Abstract: A cutter for cutting continuous stock materials into discrete lengths is disclosed. The cutting device includes a plurality of rotatable cutting tools or blades extending transversely across a cutting zone. The cutting tools are mounted in a common plane, are intermeshed, and are synchronously driven in opposite directions. The cutting zones of the intermeshed cutting tools overlap and thus the cutting device is capable of performing the cutting operation by movement in one direction through the material being cut. The cutting tools have opposed segments that carry cutting edges. In one form of tool, the cutting edges are spaced from the axis of rotation of the cutting tool by a distance that continuously increases in a direction opposite the direction of rotation of the cutting tool. This change in distance can be related to the speed of rotation of the cutting tools and the speed at which the cutting tools are advanced through the material being cut.

Abstract: An elongated hollow miter box embodying spaced-apart top and bottom walls has its ends bevelled on a 45.degree. bias. A pair of fixed guide edges on the top wall of the box are parallel to the bevelled ends and serve to guide the usual slide shoe of a portable electric saw over the top wall to effect a 45.degree. cut through either end of a wooden molding or other strip which is positioned and held on the bottom wall of the box. Near one end of the box, a transverse cross cut in the top wall cooperates with an auxiliary guide piece which, when placed on the top wall, presents an edge which guides the saw shoe transversely over the top wall and enables a 90.degree. cut to be made in the wooden strip. An opening in the medial region of the top wall affords finger access to the molding or other wooden strip for steadying purposes during making either a 45.degree. or a 90.degree. cut.
