"Arivāḷ/vāḷ (Tamil) There appear to be at least two forms of cutting implement known by this name. The Malabar type has the early khaṇḍa hilt form and a blade straight for two-thirds of its length from the hilt and then sickle-shaped. The sword has been classified since the nineteenth century as 'a Malabar temple sword' due to its continued use there. It is the sword of the goddess Bhadrakālī carried by the vēlichapāḍu who officiates in the ritual. Pepita Seth, an expert on the present-day Kerala temple ritual, says that it is not seen south of Malabar."
