HAMMOND was developed by Nittaku under the brand-new idea “Integrated Energy (IE)”. This technology applies a newly developed way of making natural-rubber and synthetic-rubber. The results of the latest Japanese production methods are: (1) The natural-rubber ingredient grabs the ball firmly, (2) At the next moment, the synthetic-rubber ingredient shoots the ball like a bullet. In addition, pairing the hard type top-sheet with the soft type sponge, both made in Japan, will bring the best results and performance with the 40mm-ball.
