Golf is difficult because using a golf club well depends on the < distance from center of gravity>
The < distance from center of gravity> is the distance between the center of gravity (= sweet spot) on the face and the centerline of the shaft.
This is one of the major factors that makes it difficult to use a golf club well.
Even though they involve hitting a moving ball, simply hitting the ball is not so hard in table tennis and tennis.
That's because the sweet spot lies on the extended line of the grip (= shaft).
This is the definitive difference between golf and other sports.
Depending on the distance from the center of gravity, a golf club that does not have a sweet spot on the
extension of the shaft will create misalignment due to the natural human instinct to hit on the shaft
Conversely, if the distance from the center of gravity is short, it less likely to cause misalignment due to that natural human instinct.
In golf club rules, the only club that is allowed to have a sweet spot on the shaft axis is the
Like table tennis and tennis rackets, < AXEL ZERO DISTANCE PLUS DEEP-G putter> which has a face with zero distance from the center of gravity, offers the greatest advantage for intuitive ball hitting on the kick point of the face = the sweet spot.
Do not open or close the face, pull straight and hit straight.
This alone allows the golfer to putt in the way they envision.
Since there is no distance from the center of gravity,
you can intuitively hit the sweet spot.
On the other hand, with an average putter with distance from the center of gravity,
it's difficult to intuitively hit the ball’s sweet spot.
The toe-heel weight, which is commonly installed on average putters, is cut to increase the cavity area.
The resulting excess weight is allocated to the toe-heel of the back face.
The center of gravity has been deepened and the moment of inertia has been greatly improved.
With a deeper center of gravity, the deep center of gravity pushes the ball naturally while minimizing head shake after the face makes contact with the ball.
Computer-controlled CNC cut machining is used to precisely design the head.Depending on the viewing angle,
The face section, in particular, has been cut stepwise on the surface to minimize the contact area with the ball, resulting in overwhelming softness of the impact.
