The Mizuno MP-59 irons features Ti Muscle Technology, which delivers full cavity forgiveness in a half cavity design. These irons undergo a Grain Flow Forging process which combines to produce the optimal blend of control and feel. Sound and feel are optimized through Modal Analysis and Harmonic Impact Technology, providing the feedback that better players demand. The lightweight characteristics of the pure titanium placed behind the hitting area allows for the ideal amount of thickness behind the impact area to deliver consistent solid feel while simultaneously providing a dramatic increase in permeter weighting for enhanced playability. The stainless steel medallian presents elegant aesthetics.
