Major brands have used “variable thickness technology” for decades. This technology has the thickest part of the face in the center, where the highest trampoline effect exists to ensure that the face does not have a CT higher than 257. Then the thickest part of center is thinned to outer edges of the face in an effort to compensate for the reduced trampoline effect. However, despite this thinning the CT values in the large toe and heel areas are much lower which is a reason amateur golfers lose so much distance on toe and heel hits.

Knuth Golf invented the novel idea of creating three, largely independent trampolines in the face, which could create a much higher CT with a thinner face in the toe and heel areas. We did so by significantly and immediately reducing the average thickness of the Impact Area adjacent to the toe and heel areas to obtain the “hottest face in golf.”
