Abstract

A cutter includes a cutter handle and cutter head including a main body and a plurality of curved cutting edges separately extending from a periphery of the main body. Each cutting edge has a top surface, a first side blade surface, a second side blade surface, and a bottom surface. The top surface, the first side blade surface, the second side blade surface, and the bottom surface intersect to form a front edge, a middle edge, and a back edge. The front edge, the middle edge, and the back edge cooperatively form an edge tip. A tangent of the middle edge at the edge tip intersects with the bottom surface to form a cutting angle in a range from 30° to 60°.
