File:Bronze Age Hog-Backed Knife (FindID 117042).jpg

English: Part of a triangular perforated knife or hog-backed knife, of late Bronze Age date. The rather obtuse cutting edges are typical of these objects (pers. comm. Stuart Needham). The object would have originally been the shape of a squat isosceles triangle, with the cutting edge on the long side. In the centre there would have been an oval or rounded triangular perforation. The surviving fragment represents less than a third of the original artefact. In its present state it measures 31.31mm in length and weighs 15.99g. The maximum thickness is 6.47mm. The object has a heavy dark green patina with some lighter patches. This knife would appear to have had a lower perforation than most examples, although there is a parallel from the hoard of Bronze Age metalwork found at Eaton, Norfolk (1977, pp. 33-4, no. 86).
