Abstract
Abstract A tool useful for marking and constructed of a flexible material which includes a flat member having a structural layer of a predetermined shape with first and second parallel surfaces, the structural layer having marking edges perpendicular to the first and second parallel surfaces for measuring, aligning and marking, a first wear rim along the marking edges extending a uniform distance away from the first parallel surface of the structural layer, a second wear rim along the marking edges extending a uniform distance away from the second parallel surface of the structural layer, a plurality of first marking indicia on and extending away from the first parallel surface along the first wear rim, a plurality of second marking indicia on and extending away from the second parallel surface along the second wear rim, wherein the first wear rim extends away from the first parallel surface a greater distance than the first marking indicia extend away from the first parallel surface, and wherein the second wear rim extends away from the second parallel surface a greater distance than the second marking indicia extend away from the second parallel surface.
