Tiger tail wire (also called tiger tail or tiger-tail) is a thin wire encased in nylon often used in beaded jewellery, and particularly suited to stringing heavy beads and sharp beads, which tend to fray other kinds of thread. For this reason, tiger tail is the thread of choice for gemstones. Some tiger tail has multiple intertwined wire threads under the nylon coating. The wire threads are made of stainless steel.
