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. The catalogue card notes that the colour of the flint is paler at the base and suggests that this might be from the binding protectecting the surface. 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.
