MIZUNO JPX 921 Forged 4-PW GW Iron Set with Steel Shafts

The JPX 921 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.

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.
