Below is a link to a very detailed Wikipedia post on Sibat- the spear, as used in the Philippines-
“Sibat is the Filipino word for spear, used as a weapon or tool by natives of the Philippines. The term is used in Tagalog and Kinaray-a. It also called bangkaw, sumbling or palupad in the islands of Visayas and Mindanao.
Sibat are typically made with rattan, bamboo, bahi or other hardwood, either with a sharpened tip or a head made from metal. These heads may either be single-edged, double-edged or barbed. Styles vary according to function and origin. For example, a sibat designed for fishing may not be the same as those used for hunting wild game such as boar.”
