Bāṛ (बाड़्) is the Nepali word for the blade of a khukurī.1
A number of khukurī types are differentiated by the layout of their fullers, or the absence thereof:
Āṅa (आङ); flat, like a kitchen knife.2
Āṅa khol (खोल् आङ); a single fuller running along the spine. (Commonly called ang khola.)
Du'i cirnu (दुइ चिर्नु); "two split", two fullers in the blade. (Commonly called dui chirra.)
Tīna cirnu (तीन चिर्नु); "three split", three fullers in the blade. (Commonly called tin chirra.)
