Custom Mizuno Pro S-1 Irons

Legacy Reborn

The Mizuno Pro S-1 irons embody the purest expression of precision, feel, and tradition. Forged in Hiroshima, Japan using Mizuno’s Grain Flow Forged HD process and a single billet of 1025E Pure Select Mild Carbon Steel, these muscle back blades deliver the legendary soft feel Mizuno is celebrated for. A copper underlay refines vibration patterns, ensuring each strike provides the purest and most rewarding feedback possible.

Copper Underlay

Enhances Mizuno’s renowned feel by subtly tuning vibration patterns for superior feedback and precision control.
