Spotted: Mizuno MP-25 irons
On Tuesday, Mizuno released photos of new MP-25 cavity back-style irons on its Open Championship blog, following a Monday release of “MP-5 Channelback” blade-style irons.
The MP-25 irons are stamped “GF Forged 1025 Boron,” which likely means they’re Grain-Flow forged using 1025 Boron, the same material used in Mizuno’s JPX-850 Forged irons.
See what GolfWRX members are saying about Mizuno’s new MP-25 irons here.
This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.
Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.
Bud Cauley had >14 clubs in his bag when photographed prior to the Memorial Tournament.

- macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”

Wow, these just look powerful. Mizuno has been sending its new irons to the gym. I like the slot insert. Hoping they will be forgiving like Pings but feel like Mizzies.

Will they carry it in left hand, or will I be yet again disappointed with the release of another Mizuno line that apparently can’t make enough money selling right-handed sets to justify making the dies and molds for left-handed sets?

I could make these look so good with just a tiny amount of nail polish….

now you are talking. would love to see the face and the top line.

For those concerned about the finish of the irons (wow, really prima donna’s) you can search online for keywords “Mizuno, Yoro, custom finish” and you’ll have your choice of finish and paint fill. Almost all manufacturers are doing this now. Black finished MP4 blades in gloss or flat anyone? Yup.

Would this be their replacement of 64? Would like to see a side by side. 15 looked like a 64/59, this looks like a 64/15 minus the insert…just like to see the sole and top line in comparison to the others

Why do mizuno release so many new models per year that quite frankly, all look the same, but no one hates on them like they do other brands with yearly release cycles. I’ve never found a mizuno I liked yet, too chunky, even the blades.
Dr Troy
Jul 15, 2015 at 10:56 am
even MP 4’s too chunky? Damn man. You like the butter knife eh? 🙂
Mike
Jul 16, 2015 at 7:19 am
yep. MP4 have a long blade and thick for a blade top line IMO

Jul 15, 2015 at 11:34 am
You answered your own question there Mike. The difference is annual release cycle vs. quarterly/monthly release cycle.

These look really nice. Anyone know the optimal handicap range for these?

I love Mizunos.I own multiple sets of irons and a decade’s worth of wedges and hybrids. While I greatly appreciate the elimination of garish paint fill, I find it hard to believe that these irons are MPs. The bulbous nature of these irons reminds me of any number of max game improvement irons.

Yeah. Until you see its size.

Exactly. Until you see the size.

They look very much like my MP-54’s. I went to the JPX-850 forged with Boron because of better distances. If the 54’s would have had boron I might have stayed with them.

Absolutely beautiful. Mizuno definitely understands how to design good-looking irons.

lots of unhappy people about this i’m sure, complaints have been made about the feel of the forged Boron.
random guy
Jul 14, 2015 at 12:26 pm
yeah, but PING says there is no difference between forged and cast in terms of “feel.”
Surely nobody can tell the difference between different forged metals?!?!

I think the point of jeff was about the boron material rather than the fact that they are forged heads.
The boron material if i recall correctly is harder so it allows to produce a thin face, but the feel is different because of that hardness.

Your a boron if you can’t get behind these clubs

I gather, after seeing the MP5 pictures and now these, that Mizuno designers are taking a cue from the GolfWRX segment of the golfing world, and are doing away with paintfill in some areas. Kind of nice, I think.

I think it looks really classy w/o all the paint on them
