Abstract: A cutting apparatus includes a first cutting member and a second cutting member. The first cutting member includes a first handle and a first cutting blade. The first cutting blade includes a first blade support, and a plurality of blade members spacedly and inwardly extended from the first blade support. Each of the blade members has an elongated first blade portion and a tip portion extended from the elongated first blade portion. Each of the tip portions has a first cutting edge, at least a first guiding surface, a second guiding surface and a guiding edge formed as a boundary between the first guiding to surface and the second guiding surface. A vertical height of the first guiding surface and the second guiding surface gradually decreases from the guiding edge. The second cutting member includes a second handle and a second cutting blade.
