ABSTRACT:
A cutting mechanism for accurately cutting a notch in a piece of edging, to permit sharp bending of the piece of edging for a picture or plaque, is disclosed. The cutting mechanism comprises a jig secured to a base member, the jig being dimensioned to receive the piece of edging clamped thereto. A cutting blade is mounted on the base member for reciprocating movement between a first retracted position whereat the cutting blade is remote from the jig and a second fully extended position whereat the cutting edge has passed through the jig. The cutting blade has an inverted "V"-shaped cutting edge comprising two blade portions joined one to the other at a central vertex. A cutting blade guide means retains the cutting blade such that, during cutting of the piece of edging retained in place on the jig, the vertex is disposed at a level between the top surface of the jig and the top surface of the second wall of the piece of edging, so as to thereby permit scoring of the inwardly facing surface of the second wall of the piece of edging. A first blade receiving aperture is disposed in the jig to permit the cutting blade to pass therethrough, and is open at the top to permit the cutting blade to extend therethrough. An actuation handle permits selective movement of the cutting blade between the first retracted position and the fully extended position.
