I have for auction a set of Mizuno MP-53 irons, P-5 and the 3 iron. There is no 4 iron. The shafts are steel, Dynamic Gold S300 with new Wedge Brothers grips. These irons play every bit as well as when they were brand new! The heads show some dings from bag chatter with the 8 iron showing the most wear on the face. These irons are standard length.  All have lots of life and many great shots left to be played!
