Ping Redwood ZB Putter. New for 2007. Design perfection and milled performance. The new Ping Redwood Putter Series pays tribute to the home of the original Ping putter - Redwood City, California. It was in Karsten Solheim's garage that his equipment revolution was born and with it came the commitment to quality and innovation found in this 100% Ping milled putter series. Made from 303 stainless steel, the three-putter series (available in Anser, Piper and Zing shapes) offers classic model shapes designed for players seeking the very best. The black nickel chrome finish made popular in the PING Tour Wedges is the final touch. High quality 303 stainless steel is used to produce slightly heavier heads which provide a solid feel and each putter is 100% milled to create classic shapes and clean flowing lines for putting confidence.
