Review by GolfWRX Editor Chisag

With their thin topline and minimal offset, the MP59’s are one of the best looking irons in the address position on the market, if you like the look of a traditional muscle back blade. They are very forgiving of slight mishits. The sole glides through the turf and trajectory control is outstanding. Suggested index range of +2 to 13 make them an iron for a wide range of players.

If your miss is a thin shot and you prefer a reassuringly thick topline and generous offset, you will probably not appreciate the MP59’s. With a 46* PW, lofts may be a little strong for a players iron. Other than that it is difficult to find any con’s with these irons!

A softer forged feel as opposed to a clicky feel, for anyone that loves the beauty of a muscle back blade with some game improvement playability, yet all the maneuverability you have the skill to pull off. These replace my previous favorites, the MP63’s with the same look/feel and a little added forgiveness. What’s not to like? 2012 GolfWRX Editors Choice & Community Choice award winner!

Stunning. The shape of the MP59’s is prefect to my eye. From the beautiful tear drop shaped pw to the transitional 8 iron and on to the 4 iron. As an old school player, I love a thin topline and minimal offset. I strengthened mine by 1* and the offset was reduced even further. The hosel transition is also blended perfectly, with no visible hump that I find distracting. I have to admit I was not a fan of the stainless steel medallion that covered the titanium insert, but after getting used to them, it has grown on me and I actually like the look. It is very unique. The sole is narrower than the MP63’s, which surprised me a little.

The MP59’s offer the kind of control normally found in a muscle back blade. Living in Chicago, the winds are almost always a factor. Yesterday into a 20mph headwind from my normal 8 iron distance, I hit a 5 iron knockdown that never got above 20 feet and nestled about 2 feet from the pin. The aggressive sole grind allowed my 5 iron to glide through the turf and produced a very shallow divot. I did not want to ‘squeeze’ the ball resulting in normal spin and the MP59’s allowed me to put it back just a little in my stance and trap it just enough to control. Placing the ball slightly forward in my stance and trapping it, I was able to launch the same 5 iron very high riding the wind to the front fringe to a front pin at my normal 3 hybrid distance.

The standard trajectory is a little higher than my MP63’s. Yet the middle index player that loves the look and just wants to hit it high and straight will be able to play them as well. The titanium insert is responsible for much of the forgiveness. Forged into the head to give it a solid carbon steel feel, weighting is moved to the heel and toe. The only shot unaffected by the forgiveness is a thin shot that stings your hands just like a mb blade, so these are not irons for a sweeper. But shots hit a little high on the face or a little toward the heel and toe suffer very little in terms of distance or direction. These are irons that provide all the playability you have the skill to pull off. It is no wonder Luke Donald put these in his bag. But while forgiving in a good players hands, they will not help the bigger misses that the high index player is likely to make.

If you have played Mizuno MP irons, you know they feel unlike any other irons. Even with pure titanium forged into the muscle, the MP59’s have that magical Mizuno feel. 1025E Select Steel combined with Mizuno’s patented Grain Flow Forging are responsible for the legendary feel. The Primary forging shapes the head. It is aged and heated at an elevated temperature before the first precision forging that ensures the precise head shape. The second and final precision forging tightens the structure and further aligns the grain.

It produces a ball melts into the head kinda feel. Some prefer a clicky, harder feel to their forged irons and the MP59’s are certainly not that. I ordered mine with KBS Tour S-Flex shafts adding to the soft feel. Nice to know the KBS Tours are a no charge option. One nice thing about the MP59’s is you can tell when you miss it just a little as they provide enough feedback to let you know how well you are striking the ball.

I’ll admit I shyed away from the MP59’s because of the titanium insert. I already had MP63’s I was very happy with, and felt the insert would take away from the performance. I was oh so wrong. The MP59’s are what I would consider to be slightly more forgiving MP63s that interact with the turf even better.

I met Lou Cesarek for my fitting, an outstanding Mizuno Rep whom I have talked with on several occasions in the past, but I had him go through his normal routine acting as if I knew very little. It is a fascinating process when combined with the Shaft Optimizer. Just 4 or 5 swings and the rep guides you through the entire process, Lou made it seem like I was fitting myself. I am an experienced clubbuilder and built my MP63’s plus ½”, 2* upright and shafted with KBS Tour S flex soft stepped once. I did not share any of this information with Lou, but the analyzer came back with the exact same recommendations right down to soft stepped once! It was also nice to hear the Shaft Optimizer said my specs and numbers were identical to Luke Donald (with a little lower swingspeed).

