Inner Cavity DesignThe IC-601 irons feature Miura’s proven inner cavity design, first introduced in the popular IC-2003 model. This design redistributes weight within the clubhead to enhance forgiveness and promote a higher, more consistent ball flight. The wider sole further supports this by improving turf interaction and ensuring stability through impact.Carpenter Steel Face & Weighting SystemA face constructed from 455 Carpenter Steel enhances ball speed while maintaining Miura’s renowned feel and precision. Each iron includes an 8g back-weight screw, aligning with modern equipment standards to allow seamless custom fitting. This variable weighting system enables golfers to match their preferred shaft options without compromising performance.Enhanced Forgiveness & ConfidenceThe IC-601 irons are designed to inspire confidence at address. The combination of a larger sweet spot and stable sole design ensures improved forgiveness across the set, from the 4-iron to the pitching wedge. Whether you're aiming for longer carries or improved accuracy, these irons provide a consistent and controlled ball flight.Specifications Head Loft Lie FP (Face Progression) Weight Length 4i 22 ° 60 ° 1.0 249g 38.50" 5i 25 ° 60.5 ° 1.0 256g 38.00" 6i 28 ° 61 ° 1.1 263g 37.50" 7i 31 ° 61.5 ° 1.1 270g 37.00" 8i 35 ° 62 ° 1.2 278g 36.50" 9i 40 ° 62.5 ° 1.2 285g 36.00" PW 45 ° 63 ° 1.2 293g 35.75"
