MUQU is made to match the player which is a whole new concept. It is common to change the position of the ball and the swing depending on the number of the iron, but in recent years it has become mainstream to hit the ball with the same swing regardless of the number. For each specific player, MUQU closely controlled all numerical values at the design stage, and maintain the height of the center of gravity made the center of gravity distance constantly. This makes it possible to fly the ball according to the angle of the count while keeping the position as designed. And thanks to the technology of the 5-axis CNC which machine-cuts the head which does not differ from the design.

MUQU is designed by 3D CAD, and is cut out by 5-axis machining that can give an accuracy of 0.01 mm. A manufacturing method different from forged or lost wax process. The Manufacturer MS Seisakusho Co., Ltd., has been highly evaluated in the automotive industry for its technology for manufacturing molds. Produced golf irons with the ability to calculate even the subtle distortion of iron due to processing. Conventional clubs always require manual processing. Therefore, it would be impossible to make identical golf clubs. However, MUQU is made by machining center only, so if you make ten, you will get ten identical iron heads.

The back face is finished in a pure and beautiful simple design. A new idea was also included in this simplicity. "We expressed muscle back in the cavity," says the designer. The shape of the undercut that can be achieved with 5-axis machining. By cutting diagonally, I left a thick part and made the hit feel firm. A new design that can be called just functional beauty.
