A fire plough (left), as opposed to a hand drill (right).

A fire plough (or fire plow) is a primitive tool to create fire. In its simplest form, it is two sticks rubbed together.^[1] Rubbing produces friction and heat, and eventually an ember.^[2] More advanced are "stick-and-groove" forms, which typically uses a V-shaped base piece of wood, and a "friction stick" as the activator.^[2][3]
