KEY TECH Use of boron increases durability of the grooves Players seeking longer-lasting spin control HOW MUCH £120 AIMED AT
One drawback we all notice with wedges is how quickly that initial zip on chip and pitch shots wears off. It’s something Mizuno wasn’t keen on either, so with its new T7 wedge (£120) it has found a way to prolong the spin you get from the grooves.
It has managed this by infusing boron within its Grain Flow Forged wedges, which it says significantly enhances groove durability.
Explaining the technology to GM, David Llewellyn, director of R&D at Mizuno, said: “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." As with the T5 wedges they replace, Quad Cut loft-specific grooves mean wider and shallower grooves from 54-62˚, then deeper and narrower grooves from 45-53˚, allowing golfers to maximise spin on all shots. The 45-48˚ lofts feature a straighter leading edge to aid full shots, graduating into a more rounded profile in the higher lofts for open-faced flop shots.
