Folk Art, Tibetan Phurba Dagger

Phurba (or kila in Sanskrit), a traditional three-sided ritual dagger from Indo-Tibetan Buddhism and Indian Vedic traditions. It is a spiritual implement used to combat negative energies and spiritual impediments. 
 The blade is designed with three facets that meet at a single point, symbolizing the severance of the "three root poisons" in Buddhism: ignorance, greed, and aggression. It is used ritualistically to pin down or destroy these negative forces.
Hilt and Handle: The hilt  features three faces of a deity Vajrakilaya, which can be peaceful, joyful, and wrathful. The handle incorporates a Vajra (thunderbolt) motif, representing powerful spiritual forces and indestructibility. The entire structure is meant to symbolize the axis of the world, connecting the upper, middle (earth), and underworlds.
