This is a pristine flint blade made from chert of the Upper Chalk of the North Downs. I found this flint knife while running in a race. It was exposed by rain. I stopped to pick it up. It has the most perfect edge and fine worked surface. Near it were waste flakes of the same grey flint. Was it dropped? Was it part of a burial? Is it Neolithic or early Bronze age? Every time I touch it I'm reminded that, in the landscape my ancestors inhabited they were no less skilful than I am!
