A Common UK fieldwalking find - a fairly crudely finished thumb scraper of the Neolithic period. A flake tool of dark grey/mottled flint, most likely sourced from a local supply of nodular flint.
The retouch applied to the tool is crude, but fairly extensive - the majority of the tool margins are percussion flaked, and there may be evidence of use wear at intervals along the margins. Plano-convex in section and retaining granular cortex over approximately 15% of its surface, this tool was probably discarded after extensive wear at the distal end caused a sudden and quite common failure that rendered the tool almost useless. In an area replete with suitable raw materials, this piece would have likely been swiftly discarded.
