Bow Drill Fire Making
Bow Drill Fire Making is among the most common of primitive fire making skills. Once mastered, it provides an endless supply of one of the basic necessities of life. Without fire you cannot cook food (ok baring you have a bushel of limes lying around in lieu of fire), warm yourself, and in some cases keep predators at bay. It is also one of the single biggest moral boosters whether you are camping or trying to survive in an unfortunate situation.
Bow Drills first appeared in Mehrgarh between the 4th-5th centuries. You may be asking why anyone would want to learn such an arcane method of fire production.
