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 endeavour. However, Mizuno achieves it by using a special kind of steel called chromoly 4140M, a material that has been used in high-tech bicycle frames. With a high strength-to-weight ratio, the steel allows Mizuno to make a face as thin as 1.9 millimetres in certain areas, resulting in more flexibility that produces surprising distance. Three additional ribs added to a structure inside the topline further stabilise the frame and optimise 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 on 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.”
