Mizuno JPX 921 Tour Golf Iron – Steel The Mizuno JPX 921 Tour Golf Irons in Steel are consistently Mizuno’s most chosen model on Tour among non-contracted professionals. Mizuno’s JPX921 Tour maintains its predecessor’s surprising fusion of precision with stability from off-center strikes. These Mizuno Irons are now even thicker behind impact for an enhanced, softer feel, with tour refined short irons for smoother turf interaction. Forged In Hiroshima, Japan Grain Flow Forged HD at our legendary facility from 1025E Pure Select Mild Carbon steel – for an identifiable and unsurpassed Mizuno feel. Modern Tour Flighted Mizuno’s Stability Frame with toe bias weighting gives the longer CG distance needed for a straighter, consistent ball flight. Workshop Refined Short Irons An even narrower sole to the shorter irons tested for clean turf interaction. Harmonic Impact Feel impact for a fraction longer thanks to the thicker cavity pad – evolved from Mizuno’s study of vibration patterns. Pearl Brush Finish Anti-glare to minimize distractions over the ball.
