Abstract
A scribe and a method of using the scribe to mark a cutting guide on one conduit, while also using a second conduit as a guide, is disclosed. The scribe includes a pivot which rests on the outer surface on one conduit. The scribe also includes a scribe element which engages the outer surface of the one conduit. The scribe is moved along the outer surfaces of the two conduits and makes a mark on the one conduit that precisely follows the shape and size of the second conduit. The one conduit is cut along the mark and the second conduit will precisely and accurately fit to the one conduit. A method of coupling two conduits using this scribe is also disclose.
