The object takes its origin from the Vedic era (perhaps, also Vedic), but later found a destination in the context of Tibetan versions of Buddhism and Tantra. In the context of Tibetan Buddhism, Phur-Bu (from Tibet, 'peg' or 'nail') - a ritual dagger, is used to drive out evil spirits. The handle of a dagger with a three-edged blade crowns the horse's head of the fierce protective Tibetan deity Hayagriva. Phur-Boo is also adorned with 'knots' of immortality, the head of Makara - monsters with the torso of a crocodile - and intertwined snakes.
