“Yeah, he ( Mike Taylor ) worked on all these irons. He worked on all my wedges. I talk to him probably every few weeks, giving updates on how I feel, things that I think could be better. He’ll bounce a few ideas off me, what I think, what direction we need to go down the road, how can we make them any better than what they are. And this is the same process I went through all those years when I was working with him at Nike. But now working with him at TaylorMade, it’s a lot more seamless.”
Thanks to the big win by Francesco Molinari at the Arnold Palmer Invitational recently, I think it’s important to evaluate a few things that are very interesting about his equipment, and the equipment used by other players on tour.
First off, even after a banner year, including a major victory at The Open Championship, Molinari made a full-scale equipment change to a full bag of Callaway clubs, including the Chrome Soft X Ball.
Certainly, this speaks to his confidence in the company’s equipment in general. Specifically, though, the most interesting part of this new full bag of Callaway gear are some interesting prototype blade irons, that when asked about were confirmed to Golf.com‘s Jonathan Wall “These [Apex MB] forged blades are made, I think, in Japan, so they’re slightly different from the standard muscle back.”
As you can see below they are similar but clearly are a different shape from the retail offering below.
I decided to point these prototype irons out on Twitter ( Twitter – Ryan Barath ) not realizing the amount of attention it would get. But none the less, it was intended to educate not to create confusion. The one thing that continues to be true with professional golf is that PGA Tour pros (especially ones with majors on their resumes) have access to essentially anything they want from their sponsors including “made for” prototypes. Let’s be real straight here, this kind of stuff has been going on for a long long time even back to persimmon woods, but thanks to social media and full-time equipment coverage, the consumer has the ability to see what’s really going on behind the curtain.
So what are some famous examples of “tour issue” clubs? Where do they come from? Who’s got them? What do they really offer? Let’s take a look back over the last couple decades and find the real gems.
Tiger Woods: multiple sets
Before amateur Tiger became professional Tiger, he was racking up wins with a combo set of Mizuno MP14 and 29 irons. After that, it was on to Titleist, then the BIG Swoosh. At Titleist, Tiger worked with the legendary builder Larry Bobka, and together they created sets just for him. (Full story on The Gear Dive Chats with Larry Bobka)
When Tiger moved to Nike Golf, he was introduced to Mike Taylor. There’s no need to really go too deep on MT’s impact on the game of golf, since so much has already been said, but a quick refresher: his roots run deep with shaping clubs to perfection, from Hogan, to Impact Golf Technologies (Tom Stites post-Hogan Company, which in essence became Nike Golf overnight), to now Artisan Golf. Together, they worked on a number if irons from the original forged blades to the MM Proto.
With Nike’s departure from the equipment space and now being a part of TaylorMade’s staff, Tiger has the ability to work with their entire R&D team, while also benefiting from Mike Taylor’s work at Artisan Golf in Ft Worth Texas, to create the original masters for what are now the P7TW irons.
There was always speculation about this relationship until recently when it was confirmed by PGA Tour.com’s Equipment Writer, Andrew Tursky, during an interview with Tiger
What makes Tiger’s irons unique is they are very square and have a high muscle, which leads to a higher COG. This is the most apparent with his new TaylorMade irons compared to the other P730 model. The other thing with Tiger is that he famously plays what we now consider weak lofted clubs with a 49 to 50-degree pitching wedge, compared to the modern standard of 45. As one of the best ball strikers the game has EVER seen, and someone that has notoriously been an extremely picky player from an equipment standpoint, it makes sense that Tiger wants to see the ball go through very precise windows and feel a very particular way.
Beyond the irons, there are also the many, many prototype fixed-hosel drivers that he played during his time with Nike golf including: Original Forged, Ignite, SQ Sumo, VR Proto, Vr Dymo Tour (also made famous Mr. Anthony Kim) and then finally the Covert. Only a few of these were ever made available at retail.
Mike Weir: Left-handed R7 forged protos
Canada’s favorite lefty. Before signing his agreement with Taylormade, Mike used to play Hogan irons — if you are familiar with the Hogan brand and some of its designs, there are a few classic telltale design traits, including a higher straight (very square) hosel transition to the top line, a good amount of offset, and an overall square look.
In the era of big money on tour, and with Weir’s status as one of the top-15 players in the world during the 2000s, he was able to work into his contract that he would only play irons if they 100 percent fit his eye. It was this little clause (confirmed and not confirmed) that throughout his best finishes (including his Masters win), Mike played a set of completely one-off TaylorMade prototypes.
