Ethnographic folding knives

[asomotif]

but my guess is that it is a carpet maker's knife.

Dear Alan,

I have had one of these too and was told it was from eastern India.
The seller traveled to India and eastern asia regularly to buy his stock.
They told me that it had something to do with cleaning coconuts, but it I can imagine that the construction is a bit to fragile for that job.
Any guess is worth as much as mine.
