At the core of the Mizuno Pro S-1 is Mizuno’s Grain Flow Forged HD process, carefully executed in Hiroshima, Japan. Forged from a single billet of 1025E Pure Select Mild Carbon Steel, the S-1 delivers the unmistakably soft and responsive feel through impact that Mizuno is globally known for. The inclusion of a copper underlay further optimises this experience, subtly refining vibration patterns to produce the purest, most satisfying feedback. Developed and tested with input from tour professionals, the S-1 incorporates a Channel Back Design that redistributes mass for greater vertical stability and a more consistent centre of gravity. This design works seamlessly with Mizuno’s Harmonic Impact Technology, which fine-tunes the feel by adjusting the club’s vibration frequencies to deliver even more responsive feedback.\u003c\/p\u003e\n\u003cp style=\"padding-left: 120px;\"\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Benefits:\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e Further Optimised Grain Flow Forged HD (High Density) \u003c\/strong\u003e\u003cbr\u003eThe S-1 iron is masterfully Grain Flow Forged HD from a single billet of 1025E Pure Select Mild Carbon Steel in Hiroshima, Japan—a testament to Mizuno’s heritage in precision forging.
