Continuing the award winning success of Cut MuscleTM technology, the Mizuno product development team has developed a new muscle back iron featuring an innovative "Slender" Cut Muscle design. This new Slender Cut MuscleTM allows the player complete ball control by pin-pointing the COG inside the muscle back design. Utilizing our Grain Flow ForgingŪ and Cut MuscleTM technology, the design team was able to provide a neutral COG relative to the shaft axis and a consistent sweet spot location for exact trajectory and distance control. The cambered sole of the MP-67TM allows the player precise shot making capability from all types of lies. The MP-67TM long irons achieve a mid-high trajectory, while the scoring irons deliver a mid trajectory.

The MP-67TM offers unmatched ball control by utilizing a new "Slender" Cut MuscleTM Design to precisely position the COG from iron to iron.
