for a Perfect Swing (SPS) they tested a smooth grooveless wedge and found insignificant differences in performance compared to a grooved wedge. The testing was done under scientific condition of that time so perhaps the results would be different with these Cally wedges with the fancy face milling.

      I think wedges are one of the few areas of most amateur golfers games that can be in any way like a Tour player. Not the full swing shots, but those around the green are well within the reach of a normal golfer. If you look at a 30 yard pitch, the speed a Tour player uses and an amateur will be very close (providing they are playing the same kind of shot) as the goal isn’t about maximum yardage but the correct yardage. Of all the gear in your bag, wedges and your putter are the clubs that allow you to play a “tour players” game as they don’t rely on physical strength and speed to work

      Grooves are useful once there is anything in the way of the contact between ball and club, so a grooveless wedge is fine from a perfect clean lie, but poor everywhere else, hence all wedges have grooves.

      Stan – Where or how are you coming up with this nonsense?

      The groves are for poor lies. A grove wedge in the rain removes about 2 tsp of water from between the club face and ball. The groves also improve spin out of the rough.

        So, if you hit different types of wedges off a clean tight lie there would be no significant difference between their performance results?

          I buy that….isn’t there an old article that proves that??

      Flawed study.

      Grooveless wedges only perform good under perfectly clean conditions. Like off a turf mat and a perfectly dry/clean ball. If any moisture gets on the ball or clubface the whole thing goes haywire.

      Wedges are designed for slower swing speeds, unlike drivers. Along with putters they are the most relevant.

TaylorMade is releasing its TP Black Copper putters to retail

Published

on

We first spotted TaylorMade’s new TP Black Copper putters at the 2018 PGA Show, but the company wasn’t saying anything about specs, release date, pricing, technologies, nothing.

Then, we all saw Rory McIlroy switch to a TaylorMade TP Black Copper Soto proto putter ahead of the 2018 Arnold Palmer Invitational, which he won by 3 strokes. Of course, Rory’s specific Soto putter was made with a special insert. Click here for all of the info and specs on Rory’s putter.

Now, TaylorMade is releasing retail versions to the public in four models — Juno, Soto, Ardmore 3 and Mullen 2 — which will hit stores on 4/20 selling for $199 with a standard Black Lamkin Crossbone Pistol grip, and $219 with a SuperStroke Pistol 1.0 GT grip.

The putters have a triple-plated finish; nickel, then copper, then black chrome, according to TaylorMade’s Bill Price (Senior Director of Product Creation for Wedges and Putters). They’re then hand-polished to achieve the antique and non-glare finish. Overtime, and especially on the sole, Price says the copper will tarnish or oxidize to unveil a gradually more antique and rustic look. Rory McIlroy himself actually had a hand in inspiring the new finish.

“Rory was talking about certain finishes,” Price said. “He wanted something non-glare, with an antique type finish…. he wanted to be reminded of something old school.” 

Thus, the TP Black Copper finish was born.

Also, the putters are machined from 303 stainless steel, they have adjustable sole weights and have the company’s familiar Pure Roll inserts in their faces. Check out more info about each of TaylorMade’s TP Black Copper models below.
