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 suggested a date of Late Neolithic.

Description (Physical description)
Metzger (2017): This artefact is a sub-triangular shaped flint tool that has been bifacially worked. It was made from a grey blue flint with fossil inclusions and some cortex left on the surface with most of the edges polished. This artefact has most of the edges polished but only a few millimetres from the edge; only part of the face is polished. There are multiple step fractures (a flake that ends abruptly with a 90-degree break causing the entire flake to not be removed) on one side. There is a bit of cortex left on the surface, which could mean this tool was made from a flake; the creator tried to remove the cortex but failed and resulted in a step fracture.

Metzger (2017): This artefact fits into Type II of the Polished-edge Discoidal Knife classification. This classification has three types (Type I- circular or D-shaped, Type II- triangular, and Type III- broad leaf to lozenge) and show polished edges. This artefact classification might has functioned as wood or claying working tools. This piece was found in Lakenheath, Suffolk.
