Abstract: A portable and adjustable cutting guide especially designed to minimize chipping of the cut edges on cuts made cross-grain on doors, panels or the like when utilizing a circular saw, a jig saw or a router. The device includes a thin, rigid, preferably plastic, rectangular plate having one long, perfectly straight edge defining a cutting guide line and a slightly raised surface member extending parallel with but spaced from the edge defining the cutting guide line, the raised surface member functioning as an edge stop for the platform of the saw being used with the guide. Preferably the plate is provided with at least one clamp on the opposite side thereof from the edge defining the cutting guide line to permit securing of the plate to the work piece so that it presses down on the surface being cut to minimize chipping thereof. The cutting guide device may also be supplied with a power supply box to facilitate use of the cutting saw and, if desired, with a work light to illuminate the cutting area.
