EV12 Putter Compact mallet with oversized performance Precision milled, extruded 6061 aluminum body 303 stainless steel wings surround the body in the rear corners Three times heavier than previous series, the steel wings amplify stability and forgiveness SweetFace(TM) Technology EVEN ROLL DISTANCE Because the channels get narrower away from the center, the spacing gets wider. This increase in contact surface means more energy transfer and replaces the energy lost when a ball is hit away from the sweet spot. So center and off-center hits travel the same distance. ZERO DISPERSION A series of closely spaced variable width channels that are wider in the center and get gradually narrower toward the heel and toe. This creates a precisely calibrated inward v-shape from both the heel and toe that progressively redirects the ball down the target line.
