The subtly tapered top has allowed the centre of gravity to be placed higher up on the wedge which helps you put more spin on the ball. The club head is made from boron-enhanced steel which is more durable than regular steel, making the grooves hold better and putting spin on the ball for longer. The grooves are precision milled for consistent results and differ from the lower and higher lofted wedges to give optimum spin on every shot. Mizuno’s new Hydroflow Micro Grooves technology means that there are also small vertical millings on the club face which help to direct moisture away for more consistent spin even in wet conditions.
