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.
OVERALL BOTTOM LINE:
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.
