A flexible material processing rotation tool that executes processing against a target material composed of flexible material, and which is characterized by forming or more cutting blade protrusions on the surface of the substrate so that they project upward, formation of an inclined surface on the surface of cutting blade protrusion and formation of cutting blade ridge at the section that projects most upward from among the ridge areas of inclined surface, and by arrangement so that a portion of the inclined surfaces of cutting blade protrusions facing at least in one direction of the circumferential direction of the rotation of the substrate, and arrangement of at least a portion of the remaining inclined surfaces of cutting blade protrusions in at least the other direction of the circumferential direction of the rotation of the substrate.
