Deflection by the high tilt (groove) with high ripple johnsor and integral structure of the body and face expand the repulsion area of the wide hyper effect face to the limit. By pursuing both the deflection and the restoring force of both the face and the sole to the limit, it pushes the ball strongly and achieves further flight distance increase. In addition, by enlarging the face high initial velocity area more than the previous work, we realized a gentle iron that further reduces the distance loss due to off center hits.
By making the tungsten weights throughout the sole, we realized deep · low center of gravity by optimizing the female golfer ‘s swing, so that the ball is easy to go up and the miss hit makes the distance loss less. A high, strong trajectory brings up a flying distance to female golfers.
