Mizuno has consistently pushed the boundaries of club design with the JPX line, focusing on tooling and materials to cater to golfers seeking ball speed, distance, and forgiveness above all else. However, there is one segment of the JPX line that stands out by offering these attributes in a much different design. Today, we’re excited to discuss the highly anticipated Mizuno JPX 925 Forged irons.
In August, Mizuno launched their latest JPX irons series, the JPX 925. This release featured three models: the Hot Metal, Hot Metal HL and Hot Metal Pro, all packed with advanced technology. If you haven’t yet read our feature article on these irons, feel free to check it out here.

Mizuno’s JPX Forged line has undergone a significant speed revolution over its last two iterations. It began with the 921 Forged, Mizuno’s first full-body Chromoly forged iron. Chromoly is a strong and lightweight material that enabled the 921 model to achieve increased speed. The evolution continued with the 923 Forged, where Mizuno succeeded in making the clubface even thinner and wider, resulting in more consistent ball speeds and a clubhead that offered a lot of performance for its compact size. Now, for the new 925 Forged, Mizuno is introducing what they describe as the most dramatic performance enhancement in the history of the JPX Forged line.
The Design – Mizuno JPX 925 Forged
CORTECH Design with Contour Ellipse Face
The new JPX Forged irons, like the JPX 925 Hot Metal lineup, will feature the benefits of Mizuno’s CORETECH Design along with the innovative Contour Ellipse Face. The image below displays the face pattern showing the significant changes these faces have undergone. This new face construction allows for the highest Coefficient of Restitution (COR) and CORAREA that Mizuno has ever achieved in the history of JPX Forged irons. We have seen the positive effects of the Contour Ellipse Face in the Hot Metal range, and it is exciting to consider the potential for increased speed and improved speed retention across the face of the forged head.

Materials
When discussing the construction of the JPX Forged irons, it’s important to note that they do not feature a hollow body design. Instead, Mizuno employs a one-piece billet forging process to create these clubheads. While this set includes variations in both materials and technology, all clubheads utilize Mizuno’s Grain Flow Forged HD process.

The long and mid-irons, specifically the 4-7 irons, are forged from Chromoly 4120, a strong material with several advantages, including durability and the ability to create thinner club faces. Additionally, these irons feature the Contour Ellipse Face technology mentioned earlier.
In contrast, the scoring irons (8-GW) are crafted from 1025E Pure Select Mild Carbon Steel. This end of the bag is where golfers will experience the legendary feel associated with Mizuno’s forged clubs. Together, the entire set is designed to provide speed and forgiveness where it’s most needed while also emphasizing feel and precision for the crucial short irons.
Triple Cut Sole

We’ve all heard the saying: nothing feels quite like a Mizuno. When we discuss the unique feel of a Mizuno club, it involves more than just how the ball reacts off the clubface. While their forgings provide incredible softness and their Harmonic Impact Technology ensures a pleasant and consistent sound at impact, turf interaction is another factor to consider. Mizuno utilizes their Triple Cut Sole, which features a beveled leading edge and a sharply cut trailing edge. This design allows the clubhead to glide efficiently through the turf, ensuring a cleaner entry and smoother exit. The consistency of this sole enables the JPX 925 Forged irons to be confidently used from a wide variety of lies.
Where does it fit?
Golfers who aren’t very familiar with Mizuno’s lineup may wonder where the JPX 925 Forged irons fit in. Starting from the top of the JPX lineup, the HL model is designed for golfers who need help achieving extra initial launch. The Hot Metal is the line’s flagship, offering game-improvement features that deliver significant ball speed and distance. The Hot Metal Pro provides many of the same benefits but comes in a more compact version.
The JPX 925 Forged irons occupy a middle ground between the Mizuno Pro (MP) series and the JPX Hot Metal line. They have a smaller profile and lack the tungsten benefits found in other JPX irons. However, they provide a look akin to a player’s iron while maintaining a balance of distance, forgiveness, and the classic Mizuno feel.
Dark Side of the Forged

JPX 925 Forged comes in its traditional satin chrome finish, which will undoubtedly be a welcome sign for Mizuno fans. It’s a classic look that always looks great in the bag. But it’s not coming to the market alone. Launching alongside the Satin Chrome version is the all-new Forged Black Limited Edition, which looks sleeker and is an option for those looking to reduce glare on the course. Whereas the 925 Forged is paired with a KBS C-Taper Lite steel shaft or Mitsubishi MMT graphite shaft, the Forged Black is appropriately matched with a Dynamic Gold Mid 115 Tour Issue Gunmetal shaft.

If neither of those shafts suits your preference or swing, Mizuno offers a shaft optimizer to help determine a player’s Swing DNA. By taking just three swings, Mizuno’s software will recommend several shaft options, the ideal lie angle, and set makeup. As part of this fitting experience, the Shaft Optimizer measures various factors, including head speed, tempo, toe down, kick angle, release factor, lie angle, attack angle, and shaft lean. After analyzing this data, the software will recommend three golf shafts based on your swings. For golfers who struggle to find the perfect shaft, the Mizuno Shaft Optimizer is designed to guide you in the right direction.
Mizuno JPX 925 Forged Standard Specs

At long last, the JPX 925 iron lineup is complete! I am excited to see how the introduction of the Contour Ellipse Face will enhance performance and if the impact is as significant as seen in the Hot Metal irons. Having played two previous generations of JPX Forged irons, I look forward to experiencing the differences this new model offers.

I am TOTALLY impressed with these. They look SO good! I have the 780 SW in them and are very smooth.
Just got done with my free ‘fitting’. Forged is really really good. Almost identical ball flight but maybe 300 less spin but higher launch and peak height. I also got about 10-15 yards. 7 iron is a 165-170 carry club for me with 243. Was 175-180 with forged. I’m not sure what that will do to my gapping that I’ve got pretty much figured out right now.
I wish I had access to the data, but it was a golf galaxy thing, and apparently they couldn’t send it.
I walked away in love with the look of the black finish and feel off the face. It’s a snappier punchier than 243 but still has the unmistakable ‘Nothing feels like a Mizuno’ quality I’ve come to know and love.
I want to visit them and some other options, namely Limit3d (3DP) then make a decision in the next 2 weeks.
Ive had 3 modest range sessions where I hit PW the most. They don’t seem to wear as well as the Cobra. The face is fine but some seems to wear more. Still earlyView attachment 9325005

With the two-toned face, I don’t anticipate it being a huge issue. (Though my miss is on the toe side it’s not that far out on the toe haha)
I expect the sole to wear down a bit, that kind of wear looks pretty similar to what I see currently on a 2 year old Fli-hi..
I think I expect 925 forged to wear a little more due to the more matte finish of them compared to Fli-Hi.
Thanks for the update on that.
Has anyone done a head to head vs the 925 HotMetal Pros?
I am thinking it would be a battle of feel vs forgiveness, and then personal preference on profile. In the fitting bay, I could see myself “rooting” for the forged to win out, just to give me a valid excuse to put the black in the bag.

That would be an interesting battle, but yeah, I think it would come down to feel preference on feel for most.
