Other alternative was to reinforce the spike with a glue to prevent crushing. However, if a spike reinforced with a glue etc. is too rigid, the excessively rigid spike hitting the tama causes bumps on the tama surface. The “spike replacement technology” is a technology developed to prevent such spike and tama damage. By using a replaceable resin material for the spike, Kendama can last three times longer than before. Since the resin material used “damages the tama if too rigid, but bounces off the tama if too soft”, we have conducted a multitude of tests and developed a resin material with an original mixture of ABS and PP. We achieved the ideal rigidity for Kendama. Kendama spike replacement technology is MUGEN MUSOU’s original technology and we are currently waiting for its international patent to be approved.
