Mitsubishi MMT Iron Shaft Review: A Graphite Gateway
The notion that graphite iron shafts cannot endure aggressive swing speeds or provide tour-level control is quickly fading. Mitsubishi addresses this doubt directly with the MMT series, incorporating a specialized metal mesh into the tip section to combine plush vibration damping with steel-like stability.
We subjected the shaft to our standardized launch-monitor testing to determine if its flight consistency and feel match the expectations.
How We Test Shafts

All our shaft testing utilizes the same TaylorMade Qi35 core head driver set to a precise 9 degrees (measured), with each shaft cut to an exact length of 45.5 inches and fitted with a Golf Pride Tour Velvet 60R grip. Additionally, all testing shots are struck from a white castle tee to maintain consistent tee height throughout the evaluation.

Data collection and recording are performed using a Foresight Sports GC3 launch monitor alongside TaylorMade TP5x golf balls.
Managing these potential variables enables me to draw accurate and direct comparisons, forming a clear understanding of each shaft’s performance and feel characteristics.
Mitsubishi MMT Iron Shaft Review: Technology
The MMT (Metal Mesh Technology) stands out through its unique composite construction. Mitsubishi embeds a specialized metal mesh in the shaft’s tip section to greatly enhance stability and consistently generate center-face strikes required for elite iron play.

The shafts come in both taper-tip (with a premium gloss finish) and parallel-tip (with a matte finish) options. The fitting range is impressively broad, with weight and flex options scaling from a lightweight 55g A-flex up to a robust 125g TX-flex.
Mitsubishi MMT Iron Shaft Review: Performance
For my testing, I employed the 105 TX model. Although this is significantly lighter than my usual Dynamic Gold X100 shaft (which weighs approximately 130 grams), the MMT delivered remarkable stability and flight consistency.
I must admit that I initially struggled to achieve the strike consistency I desired, but this was solely due to the substantial weight change from what I was accustomed to. Adding around 12 grams of lead tape to the grip base completely transformed my strike consistency, leading me to believe the 125-gram version could be absolutely ideal for me. Based on how much I enjoyed the feel and performance, Mitsubishi, I may be reaching back out!

Among all graphite iron shafts I have tested to date, I would say the MMT feels the smoothest to me. However, do not confuse smooth with soft; they offer more than enough stability for me, and I swing at or slightly above PGA Tour average speed. While one or two other graphite iron models I have tried have popped the ball flight up slightly, that is not the case here.
Controlled, penetrating flights were the standard for me, which is something I always seek.
I have long been a proponent of the feel and vibration absorption properties of graphite in irons, and nowhere has this been confirmed more than with the MMT model. Off-center strike vibrations are significantly subdued, diffusing the harshness often associated with mishits. Think of it somewhat like the silicone vibration dampener found on a tennis racquet.

The consistency of launch and spin numbers once I found an appropriate weight was very reassuring, and a total non-negotiable for me.
Finally, I greatly appreciated the minimal graphics and branding Mitsubishi has used on the MMT. The minimalist, monochrome design will pair well with any head and shaft combination.
Mitsubishi MMT Iron Shaft Review: Verdict
If you are looking to make a first foray into the world of graphite iron shafts, the Mitsubishi MMT feels like an excellent place to start due to the compelling combination of feel and stability.
