I've got to admit to being stumped .
The decoration on the punto does not strike me as quite traditional okir patterns . The blade seems a bit thin for a barung but I have never handled a shandigan so I may well be off on this observation .
What is the material between the ivory and the punto ?
The filework at the forte of the blade is pretty puzzling as it does not quite look like the work seen on tenegre/sansibar/binangon blades .
Maybe we should be looking toward Borneo ....
