Cutting blade and system that allows all the freedoms of the three-side-ground cutting blade while using a two-side-ground cutting blade. A new cutting edge can be defined on the two-side-ground cutting blade that will duplicate the tooth surface cut by the three-side-ground cutting blade with different hook and side rake angles. The new cutting edge of the two-side-ground cutting blade is determined by a plurality of points, each point corresponding to a point on the three-side-ground cutting blade, such that when cutting, each point along the cutting edge of a two-side ground cutting blade will lie on the same epicycloid generated by the corresponding points on a three-side-ground cutting blade with different hook and side rake angles.
