A bow drill is a simple tool used for starting a fire through friction. It consists of a flexible bow, a drill (a straight stick), a fireboard (a flat piece of wood), and a handhold (a piece to apply pressure). The bow is used to rotate the drill against the fireboard, creating heat and eventually producing an ember. This ancient technique has been utilized by various cultures worldwide, including Indigenous peoples. The bow drill is effective because it allows for continuous rotation, increasing the chances of generating enough heat to ignite tinder. Mastery of this skill can be essential for survival in the wilderness.
