How is a blade distinguished from other stone flake types?

A blade is distinguished from other stone flake types primarily by its specific width and length ratio, which is generally defined as being longer than it is wide. This characteristic is essential in lithic analysis because it reflects the method of production and the intended use of the tool. Blades have a length-to-width ratio of at least two-to-one, indicating that they are more elongated compared to other flakes.

This specific measurement allows archaeologists to categorize and analyze artifacts more accurately, as it signifies not only the morphology but also the potential applications of the tool in prehistoric contexts. Understanding this distinction helps in reconstructing the technological capabilities and behaviors of past human populations based on their tool-making practices. In contrast, other flake types do not adhere to this strict ratio and can vary widely in their dimensions. Recognition of blades versus other flake types is vital for drawing inferences about cultural practices and technological advancements in ancient societies.
