ABSTRACT:
A mat cutter employing a razor blade and providing protection against the blade's bending towards either of its sides. The cutter, used for preparing mats for photographs and other art objects, has a base upon which it sits and a section which slopes upward. A holder for a razor blade pivotally attaches to the sloping section and can rotate the blade into and out of a cutting position. When in its cutting position, the blade fits inside of a slot in the base and extends beyond only enough to effect the 45.degree. desired cut. The two sides of the slot prevent the blade from flexing towards either of its flat sides. With the blade thus surrounded and hidden from view, the cutter also employs a marking device that allows the proper placement of the cutter from a mat's edge to cut along a desired line. The cutter also includes starting and stopping marks so that it may produce a cut of the desired length using similar lines along the other sides of the mat. A long straight guide may find use with the cutter to keep its blade on a straight line. A clamping device limits, but does not prevent, freedom of movement of the bar. It does, however, allow the operator to hold it in place using only one hand. The cutter and the guide have interlocking grooves and ridges which keeps the cutter on a straight line without wearing down the edge of either.
