On the heels of the launch of its JPX 925 Hot Metal lineup last fall, Mizuno once again took time before adding the final pieces of the updated JPX lineup — with the JPX925 Forged and Forged Black irons.
With the JPX 925 Forged, Mizuno has redesigned its workhorse player’s distance irons to retain the iconic buttery smooth Mizuno feel the brand’s forgings are known for in a compact package, while updating the technology to bring the performance closer in line with the JPX Hot Metal irons. And for the first time, the clubs will be available in two finishes for the entire retail cycle.
Here are four things to know about the new Mizuno JPX 925 Forged irons.
1. Two-pieces are better than one
As a player’s distance iron, Mizuno has been constantly seeking to improve the COR (coefficient of restitution) of the face of the irons to boost ball speeds.
With each successive JPX 925 release, Mizuno was able to increase COR by only about two points. With JPX 925 Forged, thanks to a new CORETECH design, Mizuno was able to increase COR by 14 points.
“This is the equivalent of — had we continued on the progression we were doing before — this is, like, a 20-year jump in terms of technology,” Chris Voshall, Mizuno’s head of product, told GOLF.
Mizuno was able to make this leap by getting away from a traditional one-piece forging through which clubmakers would either mill through the cavity or sole to thin out the face. Now, Mizuno is forging the face and neck together and then wielding the backpiece, which gives them access to shape the face in ways they were unable to before.
“Before, we really only had two-dimensional access to the back of the face, because we had a milling tool that could move in the left-right direction, but you couldn’t go in and out because because of the forging constraints and that material that already lived there,” Voshall said. “So now by welding the backpiece on, and by exposing the entire face in the forging process, we can now forged it three-dimensionally.”
That has allowed designers to create Contour Ellipse Face from the JPX Hot Metal lineup in a forged product for the first time. The result is a compact iron with optimized ball speeds across the face, including off-center strikes.
Like the previous JPX 923 Forged irons, Mizuno’s Grain Flow Forged HD process is used with Chromoly 4120 for the long irons (4-7) while the short irons (8-GW) are forged from 1025E Pure Select Mild Carbon Steel, the same material from the popular Mizuno Pro line.
2. Triple Cut Sole
The JPX 925 Forged features a new tri-sole design called Triple Cut Sole, engineered to enhance turf interaction.
The irons feature a slightly beveled leading edge to make entry into the turf cleaner and easier for players while the trailing cuts away quickly to ensure a clean exit and uninterrupted ball contact.
3. Better in black
For Mizuno’s launches, timing can be an interesting logistical issue. JPX 925 Forged has actually been available in the Japanese market since the fall when it launched with the new Hot Metal lineup.
With the U.S. launch , Voshall said, the company wanted to give consumers who may already have seen the club a reason to pay attention to the release.
So, for the first time ever, Mizuno is launching a striking black finish option for JPX 925 Forged that will live on for the entire retail life cycle of the product, available in both stock and custom offerings. The black finish option is launching for both the U.S. and Asian markets at the same time.
The only other time Mizuno has released a black finish iron was for the Mizuno Pro 225 irons in a limited run in 2023.
4. Price and Availability
Mizuno JPX 925 Forged irons will be available for pre-order starting Thursday, Jan. 24, and arrive at retail two weeks later on Thursday, Feb. 6.
The satin chrome finish will cost $200 a club and come in both right- and left-handed options while the black finish will go for $215/each for right-handers only.
