A bolo is a general term for traditional pre-colonial small to medium-sized single-edged swords or large knives of the Philippines that function both as tools and weapons. They are characterized by a wide curved blade that narrows down to the hilt, and comes with a pointed or a blunt tip. Bolos are common tools in the Philippines and are often compared to the machete.

The kampilan is a type of single-edged sword, traditionally used by various ethnic groups in the Philippine archipelago. It has a distinct profile, with the tapered blade being much broader and thinner at the point than at its base, sometimes with a protruding spikelet along the flat side of the tip. The design of the pommel varies between ethnic groups, but it usually depicts either a buaya (crocodile), a bakunawa, a kalaw (hornbill), or a kakatua (cockatoo)..
