Kã̄jo (काँजो) is the Nepali word for the bolster of a khukurī.1
It literally means: "A band of metal (e.g. round the handle where the blade of a khukri or sickle is sunk into it); hilt of a khukri or sword."
khukurī bolsters are usually made of iron, but precious metals like silver and gold are also encountered on higher-quality pieces.
