Abstract: A cable tie cut off tool including two elements. A first element has a through hole and internal and external threads, the internal threads being configured in a direction opposite the external threads. A second element includes a through hole with a blade at one end of the through hole and the through hole being threaded with internal threads which mate the external threads of the first element. A keyway is in the internal threads of the first element. The internal threads of the first element are designed to cut into but not all the way through a cable tie end to allow the first element to tension the cable tie and then the first and second elements to be rotated together to engage the blade and cut off the tail of the cable tie.

Abstract: A tool is disclosed for tightening and trimming the loop formed by a self-locking strap around a bundle of articles. A strap stop is driven away from the apertured head of said self-locking strap by means of a carrier lever. Bearing against said apertured head is an excess strap cutter either fixed to or ratchetting within said carrier lever. Said cutter severs the excess strap protruding through said apertured head when said tool is rotated so as to engage the cutter blades with said excess strap.
