Was designed sole ingenious "diamond cut" is the soft iron forging wedge of features. The "diamond-cut", only after utilizing the bounce, by discharging moderately sand or grass, is designed to prevent excessive splashing of the sole. In order to leave so that it can be used to bounce to the left, can be discharged of sand and turf only the central portion, heel portion will be minimal resistance. As a result, in addition to the operability and tenderness, it became wedge equipped with the goodness of missing pleasant. The score line by CNC machining and sole shape that has been calculated. Spin performance is high, the height of the operability to his bite firmly on the face is also attractive.
