A cast copper alloy axe or knife blank / ingot of Chalcolithic / Early Bronze Age date (2450 - 2300 BC). The blank is oval in shape with the butt being rounded narrowed and tapered. In profile it is lentoid in shape and its cross section is a similar lentoid shape. The 'cutting' edge is rounded, from the external edges it tapers gradually until it forms a narrowed but rounded but. There is no sign of a stop ridge or any form of cast design. It is thickest at the mid-point. The surface of the blank is heavily eroded and corroded, small areas of original patinated surface survive but on the whole the surface is pitted and corroded with an eroded surface. It is a dark - mid green colour.

The metallic composition of the knife has been analysed by Dr Eleanor Blakelock, Birmingham Museums Trust. Her report is produced below:

X-ray florescence analysis was undertaken on the surface of the objects using a Bruker M1 Mistral desktop XRF in the Birmingham Museum and Art Gallery conservation laboratory. The results suggests that the axe blank is a copper rich alloy with trace elements of arsenic, antinomy, lead and silver. This composition is typical for an Early Bronze Age date. The analysis however was carried out on the surface of the corroded object therefore the results may not be entirely representative of the core alloy of the dagger/knife.

The form of this blank is similar to a number that Dr Stuart Needham has highlighted in his work on the Early Bronze Age metalwork from the Welsh Marches. Dr Needham was kind enough to examine this artefact and confirmed that he felt it was an unfinished or unworked blank because a) the profiles were unsymmetrical and b) the unrefined shape in plan being sub-trapezoidal or oval in shape c) the xrf results indicate an alloy of early composition.

The axe-blank measures 77.6mm in length, 35.9mm width, and is 5.5mm thick. It weighs 59.87 grams.
