Yuta Takeuchi of Fourteen Golf introduces three major elements of wedge backspin that are critical in understanding why Fourteen’s wedges are cutting edge.
The three elements of flight (initial velocity, high launch, low spin) are famous, but do you know the three major elements that determine the backspin of a wedge? It's not as popular in the golf media, but I'll explain the physical mechanisms unique to "Wedge Fourteen".
#1 Face friction
With the face, the ball and the frictional force, you should be able to easily imagine the mechanism of spin. What is important is the flatness accuracy of the face surface. It may seem like a natural answer, but flattening the face requires a great deal of manufacturing technology. The reason why FOURTEEN wedges have a reputation for "spinning" is that they have been more particular about flatness accuracy than the "MT-28" that laid the foundation for it.
#2 Score line
It is the role of the score line that is caught in the soft urethane material to exert the spin power of the urethane cover ball called the tour system. Do you remember that FOURTEEN released a highly accurate square groove with "MT-28" and dominated the world with its overwhelming spin power? After that, many late models came out, but in 2010, the square groove was regulated. However, after that, FOURTEEN continued to stick to the structure and accuracy of the groove and secured spin performance comparable to that of a square groove. "Wedge Fourteen" is still alive.
#3 Rotating elements brought about by contact with the ball
Professional golfers' wedge shots show a strong backspin that resembles a return on the green, most notably due to good contact below the center of the ball. The FOURTEEN wedge has realized such professional golfer's technology naturally with ease of handling by the shape of the unique wedge.
Taking full advantage of this technology, the new RM-4 Wedge is available throughout North America at FourteenGolf.us
