Legendary club maker Clay Long designed the Tour Preferred EF wedge ($160) with electroformed nickel cobalt grooves. These groves are more durable and, most importantly, they provide the correct amount of spin for a longer duration. We like the glare-reducing dark smoke PVD finish and the soft 1025 carbon steel body. These provide excellent balance and distance control with a choice of lofts from 47 to 62 degrees. The face insert is only .25 mm thick and is created with the ionization of nickel and cobalt in an electrolytic solution. The solution is then deposited onto a master plate containing the design of the grooved and micro-textured surface.
