Sumpit

Sumpit and sumpitan are general terms for blowguns, usually tipped with iron spearheads, used for hunting and warfare in the islands of the Philippines, Borneo, and Sulawesi.

The blunt end of the dart is capped with a conical plug of soft cork-like wood or wrapped in feathers or plant fiber which is dipped in resin to form an airtight seal when loaded.

[1][2] The darts are too short to cause serious physical injury, thus when used in war or hunting large animals, they are dipped in a cup of poison before being loaded.

The poison is made from the concentrated sap of the Antiaris toxicaria tree (variously known as upas, apo, or ipoh).

[2] War sumpit also typically have iron spearheads attached on one end which allowed their use as spears once their ammunition is exhausted, similar in function to a bayonet.