Weir’s irons were always branded with the most modern line TaylorMade was producing, but the most famous of these were his original left-handed prototype R7 irons. A standard (and very different) retail version of these came out in limited numbers right-handed, but as far as “tour issue” gear goes, these are still considered one of the rarest sets ever produced.
Danny Lee: Luke Donald Personal Grind MP-32s
Although I did a full breakdown on these a few weeks ago (WRX article here), these irons deserve to be in this conversation, not because of their age and recent usage, but as an example of how some tour only gear is really just a small tweak to an already fantastic design. As a Mizuno fan and gear junkie, although they didn’t last a very long time in Danny’s bag, I’m seriously hoping they make a return sometime this year.
Francesco Molinari’s Callaway Apex MBs
I mentioned these off the top, but what I want to discuss is that, although these are clearly not the retail version of the Apex MB, we as consumers should understand that what we are playing is still 100-percent premium equipment. A set of irons like this is way more about looks than performance. Francesco is one of the premier iron players in the game, and like any player that has a crazy repeatable action (and by the way hits golf balls day in and day out FOR A LIVING), he wanted something that fit his eye with squarer lines compared to the standard Apex MB, and Callaway did its part as his sponsor to deliver an iron to his liking. Don’t forget it took a bag full of woods, hybrids, and wedges to help Francesco get another win under his belt.
Sure, not everyone can go out and fully customize the head shape of an Apex MB, but if you are looking to go that extra mile and get exactly what you are looking for there are options out there including Yoro Craft from Mizuno and National Custom Works irons by Don White. Are they pricey? Yep! BUT if you want something all yours, the option is there.
So what does this mean for the average golfer?
It’s extremely important to get custom fit for your irons and approach the process of getting a new set with an open mind. The reason these tour issue clubs exist in the first place is because OEMs want to make sure that their players under contract are using something that fits them to a tee, along with hoping to have these in the winning bag come Sunday afternoon. It’s way better to have your “guy” playing a prototype that he loves and plays well with, then having him feel like he is compromising and running the risk of not playing his best. We all know confidence in equipment means the same to a tour pro as (if not more than) it does to a 15 handicap.
In their own way, what these OEMs are doing is creating a “branded” brand-agnostic bags so that each player has exactly what they need. These designs are still coming from in-house company designers (in 99 percent of cases ), but as we already know, the difference is these clubs are either extremely small batch or one-off prototypes. Same can be said for metal woods, since we have seen examples of fixed hosel Callaway Epic Flash fairway woods, too. The other thing to consider is, thanks to these prototypes, designs are constantly being tweaked, and the next generation of retail clubs might take these preferences built right in — the Luke Donald grind is the perfect example.
GolfWRX was founded with the idea to share these unique clubs and help people see “behind the curtain” when it comes to equipment from every OEM. Whether it be a $4,000 Scotty Cameron 009 that might work just as well as a $150 putter with identical specs, it’s not really about that for “us.” It’s about having something different and unique. Within every group of hobbyists, there are those that seek out the different and rare. From sneakers, to cars, to golf clubs, I’d be completely dishonest if I said the “cool” factor wasn’t part of the what makes these things so interesting in the first place.
When talking to GolfWRX founder Easyyy recently about the history of the site and some of the crazy gear we have seen over the years, we both agreed that there is “something” about playing either tour issue gear, or a club built just for you. The driver you know the exact specs of, the irons with different bounce or grooves, the wedges with grinds you just can’t buy off the shelf — whether they really are better or not, as golfers we want EVERY single last advantage we can get out of our gear, and getting the chance to play these clubs and feeling like there is a positive impact might just be as good as intrinsically superior equipment.
At the end of the day, for us mortals who are buying our own equipment, it’s vital to get the most out any new clubs by keeping an open mind on everything from brand to shaft flex, and in some cases, seeking out a tour issue component. Regardless of brand, choose the 14 clubs that fit you best and the ones you like the look of. Like I said before, confidence in your gear is something you can’t put a price on.

New Mizuno MP-20 irons now available at retail
The 2019/2020 Mizuno MP-20 irons family, the next series of MP irons to connect golfers to the classic “Mizuno Feel,” with four new models (MP20 Blade, MP-20 MMC, & MP20 HMB – Hot Metal Blade), are now available at retail.
