GolfWRX Spotted: Mizuno JPX 921 Forged (Update: JPX 921 Tour, too)



Update: 6/29: 10:30 P.M. Bo Hoag tweeted this shot of his JPX 921 Tour irons, indicating they are “coming 9/17/20.”







Mizuno just dropped a teaser image of the newest JPX 921 iron. Let’s call it the “921 Forged” since “Forged” is featured in the cavity.

Although we don’t have all the details about the new JPX 921 or an official release date yet (although Mizuno mentions 9/17 in its social media posts), there are a couple of things we can extrapolate from the image that give some possible clues to what might be in store.

Heat (ball speed): The first thing we notice is the obvious “heat” or steam coming from iron in the short clip (great camera work or graphics there). The JPX series has been synonymous with fast ball speeds and if the image is any indication the JPX 921 Forged is going to deliver on that message. I mean, there has never been an OEM to predominantly feature a turtle or sloth in their marketing material for good reason—although there was a time when puppets were used to sell drivers, but that’s another story for another day.

A post shared by Mizuno Golf North America (@mizunogolfnorthamerica) on

Forged Chromoly: This is the big one here! The hosel of the iron clearly stated GF Forged HD Chromoly, which to break it down means: Grain Flow Forged High-Density Chromoly. On the hosel of the Mizuno MP20 HMB it says GF Forged Chromoly but not HD, which I believe was done since the MP-20 HMB was a two-piece iron with the face and hosel forged from the Chromoly material, and the back body is a separate piece welded.

This little marking could be a clue that the JPX 921 Forged is a one-piece forged head from Chromoly, which would be a first for the company. It could also potentially mean that this club is geared more towards the better players, and the clean lines could be part of that indication.

Either way, on the heels of the highly regarded MP-20 line and the previous JPX 919 series, the new 921 irons are looking to be a very big release for Mizuno.

    Looks like a copy of the Ping i210. Except a little busier and less durable.

    • RobK

      Jul 29, 2020 at 10:35 am

      I think it looks a lot more like the 919s lol

    People are such suckers for “forged”. Chromoly is hard af. Don’t care what you say, it’ll go far but it ain’t gonna feel soft.

    • RobK

      Jul 29, 2020 at 10:36 am

      It will be softer then the boron infused in the 919

    If this is a forged version of the Hot Metal Pro…I’m inp

    • RobK

      Jul 28, 2020 at 11:38 pm

      Well the 921 is forged in chromoly. Where the 919 hmpro was cast in chromoly. The head size on the 919 forged and hmpro were very similar, I think the forged was slightly thinner. So this new 921forged is basically the forged version of last years 919 hmpro, sorta? Lol. I know you get what I mean. And I’m sure there’s other new “tech” in there we don’t know about yet.

    Maybe there is hope that a Hot Metal version of this also becomes a forged club?

    I traded my old first generation Callaway Apex for the 919 Hot Metal. Even if the feel (sound) of the Hot Metal is OK the Apex with it’s combination of forged body and thin steel face was even better. If Mizuno could do the same and combine a Chromology forged body with a nice thin face for ball speed I think it would be awesome!

      Sorry I meant to write that comment to the other guy comparing these to the hot metals but the pro’s.

    Yes. I am buying them.

    I’m a 6.5. Could I game these?

    • BigDshooter

      Jul 27, 2020 at 10:06 pm

      I’m 8.5 and could game you all night long

    A skillion dollars for 14!

    • Robin

      Jul 28, 2020 at 8:17 pm

      Not many people buy 14 irons, so probably only half a skillion dollars.

  8. Tess

    Jul 27, 2020 at 8:32 pm

    I need to investigate these babies more closely. In a word, to my eye, stunning. Some say you can’t see the back of the iron at address. So be it. However, walking up to my bag and seeing an appealing, powerful looking cavity is inspiring.
    Go Mizuno!

    wouldnt mind a degree strong on this line

    • T

      Jul 27, 2020 at 8:45 pm

      If they follow lofts of the 919 Forged, the 7i is already 32 degrees. I don’t think they will be any stronger than that. You get into Hot Metal irons at 30 degrees for the 7i

  10. straightonly

    Jul 27, 2020 at 6:29 pm

    No offset and I might consider them.

    • brian

      Jul 27, 2020 at 7:44 pm

      Move along then. You’re only going to find “no offset” in blades.

      • djlawrence3557

        Jul 27, 2020 at 9:47 pm

        The 919 4i had 0.152 and the Tour was 0.126. I think there’s hope.

  11. James

    Jul 27, 2020 at 6:16 pm

    So which is more durable: 1025 Boron or HD Chromoly? Serious, intelligent answers please.

    • RobK

      Jul 27, 2020 at 7:56 pm

      Definetly the boron. As a JPX919 forged player, I can’t wait to get these and remove the boron. The boron is like tungsten, adds some weight to the flu head and makes it a little harder(more durable)

  12. Scott Francis

    Jul 27, 2020 at 4:17 pm

    Yeah they look identical to 919

  13. johnny p

    Jul 27, 2020 at 3:49 pm

    Irons all look the same anymore

  14. RobK

    Jul 27, 2020 at 1:52 pm

    No more boron? That means the only question is- is how much I’ll get for my JPX919 Forged trade in.

