Looks/Impression
The first thing that strikes you about the MP-20 MB irons is how beautiful they look. They have a classic Mizuno style that blends elegance and simplicity. They have minimal branding and graphics on the back of the club, which gives them a clean appearance. The copper underlay adds a subtle touch of warmth and richness to the chrome finish.
At address, the MP-20 MB irons look like true blades, but with a touch of refinement. They have a thin top line that is not too sharp or rounded, and a minimal offset that is not too noticeable.
The head shape is compact but not too small, and you can see the entire blade behind the ball. The satin finish is also very attractive and reduces glare and enhances durability.
Overall, the MP-20 MB irons are very pleasing to the eye and inspire confidence at address. They look like they belong in the hands of skilled players who appreciate quality and craftsmanship.
Key Features/Technologies
The MP-20 MB irons have few features and technologies that make them stand out from other irons in their category. Here are some of them:
Grain Flow Forged HD
The MP-20 MB irons are forged from a single billet of 1025E mild carbon steel using Mizuno’s patented Grain Flow Forging process. This process ensures that the grain structure of the steel is aligned along the club face for optimal strength and consistency. It also enhances the feel and feedback at impact by reducing vibrations.
Copper Underlay
The MP-20 MB irons have a thin layer of copper underlay between the steel face and body, which adds softness and feedback to the feel at impact. The copper layer also helps reduce vibrations and enhance sound quality.
Harmonic Impact Technology (HIT)
The MP-20 MB irons have a patented technology called HIT, which is a process of fine-tuning the sound and feel of each iron by using computer simulations and acoustic measurements. The result is a more satisfying and consistent sound and feel across the set.
Standard Stocks/Specs
The MP-20 MB irons come in a standard set of 3 to PW, with optional 2 iron available. The standard shaft options are the True Temper Dynamic Gold S300 steel shaft or the KBS Tour C-Taper Lite 110 steel shaft. The standard grip is the Golf Pride Z-Grip Full Cord.
The MP-20 MB irons have standard lofts that are slightly weaker than some other modern irons. They also have standard lengths and swing weights that are slightly heavier than some other modern irons. Here are the standard specs for the MP-20 MB irons:
| Club | Loft | Lie | Length | Swing Weight |
|---|---|---|---|---|
| 2 | 18° | 59° | 39.25″ | D3 |
| 3 | 21° | 59.5° | 38.75″ | D3 |
| 4 | 24° | 60° | 38.25″ | D3 |

Performance
The MP-20 MB irons deliver on their promise of providing the purest and most traditional feel and performance of Mizuno blades. They are precise, consistent, and responsive, but they also require a high level of skill and consistency to hit well.
Forgiveness
The MP-20 MB irons are the least forgiving of the MP-20 family, as they are pure muscle backs with no cavity or perimeter weighting. They can handle slight mishits without losing much distance or accuracy, but they will punish you for major mishits or poor swings. You will feel every nuance of your impact on the club face, which can be rewarding or frustrating depending on your ball striking ability.
The MP-20 MB irons also have a narrow and cambered sole that is designed for better turf interaction and versatility, but it can also cause digging or fat shots if you are not careful. You will need to have a good angle of attack and a clean contact to get the most out of these irons.
Speed and Distance
The MP-20 MB irons are not designed for speed and distance, but rather for precision and control. They have standard lofts that are slightly weaker than some other modern irons, which means they will not produce as high ball speeds or distances as some other modern irons.
They also have standard lengths and swing weights that are slightly heavier than some other modern irons, which means they will not be as easy to swing fast or far as some other modern irons.
However, the MP-20 MB irons are not overly short or slow, and they still maintain a reasonable amount of spin and stopping power on the greens. They also have consistent distance gaps between each club, which makes them easy to dial in your yardages.
Feel and Sound
The MP-20 MB irons have an excellent feel and sound at impact, thanks to their forged carbon steel construction, copper underlay, and HIT technology. They have a soft and buttery feel that is not too mushy or clicky, and they produce a satisfying and crisp sound that is not too loud or harsh.
They also have a high level of feedback on where you hit the ball on the face, which helps you adjust your swing accordingly. They may not feel as fast or firm as some other modern irons, but they are very pleasing to the senses.
Playability and Workability
The MP-20 MB irons have a high level of playability and workability for players who like to shape their shots or hit different trajectories. They have a minimal amount of offset that helps you square up the club face at impact, but they can also be opened or closed to hit draws or fades as desired.
They have a thin top line and a compact head shape that allow you to see the entire blade behind the ball, which gives you more confidence and control over your shots.
They also have a standard loft that helps you hit high and soft shots that land softly on the greens, but they can also be manipulated to hit lower or higher shots as needed. They are very easy to work and allow you to hit any shot you can imagine with ease.
