Denticulate tool

In archaeology, a denticulate tool is a stone tool containing one or more edges that are worked into multiple notched shapes (or teeth), much like the toothed edge of a saw. Such tools have been used as saws for woodworking, processing meat and hides, craft activities and for agricultural purposes. Denticulate tools were used by many different groups worldwide and have been found at a number of notable archaeological sites. They can be made from a number of different lithic materials, but a large number of denticulate tools are made from flint. Due to the nature of denticulate tools they can be difficult to classify, this leads to what is known as a 'typology dilemma'. It can be difficult for archaeologists to sort and classify these tools because it is impossible for them to know if the notches were created intentionally, or if they are a result of unintentional damage. Incorrectly classifying items found at archaeological sites is problematic because it can have a significant impact on how the tools and the site are interpreted by archaeologists. These tools are included in the Mousterian tool industry by Neanderthal culture, proceeded by small hand axes and side scrapers. Denticulate tools have many different uses which can differ based on the material, size and shape of the tool. The tools can be used for woodworking, processing meat and hides, craft activities and agricultural purposes. Experiments carried out by archaeologists found that using denticulate tools "seem to provide more control when working wood than a raw flake or even a scraper might", because they hold their position well on the wood because of the notches. Shaped wooden artefacts have been found uncovered at sites alongside denticulate tools, suggesting these tools were used to shape these items. If denticulate tools are examined under a microscope and traces of use wear may suggest they were used to scrape wood, for example if the edges are more polished and uniform. There is evidence which suggests denticulate tools were also used on softer surfaces such as meat and hides.
