Mizuno JPX 921 Hot Metal (4-PW) Graphite Irons


JPX 921 Hot Metal has been developed with more forgiving features and now with even more length. It is made of a material called Chromoly, which makes it extremely thin for maximum ball speed without making the club feeli hard. The face is designed to deliver maximum ball speeds even in bad ball hits.

Chromoly 4140M: Mizuno’s 3rd generation of designing and manufacturing irons using Chromoly – now taken to its limits. A re-engineered CORTECH face, now 0.2mm thinner across the center 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 patterns dictated 3 additional sound ribs, producing a more solid sensation.

Pearl Brush Finish: Anti-glare to minimize distractions over the ball.

Stability Frame: Additional perimeter weighting with toe bias for stability from off-center strikes.
