1. A cutting blade comprising a section of a domed external surface and a section of a domed internal surface being concentric about a rotational axis to the section of the domed external surface thereby defining a section of a hollow dome, wherein at least one cutting tooth comprising a cutting edge, a crest and a cutting surface is disposed on the section of the hollow dome and wherein by virtue of the cutting surface having been formed by an injection molding process or a 3D printing process, a cross-sectional thickness T measured substantially perpendicular to the crest of the at least one tooth is greater than a radial distance t between the section of the external and internal domed surfaces, wherein further the section of the external and internal domed surfaces of the section of the hollow dome are interrupted by at least one portion of a hole passing therethrough defining the cutting edge and the cutting surface of the at least one cutting tooth, the cutting edge comprises the crest, wherein the at least one portion of the hole passing therethrough is cylindrical.