    • T

      Jul 27, 2020 at 4:15 pm

      If I’m not mistaken, and from what I have read, Chromoly is a more expensive material then the boron infused carbon steel of the 919. I think the real question will be, how much is Mizuno going to charge for the JPX921 Forged?

      • RobK

        Jul 29, 2020 at 10:32 am

        Price isn’t changing. Even if it was- it wouldn’t be a question I care about. Just how much am I getting for my 919

Top 3 ways to easily customize your clubs



At GolfWRX, we show off a lot of cool stuff that often requires some serious tools or expensive equipment—for example getting your hands on a full-scale launch monitor can cost upwards of $15,000. So, we want to show you some of the ways you can refresh and customize your current gear at home within a “do-it-yourself” budget.

Change your grips

Changing your grips for the sake of customization, or because they are finally on their last legs, can completely reinvigorate a set of clubs. It doesn’t have to be an expensive endeavor, and it’s one of the easiest club repairs you can do at home as long as you have a few simple tools and some time.

Most grip manufacturers have a variety of colors to choose from, with one of the newest being Golf Pride’s new MMC Teams line of grips featuring 15 different color options.

From a club building perspective, you used to have to be cautious about mixing and matching colored grips because they could vary in weight by up to 5 grams because of added dies but the Golf Pride MMC team grips all come in at 50g in standard size so you can mix and match colors to your heart’s content.

Stamps & Paint Fill

For the simplicity of the tools required to stamp clubs, you will need some potential practice (old wedges are great for this) or some serious confidence to pull this off for the first time.

Stamping is an easy way, once you get the hang of it, to customize your clubs and have a lot of fun along the way trying to come up with silly things to stamp—I often go with movie quotes.

Stamps and small anvils can be found at hardware stores, my go-to stamp set is this: Lee Valley letter & number stamp set.

Custom Ferrules

Of all the ways to customize clubs at home, this one takes a bit of club building knowhow and some proper tools but similar to stamping once you get the hang of it you can make pretty quick work of a set.

The most popular, highest quality, and coolest by far come from BB&F (Boyd Blade & Ferrule Co.) and they have an ever-evolving palette to choose from. If you can do this job yourself, it is an inexpensive way to seriously jazz up any set, but if you are getting them done by a club builder, you can expect to pay a premium since the installation process involves complete disassembly—as shown in the video below.

Whats in the Bag

WITB GolfWRX Members Edition: PixlPutterman



Recently we put out the call for our members to submit their WITBs in our forum to be featured on the GolfWRX front page. Since then, our members have been responding in numbers!

Now it’s time to take a look at the bag of WRX member: ‘PixlPutterman’

*Full details on the submission process can be found here, and you can submit your WITB in this forum thread once our forums are back to normal.*

Member: PixlPutterman

Handicap: 6


Driver: Taylormade Original One Mini (9.5-degrees)
Shaft: True Temper Dynamic Gold x100

“I have always loved smaller head drivers and usually bagged a 983k x100 combo. Had tried all the minis but they went too high….not a problem any more the TaylorMade Original One Mini. Tried a few graphite but just didn’t feel as good as my trusty x100. Playing at 9.5-degrees, 42.75”-nice mid trajectory with low spin.”

Utility iron: Mizuno MP Fli Hi (18-degrees, 23-degrees)
Shafta: KBS C Taper 125, KBS C Taper 120

“I don’t play woods, never hit them well, surely never better than my driver. I’m plenty long with my 2 iron, so it’s a great tee club. Just don’t find myself needing to go for anything “260 out”…the reward just isn’t there for the risk…

I’ve had these for ten years. The 2 iron has been bent down to 15 degrees and then back to 18 a few times. Few different shafts too but I’ve settled into the C Tapers a few seasons ago and have been happy.”

Irons: Srixon z765 (5), Wilson Staff FG62 (6-PW)
Shafta: True Temper Dynamic Gold S300 (Hard Stepped)

“I’ve never been the biggest 5 iron fan, probably because the Flu Hi 4 is so easy to hit….bought a z765 head on a whim to try a V sole and it’s been great since.”

“Playing 6-PW of the Wilson FG62…these are just butter. Hard stepped S300.”

Wedges: TaylorMade HiToe (52,56,62-degrees)

“Wedges, you know ’em, you love ’em. Wanted a low bounce 56 and a high bounce 62, so I bent a 58 and a 60, boom just want I need.”

Putter: Scotty Cameron Newport Oil Can

“I like 320-330g heads so this should be in the bag for a long time since everything new is a lot heavier. I’ll never not use a P2 Aware, just feels perfect in the hands.”

Putter Grip: P2 Aware

Ball: 2016 Nike RZN Platinum
