If you live for pure ballstriking, Mizuno’s new Pro S-1 irons are built for you. From the first swing, they deliver the kind of feel, feedback, and control that experienced players appreciate. Clean lines, forged construction, and tour-informed shaping make this a blade that rewards precision without overcomplicating things. Now available at Worldwide Golf, the S-1 is ready for golfers who value craft and performance in equal measure.

Forged in Hiroshima, Tuned for Feedback

At the center of the Mizuno Pro S-1 experience is Mizuno’s Grain Flow Forged HD process, performed in Hiroshima, Japan. Each head is crafted from a single billet of 1025E Pure Select Mild Carbon Steel, delivering that signature Mizuno softness and clarity through impact. A layer of copper beneath the chrome takes things a step further, refining vibration patterns to produce that rare, unmistakable sensation when you catch it flush.

Channel Back Muscle: Stability Without Sacrifice

While the S-1 irons stay true to the blade profile, a new Channel Back Design adds subtle performance benefits. Mass is redistributed behind the face to help stabilize vertical launch while maintaining a pure, clean feel. The result is a touch more consistency and forgiveness – especially in the long irons – without muting the shotmaker’s connection to the clubface.

Tour-Tested Sole for Crisp Turf Interaction

Player feedback from the professional ranks shaped the sole design. Mizuno reduced the camber height, sharpened the leading edge, and added bounce – all to help the club glide more easily through the turf. For players with shallower swings or those who take tight, efficient divots, the design change makes a meaningful difference in how the club behaves at impact.

Satin Finish, Serious Focus

The Soft White Satin finish looks clean and understated in the bag but shines where it matters most – at address. Its anti-glare treatment helps keep focus on the shot, making it easier to dial in under all types of course conditions.

A Blade for the Purist – Refined, Not Reinvented

Everything about the Mizuno Pro S-1 irons reflects a commitment to shotmaking. There are no distractions, no tech gimmicks, just a beautifully forged head that rewards skill and precision. It’s the kind of club that makes you want to practice more and rewards those who do.
