Abstract
A plurality of beads with matching transverse faces and longitudinal bores cooperate to form a bendable shaft with a duct therethrough, held in face-to-face contact with a plurality of elastic bands within the duct. Alternatively, the plurality of bands may comprise a single elastic inner tube. The elastic bands may also mutually overlap to provide redundancy in case a band should break.