The MP-20 series was born from tradition and the idea of creating the ultimate set of irons for every player. Mizuno has accomplished that goal with modern design and an attention to detail on every level with all three models. Speaking to the Mizuno tradition, and something they touched on when these were originally teased on social channels with #LayersOfFeel, Mizuno is going back in time to the TN-87s and reintroducing a copper underlay to their irons—all of them!
It is part of the golf vernacular. It’s ingrained in golf (nerd) culture—it’s a real thing.
But where does it comes from, how did it get here, what is it really, and how is it a component of 2019 Mizuno MP-20 irons?
I’m here to give you some answers and introduce you to MP-20 family of irons from Mizuno.
Born from tradition, and the idea of creating the ultimate set of irons for every player, the 2019 Mizuno MP-20 family is the next series of MP irons that will connect golfers to the “Mizuno Feel.” Speaking to tradition, and something I touched on when these were originally teased on social channels with #LayersOfFeel, Mizuno is going back in time to the TN-87s and reintroducing a copper underlay to their irons—all of them! (Before someone tries to correct me: yes, I realize that they have done this for more recent Japan market model)
What does this copper layer mean? Here’s the funny thing, even Mizuno has had a hard time trying to quantify it. Through multiple rounds of extensive blind prototype testing with all of their staff players, the irons with a copper underlay won on feel EVERY SINGLE TIME! How’s that for dominance?
But why? They are truly still trying to 100 percent figure that out. Mizuno has used its HIT (Harmonic Impact Technology), metallurgy analysis, and every test it can to try and figure out why. Engineers even went as far as trying to prove the hypothesis the copper underlay “feel” was based on nostalgia but time and time again Cu won in blind testing. At the end day, the human element was still the deciding factor because humans are the ones that ultimately hit shots.
2019 Mizuno MP-20 irons
This brings us to the flagship MP-20 (Blade) (The Ultimate Tour Blade as described by Mizuno’s Product Manager & Engineer Chris Voshall). Evolving from the tradition built into the MP-18, and taking design cues from historic models like the TN 87 and MP14, the MP20s provide more flow throughout the set from top to bottom leading to even more control over ball flight. This flow also increases forgiveness (please remember it’s still a blade) and launch in the longer irons, with an increased ability to flight the ball in the scoring clubs…all of this AND a thinner top line.
Now about that top line: it’s an extremely important part of the look of the club, but what many don’t realize is it also plays a big role in feel and acoustics too. Let’s simplify for a moment: think of a clubhead like hunk of metal—a cube—now when you hit that thick piece of metal on something it doesn’t reverberate much and when it does, it’s at a different frequency making it sound heavy and “thuddy,” or as some would say, SOLID.
Now imagine if that same piece of metal, and same mass, was stretched out like a saw blade. Have you ever hit something with the side of a large saw blade? It’s wobbly, loud, and generally unpleasant, that’s what happens when an unsupported part of a club gets too thin, it acts like an amplifier of bad sound, creating terrible feel. By blending a small channel (think MP5) with the classic looks of yesteryear you get a club that feels and performs like no Mizuno before it, and as I said, with a thinner look from address.
What’s all this talk of “Flow”?
Center of gravity and mass placement (or as a Mizuno Engineer explained to me “Vertical Moment of Inertia”). Since each club is designed individually, you need the center of gravity to shift throughout the set to help control launch/trajectory (or “traj” as the kids say), and make sure spin is also at an optimal level.
For the MP-20, it means long irons that are “easier” to hit (air quotes, because like I said before, it’s still a blade), and short irons that can be more easily flighted lower with greater spin and control. Just like with the MP-18s, Mizuno is keeping with the continuous reduced blade length into the short irons for a look preferred by better players and for improved grass and turf interaction.
But What About the Rest?
You might have noticed off the top I called it the “MP-20 Family.” Here’s why: In golf, like with any other industry, data is important. But it’s only as good as you use it and well…let’s just say Mizuno has been paying close attention to how golfers and fitters have been making combo sets over the last few years. It’s all about understanding what golfers really need and thanks to some proprietary data they went even deeper when it comes to designing each and every iron in this family to make sure its performance is maximized. This is why I continue to emphasize how each set has a flow—to make sure each club in your bag is just right for you. Now to introduce you to the rest of the family members…
2019 Mizuno MP20 MMC irons (Multi-Material Construction)
I know, you think you’ve heard this story before but…NOT LIKE THIS!
