ABSTRACT:
An apparatus for marking and scoring a work object has a first member having a first and second side. A flange is connected to a second side of the first member. A second member has a first edge and a second edge. The second member is connected to extend perpendicularly from the first member. The first edge has a plurality of crenulations extending therealong for receiving an instrument. The flange of the first member is positioned against an edge of a work object and the instrument is positioned between adjacent ones of the plurality of crenulations and against the work object. When the first member is moved along the edge of the work object, the instrument is caused to mark or score the work object along a line parallel to the work object.
