Hi all, I happen to stil have a pic of 'd big brother' (Visayan) of what I thought it resembles. Although I can already here the comments; 'the scabbard is totally different' , 'this bolo has a metal ferrule on the handle' etc, it is especially the very diminutive angle the blade gets after a certain point which is so characteristic of the knifes from this region; real nasty stabbingpoints.
Though the 'reckognitionpoints' (forms) are not so clear indeed; he shape of the handle is not carved so precisely like the bolo from the pic as is also the simple sheath, hence the confusion.
But the discussion is still open . . . . . .
BTW that wire does look like silver to me . .??? Is it?
