What it does: When designing a smaller clubhead, figuring out where weight is needed and how to move it there is a big part of the puzzle. This iron features less weight in the toe than the JPX900 Tour and JPX919 Tour. The saved weight is then moved to the perimeter of the clubhead to increase forgiveness on off-centre hits and to make centre strikes feel pure by lowering the sound pressure. Mizuno has given considerable thought to the details here, like progressive sole shaping in which the longer irons have wider, weightier soles to help get the ball airborne and how the scoring clubs have narrower soles to shape shots more easily.
Why we like it: The company is legendary for its jewel-like and tour-proven forged irons, and the JPX921 Tour only enhances that reputation. A compact, muscle-cavity blade forged from 1025E carbon steel, it’s sure to attract attention from those at the top of the skill pyramid. However, suggesting this iron is just another solid exercise in metallurgy would be a tad unfair. Mizuno also studied vibration patterns to develop a thicker cavity pad that lets players feel impact for a fraction longer.

“A home-run look. It has some offset, but you don’t see it. A compact head, without looking tiny. They’re true. At contact, I could predict the ball flight.”
