Is not evolution. A newborn.
■ “progressive weighting system head”
Katana new ideas and technology, has rallied here by the weight distribution and the sole is molded to like “groove” of its own.
In addition to the repulsive force of the entire head moment of impact, the weight of the weights are synchronized propulsion,
The gradual loss of power without amplification while progressive wave effect (progressive), (※ 1)
Maximum hammer effect, I flicked the ball.
Deep set low, the position of the center of gravity with great care, even though the moment of inertia is up,
This head, I was able to more than ever, to reduce the amount of spin by the progressive effect.
Can proceed step-by-step = (forward) progressive (※ 1). Represents an image that is a step-by-step advance weights section which is formed in the sole portion.
■ Face & Crown Technology
VOLTIO driver, there are four circles in the center of the face.
I have something to do with the spec test time and again by changing the position of the circle, the thickness, the widest SS figures came out.
Effective dot area spread This has become tolerant to head misses.
In addition, the crown of the head, lighter up to the limit of very thin to withstand the shock of impact,
I have formed “skip entire bend” the head structure.
By this face and crown is the combination that I pull out the maximum rebound performance was made possible
