Mizuno Golf brought boron into its forging process in its JPX line of irons, and the improved strength of its steel alloy has been a hit. Now the company has brought that same boron-infused steel to the forging process of its new T7 wedges.
Luke Donald put the T7 wedges into play at the Open Championship, and they drew a lot of attention.
The T7 wedges use the 1025 Boron-infused steel and are forged with the company's Grain Flow process. Using this material in the forging process allows Mizuno to make a wedge with quad-cut grooves that have improved durability.

The initial concern among Mizuno's design team was that the material switch might compromise feel. However, that's not the feedback the company got from Donald or its other staffers.
The groove cuts on the T7 wedges are specific to loft, as well, with wider and shallower grooves from the 54-62 degree wedges, while deeper and narrower on the 45-53 degree wedges for more spin and control on the longer swings used with those clubs.
The topline varies through the line based on loft, too. The 45-48 degree pitching wedges have the straightest leading edge and topline for a consistent look for full shots. The rounding on both increases through to the high-lofted wedges. The sole narrows, too, as loft increases to offer more grinds with more options for executing from any lie a player will encounter.
Like with the S5 wedges, the T7 wedges are available in White Satin or Blue IP finishes.
The Mizuno T7 wedges will be available in September in 26 different loft-bounce combinations.
