I have this pinahig. In the catalogue of the auction were I won it, it was decribed as Boro (I'm ignorant about Philippines peoples). Looking at
http://www.aiusa.com/medsword/ethswo...gao/index.html
the sheat looks quite similar to the one of the figure 2 Ifugao hinalung. All the pictured pinahigs (always Ifugao), in the same site, have a simple one (with rattan suspension loop). I need your help to clear up, much as possible, about this weapon.
