[From the Manufacturer's Introduction] A traditional half-cavity iron that has evolved the feel. The head uses Mizuno's unique forging process, "Grain Flow Forged HD," which allows for the one-piece molding of the face and neck, achieving a long-lasting impact sound that affects the feel. In addition, "copper underlay plating" with low-hardness copper is used for the underplating of the head's plating to achieve a softer feel. The sole features a rounded three-point design, employing a Luke sole that prevents excessive digging into the turf and provides good turf interaction. Long irons have a longer head length for a sense of security. As you move to the short irons, the head length is shortened to improve operability and head release. For golfers with a slightly level-blow swing who want to control the head's rotation with a longer center of gravity distance than the Mizuno Pro 118.
