The making of zxi
MAKE. MEASURE. MASTER.
i-forged
The unmistakable feel of a pure strike.
That pursuit led to i-FORGED, our most advanced breakthrough in iron metallurgy. A one-of-a-kind formula that strengthens and enhances every ZXi Iron for superior feel, while supporting greater distance, forgiveness, and control.
01
Precision engineered.
The story of ZXi Irons begins with precision. Engineer Yuki Shimahara and his team approach the iron through numbers, shapes, and analysis— devising its technology, look, and performance goals.
Measuring. Modeling. Perfecting every dimension in pursuit of the ideal strike. But feel isn't perfected on a screen.
02
Hand Shaped.
As prototypes near final form, each model is refined by a master Japanese craftsman through feel and touch.
Filing. Shaping. Honing through instincts developed over decades.
Between calculation and intuition, design and touch, the Iron takes its final form.
03
Perfected on tour.
Those final prototypes then define the master molds used to forge every production head.
Then they return to the course, in the hands of our tour staff. Tested under pressure. Proven where it matters most.
Because every great Iron is measured one way: by the unmistakable feel of a pure strike.
Technology
NEXT GEN ZXI TECHNOLOGY
i-FORGED
A player's Iron with refined, tour-preferred looks, pro-level feel, and unmatched control—featuring newly refined toplines, narrow soles, shorter blade lengths, and minimal offset designed for precision playability.
MainFrame IQ
MainFrame iQ is a variable-thickness network of grooves, channels, and notches precision milled into the back of every ZXi5, ZXi5+, and ZXi Utility Iron face. At impact, these features flex together to maximize energy transfer for more speed, more consistently, across the face.
PureFrame iQ
PureFrame iQ features a wider, thicker ridge of softer 315C steel forged directly behind the sweet spot of every ZXi7 Iron. AI-assisted simulation allowed engineers to optimally expand this ridge— stiffening the impact zone, reducing face deformation, and using less mass than the previous generation for higher MOI and an irresistibly soft, remarkably stable feel.
Tour V.T. Sole
Srixon's Tour V.T. Sole takes turf interaction to a whole new level of detail with a proprietary combination of sole widths, bounce angles, and notches. This technology encourages a smooth glide through fairway, rough, and sand without losing speed, even if you enter the turf slightly behind the ball.
Refined Players Shaping
Guided by Srixon's tour staff, every new ZXi Iron has been refined for a cleaner, more exacting profile, featuring slightly thinner toplines than the previous generation.
Precision Forging by Endo
Every new ZXi Iron face and body are forged at Japan's premier forging house: Endo, the gold standard in iron forging. A place that refuses to compromise on feel.
The lineup
ZXi Irons Lineup
With a range of ZXi Irons models to suit every style and handicap, you can start with the right foundation - or blend models into a combo set. From there, every detail is yours to define, from loft and lie to shaft length, and grip.
Tour-proven components come standard, but our deep custom catalog ensures every set is finished to your exact vision.