So after we went through the fitting process the only thing left was to put in the custom order. Mizuno has a 2-3 day turnaround on custom orders, the fastest in the industry. If someone gets fit on a Saturday or Sunday they will have their iron set to play the next weekend. I put my order in on Tuesday and they arrived at my front door Friday morning. This was a normal order with no rush processing or special treatment. Really? I was just blown away by that turnaround.

Performance, feel, look, fitting and order/delivery speed should put the MP59’s at or near the top of a very short list. I just can’t recommend the MP59’s highly enough and will rotate them this summer with a set of AP2’s having the same specs. I have included some pictures of the MP59’s. Because they are extreme close ups, it makes the topline appear thicker than it is in person, but I wanted everyone to get a look at the perfect tear drop shape at address. I hope you enjoy them!

More Tech Specs:

The MP-59, the next generation of our award winning Ti Muscle Technology, delivers full cavity forgiveness in a player’s half cavity design. During the elaborate Grain Flow Forging process, the pure Titanium material is forged into the muscle of the MP-59 to deliver a 5% larger Sweet Area compared to the MP-58, the iron that debuted Ti Muscle Technology while taking home “Editor’s Choice” in Golf Digest’s 2010 Hot List.

The lightweight characteristics of the pure titanium allows for the ideal amount of thickness behind the impact area to deliver consistent solid feel while simultaneously providing a dramatic increase in perimeter weighting for enhanced playability.

To date, only Mizuno’s patented Grain Flow Forging process can deliver this technological advancement that produces these amazing gains in forgiveness, all within a compact, traditional head shape.

Forged Ti Muscle™ Technology delivers increased forgiveness and solid feel in a player’s head shape.
Scientifically designed to optimize sound and feel at impact utilizing modal analysis and Harmonic Impact Technology (H.I.T.).
Patented Grain Flow Forged 1025E “Pure Select” mild carbon steel and pure titanium combine to provide the ultimate soft, solid, and consistent feel.

  1. I can’t stress enough how much these irons did for my game. I played cavity backs until I could shoot 80 consistently. I was nervous switching to a players iron, but now I can work the ball in high or low, draws and fades are effortless. When I do find myself in trouble, I am able to pull off creative shots that I could not easily pull off with my cavity backs. Feedback on off-center contact is excellent, but off-center hits are not rewarded. There is some forgiveness, but expect to lose 20+ yards on mishits. Striking a pure shot is the best feeling in the world; the feel is crisp and light, the ball explodes off of the face. I get the feeling of a surgeon when I am locked in. Very precise tools from Mizuno.

  2. Went from the Titleist 690’s I had hit for years got these for Christmas and love them… they feel like butter… the ball jumps off the club with ease… I can go harder if I need with the confidence that I will pull the shot off… game changer for sure…. and it doesn’t hurt that they look great.. couldn’t be happier…

  3. Got these last June to compare with my mp 32’s of 5 years. Standard spec on 32’s, +.50, 2* up on 59’s. S300 on both. These are a big deal for me and took a couple or more rounds to dial in. Hotter off the face than the 32’s, maybe a little higher launch, maybe half club longer, but still soft Mizuno feel. They are surprisingly durable showing no wear considering I play almost everyday in season. I can hit the 4 iron way high or flatten it out for more roll. These are easy to work both ways. The stock DG s300 shaft seems to fit me well. Bottom line… there is a lot of good equipment out there but my money buys Mizuno irons. They’re that good. Man those 64’s look sick!!! Maybe 7,8,9,P

    • To know how far you need to drive the ball, compare the pros yard drive with yours.John Daly’s top shot 414 yardsSean Fister 406 yardsTiger Woods avegeras 320 yardsJason Zuback avegeras 360 yardsThe critical area to work on is your core (mid-section). Your core drives the swing and develops all the power. You’ve got to strengthen this area from a rotational standpoint to improve your driving distance.I hope that helpsGood luck

  4. Buying a set after being fitted. Tried 2 other clubs from the Mizuno range, the Nike Combo, new Adams etc and these just were the best feel and gave me the best results in backspin, side spin, distance and spread of shots. May not suit everyone so go and get fitted.

  5. Dumped my Titleist AP2 712s and picked up the MP 59s this afternoon after hitting them on the range for 4 days. Its all about the feel…with no effort the distance and direction is unbelievably consistent. I’ll keep you posted when I play my first round with them Friday. I’m predicting a 4 to 5 stroke improvement in my handicap…I’ll keep you posted.

