The Chankas is a Peruvian dance troupe based in Westchester County, N.Y. They perform a highly acrobatic indigenous ritual dance called the Scissors Dance in which two dancers "compete" with one another accompanied by a musical ensemble of violin and harp. The dancers hold pieces of steel in the right hands in the style of scissors, and the scissors act like percussion instruments.

The dancers wear outfits embroidered with golden fringes, multicolored sequins, and small mirrors, but while in costume are forbidden from entering churches because of the tradition that their abilities are the result of a pact with the devil. Regardless, the scissors dance has become a popular part of Catholic festivities. The physical and spiritual knowledge implicit in the dance is passed on orally from master to student, with each cuadrilla of dancers and musicians giving pride to its village of origin."
