Method of manufacturing a worked-wire product

A method of manufacturing a worked-wire product, comprising the steps of:

• providing a wire including a core conductor, an insulator surrounding the core conductor, an outer conductor surrounding the insulator, and a sheath surrounding the outer conductor;
• exposing a portion of said outer conductor;
• holding the exposed portion of said outer conductor at least at two positions by at least two adjacent holders;
• bending said outer conductor until said outer conductor is circumferentially cut off, the bending being effected by a repeated bending motion of at least one of said holders about a bending center present between the adjacent holders while applying ultrasonic vibrations on said outer conductor through at least one of the holders;
• removing the cut off portion of said outer conductor to expose a portion of said insulator;
• and
• removing the exposed portion of said insulator to expose a portion of said core conductor.
