Grooves on Grooves: Callaway launches new Mack Daddy 4 wedges
“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.

TaylorMade is continuing its UDI/DHY series with the successor to the Stealth UDI and DHY utility irons: PUDI and PDHY (which the company styles as P·UDI and P·DHY). TaylorMade is folding the designs in with its P Series of irons.
TaylorMade outlined the process of developing its new utilities this way. The company started with the data on utility iron usage. Not surprisingly, better players — i.e. those who generate more clubhead speed and strike the ball more precisely — were found to gravitate toward the UDI model. DHY usage, however, covered a wider swath than the company might have expected with six-to-18 handicappers found to be bagging the club.
TaylorMade also found that the majority of golfers playing UDI or DHY utilities were playing P Series irons at the top of their iron configurations.
Can you see where this is going?
Matt Bovee, Director of Product Creation, Iron and Wedge at TaylorMade: “As we look to the future, beyond the tech and the design language, we are excited about repositioning our utility irons into the P·Series family. P·UDI is an easy pair for players that currently play P·Series product and P·DHY is an extremely forgiving option for players of all skill levels. It is a natural fit to give these players the performance in this category that they are looking for.”

TaylorMade PUDI

Crafted with tour player input, TaylorMade sought to develop a confidence-inspiring utility iron that blends with the rest of the P Series irons. Also of note: Interestingly, the PUDI has a more compact head than the P790.
In comparison to past UDI products, the PUDI has a more traditional iron shape, slimmer toplines, and less offset with a little of the backbar visible at address.
TaylorMade PDHY

Larger in profile than the PUDI, the PDHY seeks to position center of gravity (CG) lower in the club for ease of launch. The toe height is larger and the profile is larger at address — roughly five millimeters longer than PUDI — the sole of the club is wider for improved forgiveness.
Club Junkie’s take
Golfers who feel like they are missing something at the top of the bag could find the PUDI or PDHY a great option. The look of the PUDI should fit the most discerning eye with a more compact look, less offset, and a thinner topline. If you want a little more confidence looking down the P-DHY will be slightly larger while still being a good-looking utility iron.
For being small packages both models pack a pretty good punch with fast ball speeds, even off-center. The feel is soft and you get a solid feel of the ball compressing off the face when you strike it well. Your ears are greeted with a nice heavy thud as the ball and club come together. The PDHY will launch a little higher for players who need it while the PUDI offers a more penetrating ball flight. Both utility irons could be the cure for an open spot in the top end of the bag.
PUDI, PDHY, or Rescue?
TaylorMade offers the following notes to assist golfers in filling out their bags:
- PUDI has mid-CG right behind the center face to create a more penetrating mid-to-low ball flight
- PDHY has a lower center of gravity to produce an easier-to-launch mid-to-high ball flight.
- Both PUDI and PDHY are lower-flying than the company’s hybrid/Rescue clubs.
- PUDI is more forgiving than P790.
- PDHY is the most forgiving iron in the entire TaylorMade iron family

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:

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.
Huh?
Jan 9, 2018 at 11:28 am
Stan – Where or how are you coming up with this nonsense?
Dan
Jan 9, 2018 at 1:31 pm
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?

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.
