JPX921 Forged



The JPX921 Forged iron integrates the power of Chromoly into a full-body Forged iron for the very first time.  Initially applied in Mizuno's Hot Metal irons - Chromoly has made the cross over to a Mizuno's forgings with staggering results. The fastest ball speeds Mizuno has ever produced from a fully Forged iron - a treat for both the senses and the scorecard. Grain Flow Forged in Hiroshima Japan.


CONVERSATION:  Despite the all the tech, the JPX921 FORGED gets noticeably sleeker through the set and feels more like a traditional forged iron.


  • Forged in Hiroshima Japan: Grain Flow Forged HD at our legendary facility - for an identifiable and unsurpassed Mizuno feel.

FASTER. FORGED. FIRST:   Chromoly 4120 allows a clubface upto 0.5mm thinner for our fastest peak and average ball speeds from a full body Forged iron. 

  • Sleeker Compact Profile: A shorter blade length throughout, bevelled training edge and reduced offset.  
  • CNC Back Milled: A 6.4% wider back milled slot increases stability from off centre strikes – from a smaller clubhead.
  • Stability Frame: Additional perimeter weighting with toe bias for stability from off centre strikes.
  • Pearl Brush Finish: Anti-glare to minimise distractions over the ball.


"The JPX921 Forged is everything you could want from an iron - stable, incredibly fast from the face, coupled with that incredibly soft Mizuno Forged feel. I like how the slightly reduced offset and bevelled trailing edge give a sleeker, faster look to the head."

Fast Delivery, Great Product

Clubs came in 5 weeks, quoted 6-8. The sticks themselves are amazing. I am a sim owner and hadn't upgraded my clubs since 2008. +10-15y on each club, better dispersion, more spin/control... they outperform my old clubs in every single metric, and the data supports that. I am a 7h and my dad is 20h, we both got the same benefits in terms of extra distance and better control despite the fact the shaft is suited to my swing, and not his. So if your like me and using 10yo sticks, treat yourself to an upgrade, you wont regret it. Oh, and yes, nothing feels like a Mizuno!

Great experience and great irons

Clubs arrived about 3 weeks ahead of schedule. Delivered exactly as ordered, no issues. Clubs are awesome, took a few rounds to adjust from my old Mizuno's. Definitely seeing the extra length and forgiveness! Very happy.

Great Site, Good Experience

Order arrived within the projected timeframe, and accurate to the custom specifications. Only minor complaint, would be that there wasn’t any shipping information/tracking provided. I had actually sent the vendor a message inquiring as to the status, two days later the shipment arrived complete. Considering the current challenges with global logistics, I suppose this could be excused, otherwise...five stars. Within Canada, this is a great site for players searching for something other than Off The Rack gear, and I’ve recommended CPSO on a number of occasions.
