Mizuno
JPX921 Hot Metal Pro

Our Review:
WHAT IT DOES: The shape says better player, but the power and forgiveness will be appreciated by even the average golfer. Achieving this began with the creation of an extremely thin face—2.2 millimeters in the center and as thin as 1.9 millimeters in other spots. Another design highlight is a variable sole geometry that spreads the stress distribution at impact. Although that might sound wonky, the thin area at the leading edge serves as a hinge to transfer some of that stress to the sole and allow the face to flex even more.
WHY WE LIKE IT: The use of an ultra-strong chromoly steel allowed for a more complex face geometry. This delivers the extra yards necessary to compete in this category. Mis-hits also were addressed through toe-bias weighting to assist with shots struck in that area. One of Mizuno’s true strengths, however, is a steadfast desire to make sure the sound and feel are sublime, especially in a cast club. In this iron that meant a revision to the perimeter undercut cavity in which three extra ribs were added to support the frame for better sound and feel. A variety of shaft options are an important bonus for players seeking to further dial in their iron game.

Low-Handicapper
"There are no fake shots in terms of trajectory or curve, but you get the benefit of help on off-center hits relative to distance."
Mid-Handicapper
“Straight as a string. The shape of the head had a consistency throughout the set. The thicker topline promotes confidence at address.”
High-Handicapper
"It was jumping off the face with all the feel and sound you want in this category. Just easy to swing to get the distance you want. The trajectory is so pure and through the window every time."
