Mizuno’s new T7 Wedges are Japanese-Forged with Boron



Mizuno has been strategically adding a material called boron to several of its new forged irons in recent years, the benefits of which have been longer-flying, more forgiving irons that retain the company’s signature feel. With its new T7 wedges, Mizuno is claiming that boron isn’t just the answer for better forged irons; it can also make better forged wedges.


Instead of adding distance and forgiveness to the company’s new T7 wedges, trace amounts of boron were used to create a forged wedge with more durable grooves.

“The one drawback with a traditional soft, forged wedge is that the
grooves compress more quickly than a harder, cast wedge,” says David Llewellyn, Mizuno’s Director of R&D. “A very small trace of boron in the steel means we can now maintain the forged feel and precision, but maintain the performance of the grooves and the wedge’s stopping power for a longer period of time.”


The T7’s grooves have also been improved with a new milling tool, according to Mizuno, which allows their Quad-Cut grooves to be machined closer to the USGA/R&A limits. The result is more consistent grooves with tighter tolerances, which creates more spin around the greens.

The configuration of the new grooves also varies based on loft; they’re narrower and deeper in the lower lofts (44-53 degrees) for better performance on square-face shots, and wider and shallower in higher lofts (54-62 degrees) for better performance on open-face shots.


The T7 wedges ($149 each) are forged in Mizuno’s Hiroshima (Japan) plant, and use the company’s “teardrop” club-head shape. They’re available in lofts from 44 to 62 degrees in 1-degree increments, and are offered in two finishes: Blue IP, which wears to a chrome finish, and white satin.

The stock shaft is True Temper’s Dynamic Gold Wedge Flex. The stock shaft is Golf Pride’s MCC Blue/Black 60 Round. Custom stampings of 6 characters and 12 colors can also be added.

They’ll be in stores on Sept. 16.

      Exactly. So everything that Llwellyn says about how a forged wedge compresses the grooves so they added Boron – makes no sense at all. Don’t these manufacturers understand that people can surf the web and find info?

    Was at their flagship store in Osaka today. Other than hitting the 5s, the 55s, the fli-his and seeing all the new woods, hybrids, bags, clothes and shoes… I was gonna make a joke. I’m totally horny for some Mizuno.
