The new Snake Eyes Viper Tour Blade Putter carries forward traditionally shaped blade designs, with the addition of roll optimization technology in its face. Double milling lines, cut horizontally across the face, create a center friction zone. This face design requires less loft to achieve an efficient roll of the ball, and its waffle milling results in dampened vibration upon ball contact. In short, less putter material contacts the ball, resulting in a softer feel.
