Based on photos from Mizuno, the irons will be Grain-Flow (GF) Forged from 1025E carbon steel. Also, based on comments from the company on Facebook, the irons will have more redistributed weight from previous MP models.

    Miz sculptured, re-sculptured and then re-re-sculptured in 2015. What’s next? Scotch Blades?

    Mizzens are nice clubs and as a club maker and repairman you get to know what is quality and Mizunos are quality clubs and are made right. I had a set years ago and liked them a lot. Then I went on the TM staff for a few years. I just retired and bought some Hot Metals, very nice, good quality and a good club for us Seniors. Love em.

    Comment: I have been playing Mizuno irons since 1995. Started with 29s then 33s then 52s then 67s then 58s then 69s then 4s and now 5s. All the irons have been great, I originally replaced my Hogan PCs with the 29s because of superior feel, accuracy and distance versus the Hogan PCs ( realizing that the PCs had the smallest sweet spot of any Hogan iron)

    The MP5s are by far the easiest to hit and best feeling Mizuno irons that I have ever played. The 4s are very close to the 5s but not as forgiving. I think the KBS shafts also add to the feel and playability. I also continue to play my MP33 1-iron with an Aldila graphite shaft. The thicker top line and wider sole is not an issue. They are still a beautiful set of blades.

    Ya know I’m kinda thinking I might like these ..I’ve had most of the mizzy blade line since the 29’s ..14’s,33’s,37’s,68’s and the Mp-4’s ..then Miura tournament blades and two sets Miura 1957 Baby Blades.. now I’m not sure how these are going to feel because they are supposed to be somewhat hollow’ish ..was really never a big fan of that ..I think the Mp-4 is somewhat the same way ..hollow’ish..the Mp-4 still felt really nice but nothing like the 14’s when flushed..the Mp-5 is supposed to still have the great Mizuno feel but with technology built in .. Wider camber/sole : a far cry from the Baby blades : .. Weight taken out of the middle and placed on the muscle pad ” low on the 3i higher on the P wedge muscle pad wise..and some weight added to the top line that would come in handy if you ground load a little heavy and take the ball off the top so there’s still some meat behind the ball ..I was a +3 years ago on the mini tours when I played the baby blades and now a non competitive low single but just can’t get away from blades ..I think these “helper blades” might get it for me , they look outstanding ..they look every bit a blade/with a technological edge.. Still love taking my 14’s out for a crack but missing them just enough to not break par I have some rounds 68’s with my 714 ap2’s ..a great club as well but miles away from that Mizzy feel..and like I said I just feel better behind a blades ..I don’t really compete anymore so now it’s just about having a great time with the guys ..would be great if these Mp-5’s gave me a little more help to miss a little better ..either way can’t wait to bagg’em!

    Agreed: top lines are huge as are the soles w/o closer inspection. Like the finish and muscle shape. Maybe the performance results will mitigate the above negatives?

    I will always probably be mizuno biased, but still waiting for a 64 direct replacement

    Let me rephrase: that top line is too flat and way too thick.

    Top line is too thick.

    Good to see Mizuno getting back to their roots…of ripping off Hogan’s designs!

    Great looking blades as all Mizuno’s are. What’s the purpose of the channel though?

    What’s the “channel” part? That vague shaping on the back of the iron? I think of “channel backs” as having a significant undercut. Many will remember the fascination with the old Titleist 690.CH. That was the ultra-rare Japan-only set for which the 3-iron found its way into Ernie Els’ bag and became his go-to utility iron.

    Mizuno (always creating some of the most beautiful irons in the game) has plenty of its own experience with true undercut channel backs. The MX-25 and MP-53 come to mind. There are many more I am sure; almost too many to think of. Are they doing something more “channel-ish” in the long irons?

      Not that kind of channel. Just a wave-y scoop out near the top half of the head, to distribute weight lower to the muscle. No slots, no cut outs, not that kind of channel.
