Unknown Philippine weapon, cane cutter ??

[kai]

This is Batak (Sumatra), one of the most copied cultures in SEA (for already well over 100 years and still ongoing from places like Medan to Bali).

I would guess the age to be from WW2 to the early 1960's.

The fittings look "modern" - post-WW2 up to recent (if artificially aged). I'm less sure about the age of the blade though (base features may have been added later).

I can't remember having seen any antique example; this doesn't mean much though since not many pieces are likely to have survived...

Try to search museum collections for resembling examples!
