The Odyssey Black Series Putter offers a rare combination of beauty- technology and performance. The putter head is precision milled from 1025 carbon steel for amazing balance- great feel and incredible accuracy. The weighted tungsten flange and hoged-out hosel allow weight to be redistributed for a low- deep center of gravity for better roll. Based on the individual head shape and its center of gravity location- the loft has been optimized to get the ball rolling sooner- meaning you get a truer roll and more accurate putts.
