Ping Blueprint S Golf IronsDeveloped following extensive testing with our top tour pros to meet their “must haves” -- control and precision -- Blueprint S delivers the score-lowering performance demanded by the best players in the world.The compact shape fits the discerning eye with a thin top line and minimal offset. The 8620 carbon steel head boasts a clean cavity design, distinguished by an eye-catching forged textured pattern and hydropearl 2.0 chrome finish. What further sets this iron family apart is the split-set construction technology called “precision pocket forging.” This patented forging technique allows us to forge a pocket into the cavity of the 3, 4 and 5 irons. The pocket saves 10 grams of weight, which is re-allocated to increase the MOI and optimize the center of gravity position for more distance and trajectory control. An elastomer insert is concealed in the pocket of the 3-5 irons, ensuring the solid feel and sound expected in a forged players iron. The 6-iron through pitching wedge are sized and shaped to ensure workability and control.
