New self-threading cords, tapes, cables and/or ropes (“ties”) are provided, with a plurality of ports through their length. In some embodiments, a perimeter of each of the ports matches at least one first perimeter of the tie, and an end of the tie may be threaded through any of the ports (a.k.a., “self-threading” the tie). In some embodiments, ridges are provided on or about at least part of the tie. In some embodiments, the ridges may be threaded through the ports, and the ridges hold the tie in a fastened position. Due to the plurality of ports and possible self-threading actions, a wide variety of fastening actions may be carried out.
