A Neolithic flint incomplete lithic implement: backed blade dating 3500 - 2100BC. This is the middle section of a robust backed knife; the distal and proximal ends are missing. There are approximately three longitudinal flake removal scars from the dorsal surface. The right edge has been secondarily worked to create the backed edge. There is some use\/damage along the left edge. The flint is a mottled dark grey.<\/p>
