Balasiong

Balasiong (also spelled balacion, baliciong, or balisiong) is a Filipino sword used by Muslim Filipino ethnolinguistic groups (the Moro people) in the Southern Philippines. It is a type of kalis but differs in that the double-edged blade isn't straight or wavy but instead slightly convex. It also tapers sharply to the tip. The hilt is slightly curved, an element known as the kakatua (cockatoo).
