A primitive tool for making fire by rapidly rotating a wooden stick against another piece of wood using a bow-like device.
From 'bow' (the curved tool) plus 'drill' (a rotary tool). This ancient friction-fire method dates back thousands of years across multiple continents.
The bow drill is one of humanity's oldest technologies—friction creates heat, and heat creates fire without a single match! Indigenous cultures worldwide invented this independently, showing how the same problem sparks the same solution.
