Mizuno JPX921 Hot Metal 



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."

Hot Metal

Brett did the fitting. I needed a higher launch, fix my right side misses (pulls) and wanted graphite shafts. These clubs did both and as a bonus, the graphite shafts were available.
My misses are narrower, and even my 5-iron stops within 15 feet of landing on the green. The graphite shafts are appealing, they look good without standing out like some shafts.
I am very pleased with these irons. They have a very nice weight, swings easy, and are really appealing to look at. Nice feel and sound at impact. In addition, the sunlight does not reflect back into my eyes with the higher lofted heads.

Fast Delivery

Site says 6 to 7 weeks before delivery. I got my set in 2.5 weeks. very surprised at how fast it was.
Packaged very secure. Have not hit them yet as it is now winter but I will take them to a golf
simulator to try them out before going out on the course in the spring.
