Abstract: A coiled line tangle inhibitor which comprises a flexible sheath that encases a relatively loosely coiled line to prevent it from tangling with itself as well as tangling with adjacent lines, which also would be sheathed by this invention. The sheath, although very flexible to allow free movement of the coiled line and any attached tool, has sufficient stiffness and diameter so that the coiled line can slide through an open end of the sheath with ease, but without self-meshing, as the line is extended and retracts in normal use.
