Bolo knife

A bolo is a kind of machete, used particularly in the jungles of Indonesia and the Philippines. Like other machetes it is primarily intended for clearing vegetation (whether for agriculture or during trailblazing). Bolos are also used as military weapons. Such bolo knives were a particular favorite of the Filipino resistance during the Commonwealth period, and during the Philippine-American War.

Bolos are particularly characterized by having a native hardwood handle, a full tang, and by a blade that both curves and gets wider (often considerably so) nearer to the tip. This moves the centre of gravity as far forward as possible, giving the knife extra momentum for chopping difficult vegetation.
