Stone tools were usually used for stabbing, cutting, scraping, and grinding, but sometimes they served other functions. This gallery includes stone objects of unknown function, or items that do not fit comfortably in the other galleries.

One well-known alternative use for a stone tool is to strike sparks from steel, a legacy that lives on in many modern butane lighters.  The stone part of fire-making kits is referred to as the ‘flint’, or ‘strike-a-light’.  Stone strike-a-lights date back to at least the Chalcolithic, and Otzi—who died around 5200 BP—carried a strike-a-light fire-making kit.  The handles of Danish flint daggers often show damage from their use as strike-a-lights.  Flintlock muskets and rifles rely on gunflints to ignite the powder, and the English closely-guarded their efficient methods of gunflint manufacture during the 18^th and early 19^th centuries.  People still use fire-making kits in various parts of the world, and often recycle a prehistoric flake as the flint.
