Mizuno MP-58 Iron Review

When it comes to game enhancement (players’ irons) few companies have the following that Mizuno Golf has and with the release of their new for 2010 line of irons, The Hackers Paradise feels as if we know why. THP got a sneak preview of the new irons late last year just before release when they were featured in our THP: The Magazine round up of irons and our testers came away pretty impressed. For the purpose of our testing we wanted to take the time in this review to expand a little bit with on course playing and be able to show off the new irons for those that missed out on the sold out magazine issue.

From The Company
Introducing the new MP-58 irons with revolutionary DUAL MUSCLE TITANIUM Technology! During the complex Grain Flow Forging process, a high-tech Titanium metal is forged into the outer muscle of the iron, which not only delivers the feel, workability and shape every MP player desires, but also takes playability in an MP iron to a whole new technological level. The light weight characteristics of the pure Titanium utilized in the MP-58s allow for an ideal amount of thickness behind the impact area to ensure the legendary soft, solid and consistent feel one expects from a Mizuno iron, while simultaneously providing a dramatic increase in perimeter weighting for enhanced playability. The MP-58 irons achieve the rare combination of a penetrating ball flight, increased MOI, and superior feel, all in the ultimate player’s head shape.

Dual Muscle TITANIUM design combines multiple materials during the Grain Flow Forging process to deliver solid feel and amazing playability.

Impact, sound, and feel are optimized through extensive utilization of Modal Analysis, which separates Mizuno irons from the competition.

Patented Grain Flow Forged 1025E “Pure Select” mild carbon steel and pure Titanium combine to provide the ultimate soft, solid, consistent feel.

Durable double nickel chrome plated finish and a Black Chrome stainless steel muscle medallion provide elegant aesthetics.

Modified U-grooves, which conform to the Condition of competition 2010, produce the ideal spin rate for maximum playability in all conditions.

Rolled leading edge, flattened mid-sole, and rolled trailing edge deliver consistent striking ability from all types of lies.

First Impression & Looks
Mizuno came to play with this set when it pertains to the aesthetics of these irons. Simple, Classic, Elegant, and Striking are all the terms that our testers used when they first put their eyes on the new set. Smaller head design and quiet graphics talk to you rather than scream at you and the subtle, but classy look instills confidence like few irons on the marketplace can right now. In the bag they show a sophistication that few have and at setup they are begging to be worked all over the course. When it comes to describing them for me, only one word comes to mind and that is CLASSY!

Range Testing
We were able to have 9 golfers test the Mizuno MP-58 irons over the course of 2 days on our range and not a single person did not fall in love with them. All 9 of our golfers were lower handicap players (sub 10 index), and that certainly played a role in the outcome. The MP-58 is not geared towards the game improvement crowd, Mizuno has plenty in their lineup to help in those situations like the Mizuno MX-200 or the Mizuno MX-300, both of which we reviewed already. However almost all of our testing panel did remark on the forgiveness that was packed into these beauties. Do not be fooled by the traditional look, for a lower handicap player that is looking for a touch more forgiveness, Mizuno has arrived to deliver what some were calling the ultimate golf club!

Testers took turns hitting balls for approximately 2 hours and one of the drills was to work on shaping the shots they were hitting. We wanted each golfer to hit them straight, fade, draw, high, and low and see what kind of response they were getting. One word can be used to describe the ball movement performance and that was “Outstanding”! But something else stuck out during this drill and that was just how much forgiveness was in the irons, particularly off near to the toe of the club. When missing high on the club face or off the heel side of the iron, the forgiveness was okay, but not great. Pretty much what you expect for a game enhancement iron at this level. Miss the shot off of the toe with the MP-58 and we saw a much larger amount of mis-hits that still flew straight. The feedback given through your hands was phenomenal and when it came down to it, the testers involved felt as though Mizuno has a true gem on their hands with this set.

Course Testing
I was able to put the Mizuno MP-58 irons in my bag for 8 rounds of golf and came away extremely impressed. The set came setup with 3-PW and were shafted with DG S300 shafts. While I prefer other shafts on the market, this has become a gold standard for many iron sets and combined with this club head is a perfect marriage of feedback, ball flight, and control. Looking at the iron set coming out of the top of your bag as you get ready to hit your next shot is truly a joy, because as mentioned previously, these are simply gorgeous looking clubs. They inspire confidence that you can really do whatever you want to do with the golf ball. I had no issues moving the ball all around the course in terms of ball flight and become a huge fan of the nice controlled cut that my natural swing was producing with these.

The feel is what you should come to expect from a players iron of this caliber. Soft, smooth, and buttery are all terms that are thrown around a lot and the Mizuno MP-58 irons live up to the hype of all the descriptions out there. I was surprised at the amount of forgiveness was packed into the irons, especially off the toe, which was previously mentioned. The ball flight is a thing of beauty, with a slightly higher ball flight than the previous Mizuno blade offerings, but definitely not too high. After the rounds were completed and these were pulled out of my bag, playing anything else seemed “off”.
In my opinion, Mizuno took a huge risk with the MP-58 and it has paid off 100%. A company known for their forging from a single billet of steel has gone away from that to add multi-material technology in the way of a titanium insert. With the process Mizuno has used to bond the two together, we found very little if any loss in feel, however the forgiveness you will gain is a tremendous asset. Could this be the ultimate combination? Time will tell, but some of our testers felt like the MP-58s were the purest combination of looks, feel, performance, and forgiveness in a game enhancement iron that they have ever tried. The Mizuno MP-58 irons have a retail price of around $999 and if you are looking for “players’ irons” these should definitely be on your short list of sets to try.
