ABSTRACT:
A quick-availability scribe utilizes a body having a generally rectangular center format, each corner of the rectangular format extending to a curved space along the ends of the body to define a number of curved slots. Each curved slot has a first side perpendicular to an adjacent side edge, an inward curving middle extent, and a second side terminating at an acute angle to form an acute angled edge extending across the thickness of the material. Adjacent slots at one end of the body may share an outward curved transition extending between their acute angled termination edges of their second sides, but any shape transition may be used. Up to four slots can be accommodated while keeping an overall generally rectangular or square format. It is preferable to arrange adjacent slots at the end of a generally rectangular body to skip the next most adjacent scribing magnitude in order to avoid invading too much of the material forming the transition extending between the acute angled termination edges.
