The Adams Idea Pro Black CB1 irons have a forged 8620 carbon steel construction that provides exceptional feel, performance and feedback for the skilled player. The head has a cavity that is milled to provide a Center of Gravity that results in a piercing ball flight as well as milled grooves that maximize spin from all playing conditions. A thin top line, beveled trailing edge, nickel-Chromium plating and constant offset throughout the set delivers performance and control along with a sleek design.
