The Bagobo traditionally uses spears in fighting and hunting deer and wild pigs. Among these four spears, the rightmost, known as the kaláwat is the most effective.
A metalhead is attached by a rope to its long shaft and is pulled out as soon as the weapon enters the body of the animal and the shaft trails behind until it is entangled in some undergrowth.
