By bonding ultrafine diamond with advanced ceramics, this stone offers a high degree of bonding in addition to a long life span.
It is the only grindstone of this size in the world to be commercialized with the advanced ceramics bond type (according to our company’s research).

  • （1）It features a smooth sharpness as the blade will be unlikely to scratch.
