Pursuing the best hitting feeling in the series. Limited Blue Edition model with limited quantity. Grain Flow Forged HD 1025E. Mizuno’s unique forging process, in which a single round bar is integrally molded from the face to the neck. The forged flow lines (flow of metallic tissue), which can be said to be the lifeline of the hitting feel, are not interrupted inside the head, and by concentrating the forged flow lines in the hitting area, the hitting sound can resonate for a longer period of time. This long, resonant hitting sound allows the player to experience the comfortable hitting feel that only Mizuno can provide. Reverse Tapered Blade Design. The blade section is thickened toward the top edge in pursuit of a solid hitting feel. By grinding the back of the top edge, a sharp face and solid feel are achieved. Furthermore, the thickness of the blade section is varied for each club to optimize the sweet spot height for each club. Long and middle irons have a high trajectory, while short irons have a low launch and high spin to hit the green. Based on the Muscle Back irons, which have been called “masterpieces, ” the entire head has been designed to be compact. The maneuverability of the short irons has been further improved. Fusion of Technology and Craftsmanship. We have combined cutting-edge technology with the finely honed skills of our craftsmen. We pursued the best feeling and performance. Copper plating is used. Although the difference is slight, the feel is softer and the contact time of the ball on the face is longer than usual. There are individual differences, so it is not possible to make a general statement. Mizuno’s special hitting feel is designed with the latest technology. The height, loudness, and tone of the sound, which affect the feel, are tuned in units of tens of hertz. Mizuno’s unique design method produces a comfortable hitting feel that is unique to Mizuno. Mizuno’s commitment to soft-iron forged irons. GRAIN FLOW FORGED manufacturing method (Forged streamline forging) World patent acquired. The “GRAIN FLOW FORGED” manufacturing method is Mizuno’s unique manufacturing method patented around the world that does not break the forged flow line from the head to the neck. The “GRAIN FLOW FORGED” manufacturing method is Mizuno’s unique manufacturing method patented worldwide that does not break the forging line from the head to the neck, and creates Mizuno’s “hitting feel”. Soft iron is officially low carbon steel, and materials such as S25C (0.25% carbon content) are generally used in soft iron forged irons. However, the soft iron used by Mizuno differs from these materials in that Mizuno uses “S25CM (1025E), ” a carefully selected material with few impurities and a fine metallic structure. This “S25CM” creates Mizuno’s “feel”. Shafts Dynamic Gold Tour Issue Limited Edition for Mizuno. Set Contents 7-piece set (#4-#9, PW). Head Material Mild Steel (S25CM), 1025E.
