Binan tribe knives included the handle, blade and sheath and most had straight blades. The sheath would turn up at the end and it would be covered with an embroidered cloth cover, on the bottom of which would be tassels or the hair of headhunted victims. On the handle and sheath were diamond or triangular patterns, similar to those on Paiwan tribe knives. The tribe that used the knife can be identified from the angle of the turn up at the end of the sheath.
