Mizuno T7 wedges

Luke Donald first gave us a hint something exciting was in the works from Mizuno last month and now the new Mizuno T7 wedges have been officially revealed.

The Englishman replaced his 54˚ and 60˚ S5 wedges with Mizuno T7 designs of the same loft ahead of this year’s Open Championship. Today, Mizuno has officially revealed T7 as its first Grain Flow Forged wedges infused with Boron.

Boron-infused metal has been a feature in the brand’s iron releases in recent years. It has now made its way into the Mizuno T7 wedges with the brand saying the extra strength it gives the metal makes the grooves stay sharper for longer.

Similar in shape to the MP-T5 wedges they are replacing, the Mizuno T7 wedges are a more compact design than the S5 wedges. The feel they can offer comes from the Grain Flow Forging, while the control and spin comes from the improved loft-specific Quad Cut grooves.

Wider and shallower in the higher lofts (54˚ to 62˚), then deeper and narrower in the lower lofts (45˚ to 53˚), Mizuno has used a more precise milling tool to ensure the grooves are cut as tight as possible to the limits set by the governing bodies to give the most possible spin on both full and partial shots.

As well as the grooves, the Mizuno has varied other aspects to ensure the T7 wedges can fit seamlessly into your set with proper distance gapping.

The pitching wedge lofts from 45˚ to 48˚ feature a straighter leading edge and topline for fuller shots, before offering a more rounded profile in the highest lofts from 58˚ to 62˚. The grinds are also more visible in the higher lofts as Mizuno wanted to narrow the sole to give ‘crisp ball-striking’ from a wide variety of lies.

“The one drawback with a traditional soft forged wedge is that the grooves compress more quickly than a harder cast wedge,” says David Llewellyn, director of R&D at Mizuno.

“A very small trace of Boron in the steel means we can not only now maintain that forged feel and precision, but also the performance of the grooves and the wedge’s stopping power over a longer period of time.

“Our only concern using Boron was whether the feel would be compromised. Luke Donald was the best tester for that issue and he asked to put them in his bag after one session.”
