Introduced in 2011, the MP-59 "half-cavity" irons featured "Ti Muscle Technology," in which titanium is forged into the clubhead, increasing the sweet spot by about 5% over the MP-58. Mizuno's Grain Flow Forging process uses 1025E mild carbon steel and delivers full-cavity forgiveness in a half-cavity design.
The MP-59s were available in 3-iron (21º) through 9-iron (42º) and PW (46º) in RH and LH. The stock shaft was a True Temper Dynamic Gold S300.
Mira43 - 9/18/23 If you enjoy the look of a traditional muscle back blade, dino game the MP59's are one of the nicest looking irons in the address position on the market, thanks to their slim topline and low offset. They are extremely forgiving of little mishits.
