2021 Callaway X Forged CB, UT, and Apex MB irons launched



Callaway Golf introduces the new 2021 X Forged CB, UT, and Apex MB irons.

The players iron category is the one where technology isn’t the big-ticket item in the conversation. Tour players and top amateurs alike prefer reliability over distance and forgiveness. Look into a good number of our tour pictures, and you will see countless bags with a one-piece forged cavity or muscleback irons.

Over the past four-to-five years, many OEMs have tried to integrate new tech into those irons (i.e. PXG Gen 3 T, TaylorMade P760, and Titleist AP/T100). All of these are multi-material players irons that were designed for the tour and have performed extremely well for a good number of players (Spieth, Jason Day, Zach Johnson, etc).

So what could make that idea better? The above examples all perform to the highest standard on tour and in the retail space…

Well, according to the team at Callaway, the ability to fine-tune for every player was the best place to start. 2021 callaway x forged irons

2021 Callaway X Forged CB


The Goal: To build a tour performance iron that offers the reliability of a one-piece forging while adding technology to offer enhanced forgiveness and the ability to fine-tune each player to exact, optimized specifications.

The Tech Story: The new 2021 Callaway X Forged CB is constructed from a forged 1025 carbon steel chassis and incorporates a multi-material weighting system to manipulate head weights without effecting exact CG placement.


Beginning with the body, the housing of the hollow body design has the addition of external tungsten (standard at 17 grams) weighting system that can go up or down in weight depending on the needs of the player. The idea being that now Callaway has the opportunity to fine-tune swing weight without adding weight to the inside of the hosel, which is a common practice. The issue with that is it can adjust the CG of the golf club, resulting in inconsistencies throughout the set.

With head-specific MIM internal weight out towards the toe, Callaway was able to not only ensure the CG is dead nuts where it needs to be, but it also gives engineers the ability to tailor each weight (density and shape) specific to each head. In the past, internal weights were stock across the set, which can alter the consistency of the head. In this case, each head weight is dialed and cut specifically to match each clubhead.

With a hollow body design (although not taking it as far as the players distance category) there is a level of speed mitigation that is needed to help the best players in the world not hit it too far. Yes, that statement is correct. At the tour level, control, workability, and consistency will always hold a much higher priority than distance. With the 17-4 Tour Tuned faceplate, Callaway focused on adding perhaps a very small percentage of speed off the face but more to optimize the occasional mis-hit than anything else.


What you have now is a face that will offer maybe two percent more speed off the face and an iron that is five percent more forgiving. In real terms, that’s maybe a couple of yards more distance out of the middle and 4-5 yards more carry on a center heel or toe strike. That’s it. Doesn’t sound like much, but for better players, the combination represents the difference between carrying a bunker or hitting it four feet closer to your intended target.

At the elite level, it’s in that nuance that makes or breaks an iron.


The shaping still holds consistent with the 2018 X Forged line—slightly longer blade length than its Apex CB sibling, thin top line, and medium-to-narrow sole. Turf interaction and a softer-than-normal feel were the benchmarks that make the ’18 X Forged popular. However, the 2021 version took it a bit further with a squarer leading edge and a bit more bounce based on Tour feedback. The overall impact experience will be a bit “crisper” based on early testing with Callaway staffer Kevin Kisner.

Tour Response

“Very positive,” according to tour manager Jacob Davidson. “We have multiple staff players testing and/or putting them in play including Na, Kisner, Gooch, Garnett, and a few others.” … “Players are liking the meatier feel at impact and the added forgiveness all while keeping to what they can expect from an X Forged profile.”

2021 Callaway Apex MB


The Goal: Tunability in a muscle back iron. The best players in the world require precision all while maintaining consistency set to set. Callaway wanted to offer this at the highest level.

The Story: The new 2021 Callaway Apex MB is forged from 1025 carbon steel with a classic shape that is similar to the 2018 but with a slightly narrower sole and less offset. 20V grooves ensure optimal spin control in and out of the rough. The chrome-plated 2018 version now has been “brushed” to reduce glare, which is becoming a more popular option.


External tungsten weighting (standard at eight grams) in a muscle back iron isn’t the newest idea ever, but with new technology and a better understanding of precise CG locations, Callaway wanted now to be able to maintain the exact DNA of players set regardless of a grip change, shaft change, etc.

Sounds like a trivial reason to base a new iron on, but in the case of the PGA Tour, it’s not trivial at all. Under normal circumstances, when a player loves a set but wants to make a tweak here or there, it can alter CG and swing weight rather quickly. For example, if a player makes a change into a new grip, it most often leads to a swing weight change resulting in the tour reps either having to add weight to the hosel to match swing weight, add lead tape (awesome) or build a brand new set.

The new Callaway Apex MB gives builders and players the ability to simply use the removable back weight to get the spec back to square skipping common steps and ensuring consistency.



From a shaping perspective, the new 2021 Callaway Apex MB has a few tweaks from its predecessor—slight offset reduction, brushed satin finish, a slight reduction in the top line, modified height in the toe, and the obvious weighting port in the back.

