A revolution.
That’s what Mizuno says its Mizuno Pro Irons are when it comes to forging, something the club maker is recognized for throughout the golf world. Mizuno says the company’s engineers, working with its Grain Flow Forging plant in Hiroshima, Japan, have taken the forging process to the next level: “Every fraction of a millimeter and subtle curve has been meticulously considered, shaping the future of golf club technology,” the company says. The result is complex designs that have precise forging techniques, while maintaining the look and feel Mizuno is known for. “Other manufacturers have widely adopted Mizuno’s work to elevate the performance of elite player’s irons,” says David Llewellyn, Director of R&D at Mizuno. “What now sets Mizuno apart is the ability to apply precise manufacturing techniques learned at our long-standing forging plant in Hiroshima, Japan, to increasingly complex designs.”
The new forging process can be found in four versions of the Pro irons: Mizuno Pro 241, Mizuno Pro 243, and Mizuno Pro 245.
Mizuno Pro 241
A muscle back iron, and Mizuno says the aesthetics of the design were refined in the forging process, where even a millimeter on the topline of the iron can set it apart. “Working hand in hand with our forging plant for so many years allowed us to be incredibly precise in the engineering and craftsman’s stages of the Mizuno Pro 241,” Llewellyn said. A muscle back design, this is Mizuno’s go-to on tour.
Key Features
- Thinner topline
- More compact short irons
- Increased bounce angle
- Centre mass for improved feedback
- Soft copper underlay for better feel

This is an iron for the best golfers in the world who are also the most consistent. Fun to hit, but the typical golfer might want to look to something a bit for forgiving.
Mizuno Pro 243
Mizuno says this is the model that’s moved ahead the most through the forging process. The company’s engineers were able to design and bring to life an iron that was previously not possible, Mizuno says, with a thinner face that’s more compact than the previous version, but with improved performance. Long irons in the set fly further, so Mizuno has bumped the lofts on the scoring clubs.
Key Features
- Soft copper underlay for better feel
- 4120 Chromoly with Flow Microslot (4-7 iron)
- Harmonic Impact Technology for a soft muscle-back feel
- Wrap Around Sole Grind for improved turf interaction
- Exceptionally compact players’ profile
- Increased bounce angle for enhanced performance

This is still aimed at better golfers but opens up to a wider audience than the 241.
Mizuno Pro 245
A multi-piece grain flow construction, this version of the Pro irons uses tungsten weighting and multi-thickness face to open it up to more golfers. Mizuno says previously this was not possible, adding the evolution of the Grain Flow Forging process allowed it to become a reality. The company says ball speed gains were found in the 245, which is impressive considering the irons were slimmed down. This is largely attributable to the hollow body construction. Many might mistake these irons for the 241 given their appearance, the company says, despite the added technology.
Key Features
- Hollow body GFF 4135 Chromoly face and neck (2-8 iron)
- Internal Tungsten Weighting (2-7) for improved launch
- More compact partial hollow scoring irons (9-GW)
- Soft Copper Underlay for exceptional feel
- Harmonic Impact Technology for a soft muscle-back feel
- Traditional blade appearance
- Increased bounce angle for optimal turf interaction
Is It For Me?
The hollow body construction makes these irons longer and more forgiving. A great option for the better playing amateur seeking added distance but wanting the appearance of a great player’s iron.
