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)

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.

    Roger Cleveland and Phil must have helped on these. A full set of high toes. Keeping spin off the singers and stunners will be awesome. I give it two thumbs up, and two visor tips, then two more thumbs up.

    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

Golf 101: 5 Tips to building your golf bag with CH3 (+ Charles Howell III WITB)



I think at this point it’s safe to say that Charles Howell III is the adopted son and patron saint of WRX.

Not only is he a member of the site and visits regularly, but he’s also an avid club nerd and tester. I’ve become friends with CH3 over the past couple of years and have had some fun gear geek sessions with him. Want to know the coolest thing of all? He’s still as passionate and curious about gear as we are and not just Titleist (who he is on staff with) he’s curious about it all.

So who better to ask about how to build a great golf bag than with a man who knows it, does, and plays for his livelihood week in and week out?

These are 5 Charles Howell III golden nuggets that any golfer can learn from—and oh yeah, his take on the future is spot on.

Rule #1: Stability over speed no matter what

“Even for the guys on tour, stabilizing the clubface is paramount to good driving. One of the reasons I love testing shafts so often is to see if there is that magic combo of speed and control. However, the stability of the clubhead and shaft have to be there—I could find a combo that’s 20 yards longer, but if it’s something I can’t control, it doesn’t have a place in my bag. Extra yardage is fun until it isn’t.”

Rule #2: Find wedges that can do it all

“I chose the Vokey SM8 M Grind in the 56 and 60, because as the grind spectrum goes, they fall dead in the middle for me but everyone is different. I discovered that finding a middle ground grind wise solves the “different wedges for different grass problems” some players find themselves in. Even at Augusta, there was more Bermuda sticking out than normal which made shots from behind 15 different for example a little trickier. Not only are you chipping back towards a downslope with water behind, but it’s also now into the grain. Knowing I had wedges to combat either scenario made it that much easier. As a player, you have to put all the grinds through the paces and see what one checks off the most boxes. It might be something you never considered.”

Rule #3 Forgiveness looks different for every player

“Iron set makeups have changed so much in recent years. Pay attention to the soles when choosing your irons, even in the longer irons. It would be easy to think that bigger heads wider soles would be a no-brainer to hit, but to be honest, it’s not that simple. Sometimes finding a sole that will help the club get in and out of the ground easily will get you that center contact you were looking for. Although guys on tour may choose beefier long irons, it’s pretty rare to find one with a really wide sole. Soles that large encourage a player to try and sweep it off the turf which is counter-intuitive with an iron in your hand. When getting fit, pay attention to attack angles and center contact with your longer clubs; you may find that thinner soles help you more than anything else.”

Rule #4 Enjoy the process of learning and testing

“Obviously playing for a living gives me the advantage of testing a ton of stuff, but it’s just as fun doing the research at home (online) and understanding what certain equipment can do and the idea behind it. I still rely on testing as much as I can to see what works but it’s the pursuit of knowledge that keeps it all fresh week in and week out. Technology is so good these days but like anything you have to ask questions, look around try some stuff and then make a decision. Remember it’s your golf bag, take some pride in demanding that every inch of it works for you.

Eyes on the future…

“I think as we go down this Bryson/distance chase, the ultimate result on tour will be a lot of two driver bags. Look at it this way, having a 47-inch driver for long bombs, and a 44.5 inch for tighter drives, and a 4-wood isn’t all that hard to imagine. Players can tweak lofts in the irons and wedges easily to adjust to gapping. It’s not rocket science, and I don’t think we are that far from seeing multiple players on tour doing it that way.”

Adidas X Vice Golf launch The Vice Golf Shoe by Adidas



Adidas has teamed up with Vice Golf to launch the new Vice Golf Shoe inspired from off the course which includes a dozen Vice Pro Drip Lime x Adidas golf balls.

The Vice Golf Shoe from Adidas contains ultraboost and a signature lime-green colorway to accent the designs for life both on and off the golf course. The shoe features a camouflage pattern in gray and white on the top of the shoe, while a brand-new drip pattern decorates the boost material at the bottom.

The shoe features branding “discoverables”, such as a subtle Vice logo on the tongue of the shoe while a collab logo is celebrated within. The company’s motto “Embrace Your Vice” runs down the spine of the heel, while another Vice logo lives underneath the 3-stripe caging on the inside of the foot.

If golfers want a brighter color pop, the alternate neon lime laces give that option.

“Based in Bavaria like Adidas, we have always looked up to this global ambassador and brand that has made big moves in both the golf and footwear in recent years. It is a great honor to finally present the result of 22 months of work with tears of happiness when the final pair of shoes arrived” – Vice Golf founder and CEO Ingo Duellmann

In addition to the shoe, the packaging of the Vice Golf Shoe by Adidas is made to look, feel and act exactly like their signature golf ball packages. 

The bottom of the box is wrapped in a neon lime camouflage pattern, and the top cover features the exact, embossed Vice logo colored in neon lime drip pattern as seen and felt on the brand’s golf ball packaging. The connection continues after lifting the lid and discovering an actual box of Vice Pro Drip Lime golf balls, with Adidas logos, sitting in its own compartment.

The Vice Golf Shoe from Adidas (plus one dozen Vice Pro Drip Lime X Adidas golf balls) costs $219.95 and is available to purchase from December 7, 2020, 11 AM EST at
