The JPX921 Hot Metal irons pair Mizuno's fastest ever ball speeds with a piercingly straight, ball flight and controllable landing angles. The 3rd generation of Mizuno irons to utilize the resilience of Chromoly - the JPX921 has the most complex face geometry to date for additional energy from the clubface. Choose the more Pro version for a more compact profile with reduced offset.


HIGHLIGHT:  The JPX921 Hot Metal is Mizuno’s 3rd generation to use Chromoly – R&D generally accept that any new technology needs 3 generations to near peak performance.   


  • Faster and faster Chromoly 4140M: Our 3rd generation of designing and manufacturing irons using Chromoly – now taken to its limits.  A re-engineered CORTECH face, is now 0.2mm thinner across the centre point. 
  • Seamless Cup Face: A new variable thickness sole design allows the leading edge to act as a hinge, resulting in greater face flex and ball speeds.
  • Harmonic Impact: Predicting vibration patters dictated 3 additional sound ribsproducing a more solid sensation.
  • Additional Hot Metal ‘Pro’ Version: More compact option with reduced offset.
  • Pearl Brush Finish: Anti-glare to minimise distractions over the ball.
  • Stability Frame: Extreme perimeter weighting with toe bias for stability from off centre strikes.


"The introduction of Chromoly was the breakthrough Mizuno needed to take a step up in ball speed. We learn more about the potential of Chromoly with each generation and push it further each time."

Awesome Irons

I did a lot of research before buying these irons, and glad I did. It's early in the year and we haven't had the best weather yet, but I am loving these irons! Even my miss hits turn out okay! Recommend anyone looking at new irons to consider these

Tim Bjorklund

Well I went to a golf simulator and these clubs are long even on miss hits. When a 60 year old can hit a 8 iron 165 yards 5 iron 210 yards these will be a game changer for me. I used the titleist 716 ap2 irons for the last few years and barely made 145 yards with my 8 iron even in the simulator. Can hardly wait till spring to get them out on the course.

I’ve played one round with my new irons but I love them already. I love the look, the feel and how hot they are off the face. The ball just goes!! Just a thumbs up about everything. Simply a work of art
