Use of special boron material provides longer lasting groove definition in the new Mizuno T7 wedges for added control and durability
The lid came off the new Mizuno T7 wedges at this year’s Open Championship when staff player Luke Donald added a set to his golf bag, replacing his Mizuno T5 wedges. The T7s are Mizuno’s first Grain Flow Forged wedges infused with Boron and feature precision-milled Quad Cut grooves for longer-lasting spin control.
The new T7 forged wedges deliver Mizuno’s distinctive soft Grain Flow Forged feel but with significantly enhanced groove durability thanks to a small infusion of Boron within its steel.
“The one drawback with a traditional soft forged wedge is that the grooves compress more quickly than a harder cast wedge,” David Llewellyn, Director of R&D at Mizuno, told GM.
“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 with 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.”
The spin control performance of the face has already been enhanced by a new, more precise milling tool that allows the loft-specific Quad Cut grooves to be cut as tight as possible to R&A and USGA limits for even more spin. Those loft-specific grooves are wider and shallower in the higher lofts from 54˚ to 62˚, then deeper and narrower in the lower lofts from 45˚ to 53˚, allowing golfers to maximise spin on both full and partial shots.
The grooves aren’t the only things that vary according to loft, with the pitching wedge lofts from 45˚ to 48˚ featuring a straighter leading edge and topline for fuller shots, graduating into a more rounded profile in the highest lofts from 58˚ to 62˚. Those higher lofts also boast more visible grinds that narrow the sole to deliver crisp ball-striking from a wide variety of lies.
Mizuno has been Grain Flow Forging its iron and wedge heads since 1968, a process that compresses and maintains a consistent grain through the neck and hosel delivering the feel and the precise distance control so crucial in the wedge game. T7 wedges are available in the standard White Satin finish, or the unique Blue IP finish that debuted in last year’s S5 wedges.
The new Mizuno T7 wedges are available in lofts 45° to 62° with and RRP of £120 per wedge.
