Flint knife or spearhead, often referred to as a Peseshkef knife by Egyptologists. Ripple flaked with finely serrated forked end resembling a fishtail. The pointed end would have been hafted to a handle. An article by Ann Macy Roth in 'The Journal of Egyptian Archaeology' vol. 78 discusses the possible ritual nature of such a tool. Excavated by Professor Petrie at Naqada tomb number 1569 during the winter of 1894-5 for the Egyptian Research Account. Marked in pencil 1569 Neqada. Marked in ink 1569. Also from the same tomb is a flint knife in the Petrie Museum of Egyptian Archaeology, University College London (UC 4825).
