phurba (kila) (skt. कील kila iast; tib. ཕུར་ བ, vaili phur ba; "kol" or "nail") - a ritual dagger or stake, usually with a handle in the form of three heads of an angry deity and a three-edged blade, probably , intended for stabbing the victim during the rituals (according to some sources, it was used as a nail to bind a ritual victim, but there are also other versions of the purpose). 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.
