Official State Tie of New Mexico
New Mexico designated the bolo as the official state tie in 2007 (New Mexico also adopted an official state necklace in 2011). All Cultural Heritage Symbols
A bolo tie (also called bola tie) is a type of necktie consisting of a piece of cord or braided leather with decorative metal tips secured with an ornamental clasp or slide. Boleadoras or bolas (from Spanish bola, which means "ball") are throwing weapons made of weights attached to the end of cords.
Bolo tie slides and tips in silver have been part of Hopi, Navajo, and Zuni silversmithing traditions since the mid-20th century. Bolo ties are widely associated with Western wear (the "bola tie" is also an official symbol of Arizona - the state neckwear).
