Singhalese kastane.. Or... is it?

[not2sharp]

This example looks to have been cobbled together from three separate parts:
1) The blade remind me of some post war tourist machetes that used to turn up in the 70s wearing crudely carved round wooden scabbards and handles. IIRC The whole looked a bit like a dha.
2) The guard looks like it was salvaged off a real Kastane
3) The handle looks like it may have once been part of a carving knife set.
