Shot-making Pure Precision - Exemplified
The latest quality forging from Mizuno and their golf engineers is the highly-anticipated MP-4. The new MP-4 is simply stunning with its classic shape and understated graphics that traditionalists will find elegantly flash-free. And, according to Chuck Couch, vice president of golf product for Mizuno, these new Mizuno irons feel as good if not better than any iron Mizuno has ever produced.
The Mizuno MP-4 is the purest of forged muscle backs, with a noticeably smaller face at ball address, and is for shot-makers seeking the ultimate control over their ball flight. On most irons the blade length of the iron gets longer as the club gets shorter. The MP-4 bucks that and instead of increasing blade length, Mizuno engineers added weight to the MP-4 irons by increasing the size of the muscle pad behind the sweetspot of the irons, which is the reason for the irons’ pronounced bulge, or “Pure Muscle,” in the back. The muscle bulge is most prominent (go ahead, stare, it's okay) in the scoring irons and reduces down through to the slender long irons – where design emphasis is placed on creating a quick launch and steeper landing angle. According to Mizuno and their design staff, the added mass amplifies the MP-4’s “Harmonic Number,” which are the frequencies created at impact that golfers equate with feel. That added mass gives these irons a pleasing “sticky, soft feel” at impact that provide a feel and sound about which golfers will rave.
These irons are not for everybody though due to their CAD designed final profile and exacting nature. But, “the Mizuno MP-4 gives real shot-makers the ultimate control over their ball flight – with the very purest feel and feedback possible. If you want to learn to become a truly great shotmaker, the MP-4 is the best teacher you can have” states Tetsuya Kanayama, Mizuno’s Manager in club development.

Mizuno MP-4 Forged Irons Expert Review
Written By: Bob Gomavitz
This pure muscle back design is a grain flow forged from 1025E pure select mild carbon steel billet to enhance the feel that Mizuno is famous for. The muscle back design incorporates a Variable Muscle Bulge which puts more of a bulge on the short irons for trajectory control. The thin top line and a reduced offset finish off this timeless piece of art.
Who's It For?
Players irons are for touring and club pros, skilled amateurs and traditionalists. While they offer the greatest feel and maneuverability, with a smaller sweet spot than game improvement irons they are also the toughest to hit consistently.
First and foremost, the Mizuno MP-4 is what comes to mind when you hear muscle back irons. Mizuno has been a leader in the forged iron market for years, and will always be there. The MP-4 head is the club that make all types of player giddy with excitement, which I saw first hand when testing it. Its like a magnet for people when they were looking at the clubs I was testing. Personally, beyond the glamor, I saw tradition in my hands with its compact, clean lines. These irons have an excellent shape, the round toe transitions nicely into a thin top line. A soft neck line from the hosel leading into the top line gives a less offset look. Feel-wise, the MP-4s are super solid. Many swear that these irons are the best feeling irons made and I tend to agree. Shot-wise I had some issues of slightly thin shots, which felt a bit clunky as they should. My dispersion was top notch even when I bottom grooved it, and the ball flight was plenty high enough, consistently landing softly.
