These high quality Kendamas use only the best beech wood which is FSC certified, to ensure sustainable forestry practices. We have improved the handle assembly to create the strongest Ken ever made. Unlike older traditional style Kendama handles, this contemporary style does not separate during play, and simplifies the re-stringing process. The Tribute can be re-strung between right and left handed play simply and easily without taking the handle apart. The cup piece will never fall off like other brands.