The new MP-20 MMC is a BIG shift in design, not just because of the Cu underlay, but a radical change in how the whole club is put together. I know it sounds very “big biz,” but in the world of manufacturing it truly comes down to how “parts” are manufactured. Now, with Mizuno, I will reiterate a well-known story. All of its forged irons are single-sourced from one foundry (Chuo) in Japan through a handshake agreement that has been in place for decades.
Now back to the MMC. Before the MP-20 the MMC always had one tiny design difficulty (not a bad one, just a truth) and that was the titanium piece in the back was the same size throughout the whole set. This lead to a set with almost constant sole width. That doesn’t mean previous generations were constructed poorly, but it just means there were improvements that could be made to how the set flowed (there’s that word again) from top to bottom…which leads us to the tech story.
For the first time in the MMC’d life, the titanium piece of the iron will actually vary in mass depending on the club. It will be broken up in the middle of the set to allow better CG placement, and like its blade cousin, improved turf interaction in the shorter irons.
What is also very cool from a build and engineering perspective is the way the titanium gets into the club in the first place. Here we go down a metallurgy rabbit hole, buckle up…
- Titanium has a mass density (rounded) of 4.5 g/cm3 – cubed
- Carbon steel has a mass density of (rounded) 7.9 g/cm3 – cubed
That means that from every cubed cm of steel volume you replace with titanium in the head, you save 3.4g… which might not seem like much, but in a 4-iron for example that has an average mass of 248g for (4) cm3 you save 13.6g or just over five percent. I realize this is DEEP into the mass property weeds, but when you think of what a club head weights and how every half percentage point matters, five percent is a lot! That’s more forgiveness, more MOI, more spin control, and overall better performance.
What is also very cool is all of these parts (titanium and tungsten) have ZERO chemical bond—no epoxy. They all fit snug based on the shrinkage rates of the different materials. Ti & W( tungsten – W comes from the ore Wolframite) shrinks less than the steel so as the steel cools around the titanium and tungsten pieces it creates a mechanical (solid) bond.
All of this together adds up to an iron that looks smaller than the previous version, offers more “flow” in CG, something we mentioned earlier that creates more forgiveness and control throughout the set, and at the end of the day it means a better-engineered version than the one before it.
Hot Metal 2019 Mizuno MP-20 HMB irons
YES…you read that correctly. Mizuno is bringing Hot Metal tech to the MP line!
A hollow body blade looking iron using the same strong yet highly flexible Chromoloy material as the 919 Hot Metals except this time forged to create an iron like they never have before. The look and shape of a blade the speed of a Hot Metal.
Let’s break things down.
The look is clean as clean can be, from there the face of the HMB is thin and fast, while hidden inside the back of the club is complex geometry for both acoustics and precisely positioning mass. These will be the replacement for the MMC Fli-His but unlike that set, only going to the 6-iron, the new HMB will go all the way to the pitching wedge.
What is also different for the HMB vs. the MMC Fli-Hi is the way tungsten is used in the head to create different impact dynamics. The Fli-Hi had all the tungsten (20g worth) in one place in the head (low and towards the toe). The CG was still located right in the middle but through in-depth testing some players found that the Fli-Hi was a more difficult club to turn over and draw.
To improve the workability of the new HMB, the Tungsten was split into two 12g pieces (four more grams than previous Fli-Hi) and positioned into precisely formed pockets on the heel and toe in the back of the club. This allows the unsupported face to flex and makes the club more workable while still maintaining all the forgiveness you would expect from a hollow body iron built for speed. Seriously who doesn’t like the sound of that?
Since the new HMB is a full set and not just long irons, there is more to the tech story… here is comes… better flow and CG positioning throughout the set. This is hugely important for the mid and short irons where loft is already going to create spin so controlling ball flight and traj on approach shots is vital for scoring better.
This is again where the MP-20 Family discussion comes into play. Mizuno knows they are going to sell a lot more HMB long irons vs. blade and MMC long irons, so the entire family is designed holistically for every player to find each and every head that optimizes them on the course.
The Full Package
Like with previous generations going back almost a decade, Mizuno is keeping its industry-leading matrix of shaft and grip options available at NO upcharge. BUT… based on the growing demand for more exotic options the newly expanded shaft line up will include a few shafts that will come with a slight upcharge.
Whatever you end up being fit for, it’s important to realize that there has never been family of Mizuno irons designed like this, which could also mean you could be bringing home some new family members soon.
