Hot List Gold 2023

Our Review:

WHAT IT DOES: You might think that a metal used for the landing gear of fighter jets would be strong enough for a golf club. That’s the chromoly 4140M metal Mizuno used in previous versions. Apparently, the company found itself bumping up against some strength limitations, so it needed to find a new material. Enter nickel chromoly 4335—an extremely powerful material that’s used in other industries for critical parts. The new alloy allows for the thinnest face ever on a Mizuno iron at 1.75 millimeters, or basically the thickness of a quarter. 

WHY WE LIKE IT: This iron features a relatively compact shape and thin topline to fit the eye of better players seeking workability as much as distance. The single-piece construction creates the kind of ball speed one usually associates with a special face insert and does it consistently across the face because it doesn’t require weld beads to join the parts. Speaking of lofts, because so much weight is placed low and back, the lofts can be aggressive without sacrificing height. The 7-iron loft is 28.5 degrees, or basically the same loft as a Mizuno game-improvement 6-iron from a decade ago.  Read more>>

"This is a golf club for the ascending player. There's a lot of room for growth while using this club. Real professional feeling through the impact zone. Perfect weight. Comfortable swinging experience. And on top of that, it's good looking."

"A very comfortable look at address. Lives up to the name Hot Metal. Really jumps off the face. Wasn't sacrificing anything. Mis-hits were controllable. As reliable as your best friend."
Handicap, 14
"So clean and efficient through impact. The clubhead really framed the ball nicely. These felt like an extension of your hand. Really like the trajectory. Great click whoosh off the face. You feel like you can really attack the green."
Handicap, 15
“Super easy to hit. The ball takes off with a high launch, and the sound is confidence-inspiring. It can mask the miss, too.”
