15 luk Bali?

[David]

Looks like a nicely formed blade, but i don't find the hilt particularly impressive Marco. It is merely a later simplified version that attempts to mimic the pattern formed when the grip on this style was done with woven wire.
I agree with Jean that you most often see this sarong form from Lombok. The blade is a classic Bali form (though 17 luk is more rare), but given the connections between Bali and Lombok i wouldn't count out either as an origin.
I can't quite get a close enough look at this blade to call it old or contemporary, but it does seem to be of good quality.
