Continuing the award winning success of Cut Muscle technology, the Mizuno product development team has developed a new muscle back iron featuring an innovative "Slender" Cut Muscle design.  The new Slender Cut Muscle design allows the player complete ball control by pin-pointing the COG inside the muscle back design.  Utilizing Mizuno's Grain Flow Forging and Cut Muscle 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-67 allows the player precise shot making capability from all types of lies.  The MP-67 long irons achieve a mid-high trajectory, while the scoring irons deliver a mid trajectory.
