New Mexico designated the bolo as the offiicial state tie in 2007. 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 and Arizona also recognizes the bola tie as a state symbol (the official neckwear).
