The Titleist Forged 735.CM irons are a progressive cavity/muscleback set that provides extra forgiveness in the long irons with control in the short irons. Forged from 1025 mild carbon steel for soft feel, these blades have progressive shaping, weighting and offset to enhance the characteristics most needed from each individual iron in the set. The long irons are cavity backed to give players maximum forgiveness in a forged iron with low Center of Gravity and high Moment of Inertia. The mid irons have a shallow cavity that allows CG to be higher for enhanced control and the short irons are pure musclebacks to give skilled players the ability to control ball flight to stick approach shots close.スペックIronOffsetBounceLoftLengthLieSwing Weight3 Iron.140"1°22°39.00"60°D2
