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.


Why are they 4-PW, GW?:  Mizuno’s tour audits in 2019 showed not a single JPX919 #3 iron in play.  Hence the JPX921 Forged is 4-GW, encouraging the MP-20 HMB to fill the #3 iron slot.


  • 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." CHRIS VOSHALL / PRODUCT MANAGER, MIZUNO
