JPX921 Hot Metal
Creating a hot face in an iron without resorting to the cupface and L-face designs found in a lot of the clubs on our list is a difficult endeavor. However, Mizuno achieves it by using a special kind of steel called chromoly 4140M, a material that has been used in hightech bicycle frames. With a high strength-to-weight ratio, the steel allows Mizuno to make a face as thin as 1.9 millimeters in certain areas, resulting in more flexibility that produces surprising distance. Three additional ribs added to a structure inside the topline further stabilize the frame and optimize feel. You might need a doctorate degree in acoustics to understand the sophisticated work Mizuno has done in the area of sound throughout the years, and the company has done it again here, delivering a pleasant tone at impact—not an easy accomplishment in a face this thin. Having learned that a substantial portion of its iron orders are for mixed sets, Mizuno fine-tuned the specifications of the entire Hot Metal family to better align the irons and their lofts, making for a seamless transition for those who might want to pair the Hot Metal long and middle irons with the Hot Metal Pro short irons.

I discovered a smooth swing with this iron. The distance is good, and the ability to shape shots is there. Pretty consistent distance.
Great looking club and it performed well. Ball jumped off the face with low side spin
Incredibly forgiving. A nice ball flight and sounds compressed even if you don’t hit it pure.
