ABSTRACT:
A cylindrical body resembling a piece of pipe has the sharp edge of a utility-knife blade extending into the bore of the body to cut a longitudinal slit in the wall of a piece of plastic tubing that is pushed or pulled through the bore. A removable stop protruding into the bore momentarily stops the piece of tubing until another utility blade, connected to a guide and handle positioned at an angle across the cylindrical body, is pulled into the slitted end of the tubing to cut on a line that intersects the longitudinal slit. A pointed angular piece is thereby cut out and removed to leave in the end of the piece of tubing a notch with a surface slanting outward toward the end of the piece of tubing for functioning as an inclined plane to spread the tubing. A linkage connected between the angular guide and the stop removes the stop to permit completion of slitting. A handle with a triangular blade is also connected transversely to the cylindrical body for cutting the slitted tubing into lengths.
