KEY TECH Use of boron in­creases dura­bil­ity of the grooves Play­ers seek­ing longer-last­ing spin con­trol HOW MUCH £120 AIMED AT

Golf Monthly - - Rory Mcilroy -

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.
