Mizuno unveils new MP-54 irons

By Jonathan Wall, PGATOUR.COM Equipment Insider

Mizuno created some considerable buzz during Open Championship week when it released several photos of the new MP-4 and MP-54 irons on its Facebook page. On Wednesday, the company tweeted out a video that officially pulled back the curtain on the MP-54, and some of the performance benefits behind the new forged cavity back iron. 

Forged from 1025E Carbon Steel, that produces a soft feel and consistent feedback throughout the entire set, the new MP-54 is being touted as a traditional players iron — Charles Howell III tests them out during the clip — with a new "Step Muscle" design.

"At address, you're getting something that's somewhat classical, somewhat traditional," David Llewellyn, Mizuno's manager of golf club development, said in the video. "But the way we designed the cavity back, it's not just a cavity back. We're actually milling a pocket cavity, which frees up discretionary weight for us. So even though it has the milled pocket cavity to make it more forgiving, you still have an awful lot of thickness behind impact."

The "Step Muscle" design improves the launch angle and feel through the mid- and long-irons, thanks in large part to a milled pocket cavity in the back of the mid- and long irons that's thicker in the lower section of the face.

As far as MP-4 is concerned, Mizuno Golf Europe released a video recently detailing the new iron, which has a forged muscleback that varies in thickness to improve the playability of the longer irons. The peak of the muscleback was also moved higher up the back of the iron to improve feel.

Mizuno's MP-54 and MP-4 irons will both be available Sept. 9 and will retail for $1,000.
