PREVIEW: Mizuno Golf JPX EZ forged irons

PREVIEW: Mizuno Golf JPX EZ forged irons

You might not be able to see the boron in Mizuno Golf's new JPX EZ forged irons, but you should be able to feel it.

Though there are only 3 parts per million of boron in the 1025E stainless steel alloy, the material that makes the clubhead is, according to Mizuno, 30 percent stronger. The presence of boron -- atomic No. 5, if you're curious -- allowed Mizuno engineers to make the clubhead bigger, which is a rarity for a forged iron, and move some of that extra weight out to the perimeter for more forgiveness. It also allowed the club face to be thinner, coming in at 1.7 mm, as opposed to something at least 50 percent thicker had boron been left out of the process.

The CNC-milled pocket cavity gets smaller through the set, disappearing after the 7-iron to make the 8-iron through wedges actual cavity-back irons, while the COR Tech design focuses on variable thickness in the longer irons and consistency across the face in the scoring clubs. The soles get wider up toward the longer irons. The soles also have beveled leading and trailing edges for better turf interaction and improve aerodynamic performance through the swing.

The center of gravity moves up the clubface through the set to help a player get the longer irons higher in the air and flying farther.

The soles of irons get progressively wider through the set and the center of gravity (CG) locations rise, too. This has been done to make the long irons easier to hit high and far, while allowing players to flight their short irons and scoring clubs lower for more control. Mizuno's Power Frame has added weight compared to prior models, offering more forgiveness in the form of better moment of inertia control on off-center hits and better feel and feedback.

The JPX EZ Forged irons will be available Sept. 18 for $1,000 in steel shafts, adding $100 for Orochi graphite shafts. Custom shafts and grips will not be extra.

The company will also offer the JPX EZ ($800 for steel, $900 for graphite), a cast iron set that sports an undercut channel beneath the topline for added springiness off the face. The JPX-EZ irons have a black nickel-plated finish and are available in 4-SW. Like the forged cousin, they're available Sept. 18.
