Abstract
Abstract An artwork mat marking and cutting apparatus for use in cutting mat and similar material for picture framing and the like is disclosed. The apparatus includes a combined marking and bevel cutting device and a dual scale conversion ruler for ease of measurement in laying out mat borders. The conversion ruler has a cooperating extension which fits within a grooved guide, the guide having a T square like end for squaring the mat material with the apparatus. The outer borders of the mat material may be cut using a straight cutting device in combination with the above guide. The guide includes a feature allowing the cutter to traverse the entire sheet of material. Both the bevel and straight cutting devices allow the blade to be retracted when not cutting, and have various adjustment and other features. An alternative adaptor provides for the use of the bevel cutting device to make cuts perpendicular to the mat material surface.
