ääreltöötatud

ääreltöötatud is an Estonian term that translates to "edge-worked" or "worked on the edge" in English. It is most commonly used in archaeology to describe stone tools that have been deliberately shaped and sharpened along one or more edges for a specific purpose. This process of working the edge distinguishes these tools from naturally fractured stones or those that have only undergone incidental damage.

The techniques used in edge-working varied depending on the material, the intended function of the tool, and the technological capabilities of the people who created it. Common methods include flaking, grinding, and polishing. Flaking involves striking the stone with another object to remove small pieces, creating a sharp edge. Grinding uses abrasive materials to smooth and shape the edge, often for a more durable and less acutely sharp cutting surface. Polishing can further refine the edge, sometimes for aesthetic reasons or to reduce friction during use.

Edge-worked tools are a fundamental aspect of prehistoric technology, found across virtually all cultures and time periods. Examples include handaxes, scrapers, knives, and projectile points. The specific characteristics of the edge-working, such as the angle of the bevel, the presence of retouching (secondary working to maintain the edge), and the type of material used, provide valuable information to archaeologists about the tool's function, the skill of its maker, and the broader cultural context. The study of ääreltöötatud artifacts is crucial for understanding ancient subsistence strategies, technological development, and human adaptation.
