A complete flint knife of broad Mesolithic to Early Bronze Age date (10000-1500BC). Knives of this type do not have distinctive period characteristics, with long flakes, unretouched cutting edge, and remaining cortex on the opposite edge present on examples from all periods (see Butler 2005). This example is a concavo-convex knife knapped from a secondary flake with cortex remaining on the right edge and previous long flake removals on the dorsal surface. There is a diffuse bulb of percussion and the small striking platform is still present. The left cutting edge in sharp and unretouc…

A complete knapped lithic implement of Neolithic date (circa 4000-2350BC). The implement is most likely a knife, although could be a small Neolithic hand-axe shaped implement known as an 'Ovate' dating to the Late Neolithic (3000-2350BC). However, the implement is not bifacially worked to the extent expected of an Ovate. The implement appears to have been knapped from a primary flake, from which secondary and tertiary flakes have been removed from the ventral surface. The Dorsal face has been worked to remove cortex on the left medial edge, leaving a substantial amount on the right…
