Fire-saw

It is typically an object "sawed" against a piece of wood, using friction to create an ember.

[1][2] Two forms of the fire-saw have been documented in central and western Australia.

The other model makes use of the woomera weapon and defensive shield that natives carried.

In the Philippines and Oceania, a fire-saw from bamboo pieces is common.

[4][5] A fire thong is a form of fire-saw, where a pullstring (usually wood fibre or rope) is used to saw.
