Claim:
1. A disposable carving blade for a carving cutter having a cutter arbor, the cutter arbor having a screw orifice positioned on an axial central line of the arbor, comprising: a blade body having a substantially parallelogramic contour and being formed with a mounting hole at a central position of the blade body, the blade body being coupled to the cutter arbor by a fastener passing through the mounting hole and into the screw orifice, an angled right cutting rim formed on a first peripheral side of the blade body, and an angled left cutting rim formed on a second peripheral side of the blade body, the angled right and left cutting rims being two adjacent sides of the substantially parallelogramic contoured blade body; wherein the right cutting rim is configured with the left cutting rim to form a substantially V-shaped portion, the substantially V-shaped portion terminating at a cutting edge defined on a distal end thereof traversing the axial central line of the cutter arbor to extend transversely between the right and left cutting rims, and an intersection point reference cooperatively defined by predetermined angular convergence of a reference line projecting from the right cutting rim on the first peripheral side of the disposable carving blade and another reference line projecting from the left cutting rim on the second peripheral side of the blade body, the intersection point reference further defining a point of intersection with a central line of the blade, the central line of the blade being offset from the axial central line of the cutter arbor at the intersection point reference to be non-coincident therewith, and a distance between the intersection point reference and the axial central line of the cutter arbor defining a first eccentric value with respect to the axis central line of the cutter arbor, wherein a length of the right cutting rim is asymmetrical to that of the left cutting rim.
