Mizuno's Grain Flow Forged heads combine the softest feel with spin control only possible through the use of loft specific Quad Cut Grooves. Mizuno's Quad Cut Groove concept utilizes a wider, shallower groove from 54-62 lofts (to grab softer, partial strikes) and a narrower, deeper configuration from 49-53 degrees (for fuller shots). When it comes to wedge performance, the MP-T5 is the total package.