As mentioned in my article about the TaylorMade P7MB, it’s never the goal to completely reimagine a muscle back iron rather maintain predictability, add small tweaks for optics and turf interaction all while maybe adding in 1 or 2 percent of forgiveness, launch, or speed. That’s it.


Tour Response: Since the early prototype was released in late 2019 to a small number of players, the curiosity around the new 2021 Callaway Apex MB has been active. Players were excited to get their hands on them, and since seeding began, players have been switching them in rather quickly. If anything players are loving the fact that the DNA of a Callaway blade is there as well as in some cases increased launch and a bit more forgiveness.

Young Callaway staffer Akshay Bhatia had this to say

“The shaping and feel of these new irons are unbelievable. Center strikes are exactly what you want to feel and I’m loving how they get through the turf. They are simply the best feeling irons I have ever put in the bag.”

2021 Callaway X Forged Forged UT

The Goal: To pack all of Callaway’s key technology into one “players” utility iron.

The Tech Story: The new 2021 Callaway X Forged UT was designed to offer better players all of the game improvement tech Callaway offers and pack it into a utility iron that flows nicely from the top of the bag into the rest of the set. The 1025 carbon steel hollow body design has the same external and internal weighting features as the CB as well as incorporating Callaway’s patented Flash Face Technology for high launch and ball speeds across the face.

For tour players, this is the section of the iron set where versatility is very welcome. Whether it’s hitting a low fairway finder or hitting it straight up in the air, the Callaway X Forged UT gives them every option all while not creating any drama and optically working into the rest of the set. It’s not uncommon for Callaway staffers to put the UT in play in the 2, 3, and 4-iron, so having the ability to tune them to fit each player’s goal is a huge part of this. Some players use a UT as a bridge from irons to woods, and some use them as legitimate replacements for longer irons to add forgiveness and provide some launch and steeper landing angles.

With the 2021 Callaway X Forged UT, Callaway techs can dial in the UT without altering the CG at all, which is the benchmark of launch, tunability, and consistency.

Optics: The 2018 X Forged UT had a shape that the Tour staff adored, so no major changes—the goal here was to keep the look familiar and add the new Callaway tech to dial players in.

Specs: Length/Lie/Offset

External weighting options for fitters and builders only (Light 12G, STD 17G, Heavy 22G)

  • 18: 39.5/60/.090
  • 21: 39/60.5/.085
  • 24: 38.5/61/.080

  • R (80G) S (81G) X (81G, Custom Only)

Grips: Golf Pride Z


  • $250/club
  • Retail: 10/29

Overall remarks

I think what Callaway is doing here is very wise more than anything. Being able to nail a very specific spec for better players is important. The company has always made a sharp-looking players iron and they didn’t try something starkly different here, beyond the added tech.

This is an emotional category based on trust. Callaway knows this and responded with a way for the custom team to ensure even more trust for the player regardless of any alterations one would make (shafts, grips etc). How many times have you had a set of awesome irons that you needed to reshaft and the new combo loses that bit of magic? With the new Callaway X Forged CB and Apex MB you can have your cake and eat it too. I like it.

    I hit the CB and the MB this morning and they feel as good as anything I have ever hit before.

    Both are very playable, but have a divinely shaped “topline.”

    Well done Callaway

What is the benefit of using a wedge instead of PW or GW from the iron set? – GolfWRXers discuss



In our forums, our members have been discussing the pros and cons of using a pitching or gap wedge from an iron set. WRXer ‘jpark0221’ kicks off the thread, asking:

“What is the benefit of doing this instead of using PW from the iron set, which is essentially 10i? I see a lot of pros using wedges from different brands (e.g. Vokey) instead of PW from the same set.”

And our members have been sharing their thoughts in our forum.

Here are a few posts from the thread, but make sure to check out the entire discussion and have your say at the link below.

  • North Butte: “The only way you’ll know is try a different (specialty) wedge instead of the one marked P and see how it works. Give it a couple of dozen rounds, you can’t really tell whether a wedge has an advantage until you get used to playing various shots with it. My point being…they play those wedges because it’s what works best for their game. And you ought to play what works best for your game too. Your best choice won’t necessarily be the same type of club as someone else’s.”
  • Jc0: “If you look a little closer, you’ll notice that most pros who have a specialty 46/48 wedge usually play cavity backs. The speciality wedge is more blade-like to allow a little more control and the ability to play shots a little easier than the PW that matches their set would provide. If a pro plays blades, they usually have the same blade for PW.”
  • PureStrikes54: “Flighting shots lower, getting additional spin for stopping power and to hit it shorter, and minimizing the chance of hitting flier moon balls you can sometimes get with even players cavity irons. At that level, very few players want to be hitting their pitching wedge more than 150 yards. The wedge is a scoring club and is almost always being used to hit knockdowns to tweener yardages.”

TaylorMade unveils all-new P770, P7MC, and P7MB irons



TaylorMade Golf has today announced the latest evolution of its acclaimed P700 Series with the all-new P770, P7MC, and P7MB irons.

