The Mizuno MX-1000 irons from Mizuno features the companies Hot Metal technology, originally designed for their wood and hybrid ranges but now extended into iron design with the arrival of the MX-1000.
Mizuno say the Mizuno MX-1000 is the ultimate club for those golfers looking for the perfect combination of both extra distance and extreme forgiveness. The revolutionary design delivers distances that push the boundaries of R&A and USGA performance limitations by the adoption of plasma welding a thin, hot, ES230 maraging steel face with a 431 stainless steel body, a process first used in Mizuno’s MP Fli-Hi utility iron.
I'll be honest with you, I feel like I really need to throw everything I believed about irons in the "game improvement" category out the window. Quickly. The Mizuno MX-300 irons changed my mind about what a game improvement iron should be and how a game improvement iron should feel. And this is coming from someone who thinks the constant Mizuno praise gets a little old sometimes.
Though labeled as a game improvement iron, the Mizuno MX-300 exudes the beauty that you might normally find in a blade. The thin top line is an indication that these irons don't exactly fit squarely into that GI category, and thus are not very bulky or excessively thick. Looking at the cavity, the Y-Tune Pro is immediately identifiable by the "Y" shaped relief, as well as the "Y-Tune Pro" badging on the top hosel side of the cavity.
So although the MX-300 could be in danger of having an identity crisis, Mizuno is confident that they fill a niche that lies between the shadowy boundaries of low and mid handicaps.
