Embodiments according to the present invention provide improved rotary cutters and associated methods. A cutter includes a handle coupled to a plurality of rotary cutting elements which may be rotatable substantially within the same plane, within closely spaced parallel planes, or within intersecting planes, wherein the intersection of such planes occurs substantially tangential to the rotary cutting elements. The rotary cutting elements are preferably different sized and preferably becoming smaller distally from the handle. A method includes cutting an article with a plurality of rotary blades with a single motion of a human hand and/or arm. Such article may be, for example, a food article, such as pizza, or a textile article, such as leather, vinyl, or even gypsum board.
