A plurality of blade portions are arranged on the blade body, and the blade portion is specifically five. A plurality of grooves are arranged on the blade portion, and the cross section of the groove is triangular. When the blade is working, not only can the shear force generated by the tip of the blade be used to shred the object, but corresponding shear forces can also be generated between the grooves. Since there are several grooves, after the object is sheared by the tip of the blade, the object is sheared for the second time by the grooves, so that the object is effectively decomposed into smaller pieces. Since no additional structure is required, the overall weight of the shredder will not be affected, the required cost is small, and the application range is wide.