  6. I’m a 3 right now and usually play between a 3-5 handicap and was playing Callaway X-22 tours before switching to these. After about 4 rounds with these irons I was sold.

    They’re as forgiving as my tours and the feel is like night and day!

  7. Loving mine for the last month-got custom fit on the launch monitor at Golfsmith. No wonder Luke Donald, probably the best iron player in the world has them in play!!!..

  8. So I just got my MP59’s in the other day, let me first say I did alot of research before buying and have never even owned Mizuno anything in my life and actually wanted the AP2’s to win the contest, but these things blew everything away!!!! I was astonished..I laughed and read somewhere that after each swing you feel like smoking a cig, funny but true…I got mine in standard length, 2 degrees upright, fitted with the TT Dynalite Gold XP S300’s very lively shaft and I tried about six other shafts the DNA gizmo told me either the XP’s or Project X. The project x felt like a 2×4 yuuck!!! also tried KBS not too bad but Dynalite was perfect launches mid to high but I liked the flight…Anyway, I say all this to say, you know you read about these reviews and guys say first day out shot some crazy score and your like yeah whatever,,,folks I am hear to speak the truth and nothing but the truth and like I said never even hit Mizuno gear before,,,I took them to the range on monday for about an hour or so, was turning them over like it was nothing beautiful soft draws and easy fades on demand, next day straight to the course shot a 38 on the front and a 36 on back a 74 I was like seriously!! Guys I normaly shoot in the mid 80’s these things were lasers!!!!! pure confidence and to think I was always intimidated by Mizunos…Bottom line they got it right with this model…..I am hooked!!!

  9. Demo’d these MP-59s with 300 shafts the other day. Great set-up straight off the clubshop floor. I’ve been playing Titleist 681’s for about 10 years now, and Wilson FG-17 ProStaff blades for about 10 years before that. I wear ‘em out before I invest in new clubs. These MP59s are much easier to hit than traditional muscle backs. More forgiveness, but still correct top thin line and offset. Perfect first blade for someone stepping up from GI’s, or someone (like me) who has traditionally played blades, but has a demanding day job. I think this will be my set-up for the next 5 or 10 years. I can no longer turn my 3 and 4 iron effectively like I used to, but these were a little more workable than my 681’s. Here’s the new projected set-up: MP-59 5-9, with my trusty Titleist ZB pitching wedge, Mizuno MP-11 56 and 60, a couple hybrids I can turn (including rescue), my RBZ 3 Wood and Driver, plus my TM spider ghost putter (love that waffle iron!). That set-up should get me to 50 with a decent game.

  10. Have had MP 59’s for about five months now.
    Just love them. They are about one club longer than the ap’s they replaced.
    The only negative is that the seven iron shaft has lost all it’s crome from the club head to about 8 inches up the shaft.
    These are the np 95 shafts.
    Anyone else having this problem?

  11. I’ve had my MP-59 irons for a bit less than two months. I’m hitting more greens and my USGA Handicap Index has gone from 12 to 10…the trend is down! I was tested and custom fit using the Mizuno gizmo that attaches to the shaft when you swing. I was fitted with NP Pro 95 stiff flex shafts and my irons are 1 degree upright. I love the look and I love the results. My set is 4-PW. I added three Mizuno wedges.

  12. I have played, mp 60, mp 63, mp 68 and mp,59 all with DG x100 shafts, I play of a 1 handicap . Was a 4 handicap for 8 yrs. mizuno are all great, and to me the MP 63 is the best of the lot, 59 are great but I cannot say they are exceptional. I recently bought a set of Miura 202 CB irons with DGTT x100 shafts, in 3 weeks I drop 3 shots. They are very much the same feel as Mizuno but the shape of the club, the sole and consistancy is something I have not experienced before. Yes they are expensive, but worth the money, but to me Mizuno is a great brand and have the top clubs for every handicap level.

  13. Played my first round with my Mizuno MP59s today and I am very pleased with them… I am coming from MP62s, the 59s feel more responsive and more forgiving than the 62s while keeping all the player type iron attributes. I also like the compact head size in the short irons compared to the 62s.

    Very happy with the 59s, they will be my gamers until I wear them out.

  14. Just bought the mp 59’s at golf town. Have played 3 rounds with them. They are even better than any of the reviews claim them to be!! I’m a 10 hndcp and my confidence increases with every swing of these babies. The guys at Mizuno have nearly perfected the acoustics and feel. Both are soft but yet powerful. Even mishit shots carry a ridiculous distance. I paid $1000 for these bad boys and would have gladly paid double.