TaylorMade P770 Irons

The all-new P770 irons feature a thinner top line, less offset in long irons, and a shorter blade length when compared to the P790. With its hollow body construction and forged L-Face, the 2022 P770 is designed to provide elevated distance, forgiveness, and excellent feel in a smaller sized head.

The P770 features FLTD CG, a strategic design that positions the center of gravity (CG) lowest in long irons and progressively shifts it higher throughout the set to the shorter, weaker lofted irons. The tungsten weighting scheme in the long and middle irons has been redesigned, shifting more weight to the longer irons’ low tungsten mass and a reduction in the middle irons’ tungsten, resulting in an ascending CG through the set.

The aim behind the FLTD CG strategic design is to create easier launch and playability in the long irons while optimizing trajectory and spin in the scoring clubs. 

The P770 irons feature SpeedFoam Air, a technology introduced in 2021 with the launch of the P790. SpeedFoam Air dampens sound and strategically supports the face with a material 69 percent less dense than SpeedFoam, which was seen in the prior generation of the P770.

In addition to the added speed made possible by the thinnest P770 face TaylorMade has produced, the Thru-SlotSpeed Pocket and Inverted Cone Technology aim to help unlock increased ball speed across the face and forgiveness low in the face, where mishits happen most commonly.

“P700 Series irons need to be technical, elegant and timeless and the new P·770 design has all of that in spades. We wanted to take as much performance and hide it on the inside of the iron to where you look at it and it looks like a clean and classic iron with the pearl satin chrome finish and hint of mirror on the toe. On the inside, the technology we have poured in to this iron creates a product that we believe is truly one of one in this space.” – Matt Bovee, Director, Irons Product Creation

Specs, Availability & Pricing

  • Specs: P770 is offered in 3-PW/AW and comes equipped with KBS Tour Steel shafts (X130g, S 120g) as well as Golf Pride Z-Grip 360 in Grey/Black
  • Availability: Pre-order on December 6 at and at retail beginning January 20, 2023
  • Pricing: $1299 USD (steel) and $1499 USD (graphite)

TaylorMade P7MC Irons

The tour-inspired P7MC iron features minimal offset and perimeter weighting.

A narrow sole and tight leading edge aims to ensure consistency through the turf, while TaylorMade’s Compact Grain Forging process uses 2,000 tons of pressure, more than double the industry standard, with the additional force giving TaylorMade engineers precision control at a micro level, producing a tighter grain structure for the best possible feel and strength properties.

Compact Grain Forging seeks to deliver a refined composition inside and out, with the sophisticated craftsmanship coming to life with a satin finish and forged “Metal-T” within the cavity back.

Per TaylorMade, precision in P7MC is paramount, which is why the face of this iron is continued to be machined. Machining the face aims to ensure precision and quality with TaylorMade’s most aggressive score line geometry for exacting shot making.

“There’s no better feeling than a solidly hit forged iron. For pure ball strikers, the consistency of P7MC rivals anything in the marketplace today and has been a favorite among skilled golfers. For players who choose to combo, our cohesive design language allows you to seamlessly pair it with either P770 or P7MB. No two golfers play the game exactly alike, and one of the things I love about our P·700 Series family is the ability for golfers to personalize a set to match their needs and maintain aesthetic unity.” – Matt Bovee, TaylorMade Golf, Irons Product Creation

Specs, Availability & Pricing

  • Specs: P7MC is offered in 3-PW and come equipped with KBS Tour Steel shafts (X130g, S 120g) as well as Golf Pride Z-Grip 360 in Grey/Black
  • Availability: Pre-order on December 6 at TaylorMade and at retail beginning January 20, 2023
  • Pricing: $1299 USD (steel) and $1499 USD (graphite) as seven-piece sets

TaylorMade P7MB Irons

As a result of detailed feedback from testing with Rory McIlroy and Collin Morikawa, the P7MB features a shorter blade length, brand new sole geometry, and progressive offset to create a minimalist profile that’s designed to control shot shape and trajectory.

The sole of P7MB is one millimeter narrower than the previous generation, meaning TaylorMade engineers had to add slightly more bounce to the leading edge which creates a completely different sensation through the turf. Total effective bounce is a combination of sole width and bounce angle, which engineers were able to perfect by increasing the bounce angle to keep the sole from getting caught in the turf.

The shorter blade length of P7MB allowed TaylorMade engineers to create an updated backbar using symmetrical geometry. This allows for more mass to be positioned directly behind the face to support the point of impact and elevate feel.

In addition, the P7MB also features the Compact Grain Forging and machined face and grooves that are also seen in the P7MC irons.

“The narrower sole width of P7MB is a direct result of testing and feedback from Rory McIlroy, Collin Morikawa and our TaylorMade Tour pros. Rory and Collin worked with us to identify the right sole geometry and bounce to match what they were looking for and we perfected that with P7MB. Having two of the best players in the world being a driving force behind the design of this iron have us extremely excited to bring it to the marketplace.” – Matt Bovee, Director, Irons Product Creation

Specs, Availability & Pricing

  • Specs: P7MB is offered in 3-PW and come equipped with KBS Tour Steel shafts (X130g, S 120g) as well as Golf Pride Z-Grip 360 in Grey/Black
