Plano-convex knife, reshaped from an earlier (most likely Neolithic) hard hammer struck tertiary blade-like flake; the original surfaces of the earlier struck flint are patinated (to the dorsal face) slightly misty blue grey with the occasional spotty iron stain, the ventral face is much paler where the patination has leeched in more successfully, much of the lateral edges and the point have been carefully pressure flaked during the Early Bronze Age to convert the flake to the plano-convex knife, These flake scars are neatly flaked in sequence (pattern pressure flaked), especially to o…

A complete flint plano convex knife of early to early middle Bronze Age date, made from a semi circular tertiary flake of dark brown flint, 90.2mm in length. The knife has patches of intrusive low angle pressure flaked retouch on the convex edge and a intrusive and semi abrupt long and short scaled retouch on the straight edge. The distal end appears broken and uneven. The bulbar scar has some low angle removals, but otherwise the ventral surface is unworked.

Plano-convex flint knife, of typical uniface design; the dorsal face is knapped to an asymmetrical leaf shape, unusually in this instance by direct and invasive soft hammer percussion as opposed to pressure flaking, the ventral face is left as struck from the core, the bulb of percussion has a bulbul scar, an indication of being hard hammer struck from the core, most of the platform has been reduced in the process of working the upper (dorsal) face but the point of striking remains extant. Parts of both lateral edges are irregularly “retouched” to an extremely blunt angle and are …

A plano-convex flint knife or slug knife, 81.8mm in length made from a tertiary flake of pale grey flint. The dorsal surface has fiinely worked covering scaled retouch. There is an area of loss to the right side of the proximal end which appears to have been a break in the original flake prior to retouch. The ventral surface is unworked, with a low bulbar scar at the proximal end. Circa Late Neolithic to Early Bronze Age, 2700-1600 BC.

A complete Neolithic to Bronze age Plano convex flint knife. The knife is made from a pale orangy brown translucent flint with inclusions and some cortex remaining on the dorsal face. It is a one sided with a flat ventral face. There is some slight damage to the upper left lateral side of the ventral face. There is no evidence of wear, but both faces have a slightly waxy feel and appearance. The convex dorsal face has vertical knap lines with signs of soft ridging. The left and right lateral sides of the dorsal face seem to show signs of two phases of retouching. The first has semi i…

An incomplete knife probably of plano-convex type, dating to the Late Neolithic to Early Bronze age c. 3300-1000BC. The knife is struck from a tertiary flake and is plano-convex in cross-section. It has covering, sub-parallel flake removal from the dorsal face; short abrupt retouch on one long edge and short semi-abrupt retouch on the other. The ventral face has little retouch, with some irregular semi-abrupt retouch along the same edge as dorsal side. The blade is missing the tip and has two possible opposing notches worked at the proximal end. The flint is dark grey and black…

Dark grey flint with re-formed cortex, possibly collected from the East Coast, plano-convex knife. A short bar-shaped flint with long invasive angled scalar retouch across its dorsal side and with a flat ventral surface. The ventral side of the cutting edge bears a crescentic crystalline hackled zone, and similarly distinctive damage appears along the opposite long edge. The lack of subsequent patination may hint that the object was subsequently incorporated into a sealed deposit. Suggested date: Early Bronze Age, 2350-1600 BC.

Grey flint plano-convex knife fragment. A plano-convex rod fragment with a rounded end at the site of a bulb on its otherwise flat ventral surface. Invasive angled scalar retouch executed from the dorsal aspect appears on the dorsal side; broken recently. The lack of patina may hint this was incorporated into a sealed deposit.

Elongated semi-hard hammer (large bulb, no bulbal scar) struck blade, of unpatinated mid-grey flint with light and dark streak running the length of the flake. Both lateral edges have been extensively pressure flaked to the dorsal face only to form the plano-convex knife, one side has a shallow notch at the midpoint. Early Bronze Age, 2,350 to 1,500 BC.

A complete flint plano-convex or slug knife knapped from a grey flint with pale brown patches. The knife is 86.7mm in length and 46mm in width. The dorsal surface has covering flaked removals with intrusive areas of scaled and angled retouch around the convex curved side and short abrupt retouch on the concave side which suggests that the knife has been backed for use on one edge only. Circa late Neolithic to Early Bronze Age, 2700-1600 BC.

Flint possible plano-convex knife ?fragment. A thick flake with a curving cutting edge along one side; angled scalar retouch executed from the dorsal aspect follows this curved edge. The ventral surface may be trimmed, and a hinge fracture may assist the definition of the putative cutting edge. A flat surface opposite the cutting edge may have been left as a butt to enable pressure to be exerted on it. An origin as a fragment of a polished flint axe might also be considered, in which case the cutting edge was reused. Creamy patina suggests the object has subsequently endured exposure …
