The King Forged One Length adds additional tungsten weighting in the longer irons. For example, the 5-iron features a tungsten plug that runs through a drilled out hole low in the head and centered in the sole. The plug adds 14 grams of weight to the head that lowers the CG (compared to the standard version) and increases the club’s moment of inertia or stability on off-center hits. The space for the tungsten weight plug is unfilled on the shorter irons, which are lighter than the traditional short iron heads because of their longer shaft lengths. Again, that yields a higher CG for better control of trajectory and spin in the scoring clubs (8-iron through pitching wedge). A single-length forged sand wedge also will be available (56 and 60 degrees). Like the King F7 One, every club in the King Forged One Length is the length of a 7-iron.
