Hello Roland,
This is an unusual and genuinely old Bugis blade that deserves a dedicated thread for analysis IMHO. A bunch of more pics would be good, too...
The dapur will be a tough call, I guess. The Buginese name for the main pamor along the blade eludes me at the moment - Andi will probably be quicker to supply that. There seems to be a second pamor motif at the base of the blade, too.
BTW, did you apparently sharpened/polished the edges quite a bit, didn't you?
Regards,
Kai
