Large khukuri - Janawar Katnu

[Berkley]

Looks like there was something at the throat of the scabbard that came off - perhaps metal decoration?

Possibly, or braided rattan is often employed, but sometimes doesn't take well to the kind of use these kukris get. Here's a specimen (ex JP collection) with an old repair done in waxed twine.
Janawar katne/katnu = animal cutter. Also known as maar hani, meaning something like "sacrificial killing". A search on IKRHS will show some other specimens, and illustrations of the ceremony itself that are not recommended for vegans or the squeamish.
