What characterizes a pebble tool?

A pebble tool is characterized by its rounded stone cobble with several flakes removed from it. This description emphasizes the essence of pebble tools, which are traditionally associated with early human tool-making practices. The process involves striking the surface of a naturally rounded stone to create sharp edges, which can be used for cutting, grinding, or scraping.

The rounded shape of the tool allows for easy handling and use, reflecting an evolutionary step in the development of technology among early humans. The presence of several flakes removed indicates that the tool has been deliberately shaped through flaking, demonstrating intentionality and skill in tool production.

In contrast, the other options describe different types of tools that do not match the characteristics of a pebble tool. For instance, a large core tool shaped like a pointed oval typically emphasizes the core aspect rather than the rounded nature of pebble tools. A thick flake with steep retouch suggests a specific adaptation for particular functions that are distinct from the general use of pebble tools. Very small blades hafted into handles represent a different stage of tool evolution and complexity, which diverges from the simpler design of a pebble tool created from cobble stones. Each type serves its purpose within the broader archaeological understanding of human technological advancement.
