A disposable carving blade (10) contains a central hole (11) defined at a central position thereof, a first central line (15) passing through the central position thereof, a right cutting rim (12) formed on a first peripheral side thereof and a left cutting rim (13) formed on a second peripheral side thereof. The right cutting rim (12) is connected with the left cutting rim (13) to form a V-shaped portion, and the V-shaped portion includes a cutting edge (14) defined on a distal end thereof. An intersection point of the right cutting rim (12) on the first peripheral side of the disposable carving blade and the left cutting rim (13) on the second peripheral side of the disposable carving blade (10) is adjacent to the first central line (15), and a distance between the intersection point and the first central line (15) is a first eccentric value (e). |
