Description (Physical description)
Metzger (2017): This object is a sub-rectangular flint tool that has been bifacially worked. The tool was made off a dark olive flint and has three polished edges. This piece is squarer in shape. This tool has manufacturing features that can be located on the faces; there is step fracture (a flake that ends abruptly with a 90-degree break causing the entire flake to not be removed) and flake scars that run toward the middle of the face away from the edge. The polished edges only extend a few millimetres from the edge. Macro striations can be seen in the polished edges, which identifies the polishing process.

Context (Analysis)
In September 2017 Melissa Metzger, PhD candidate at the University of Bradford, studied a number of polished discoidal knives for their Crowther-Beynon Grant. They supplied further descriptions, measurements, contextual information and bibliographic references. These fields have been updated accordingly. They also noted Burwell should be added to the Place field and suggested a date of Neolithic.

Context (Analysis)
Metzger (2017): This piece falls into the category of Polished-edge Type IV. This category is Clark's Type IV. This shape warrants its own category as the shape is completely different than the others and they are manufactured different as well. The faces and edges of this tool are usually completely polishing with a few exceptions; this tool makes number four in those exceptions. This artefact was found in Burwell, Cambridgeshire.
