This is a rendition of a Middle Palaeolithic leafpoint. It is made from a toilet cistern, what Americans call ‘Johnstone’. It is obviously flat, and as such similar to tabular flint, or ‘platensilex’. Consequently, it is primarily useful for learning how to shape tools. I think this used to say ‘Haddon’ on the cistern and quite like the way it is still present on this Neanderthal spear point. It is an interesting material to work and very prone to ‘end-shock’. I have five more toilet cisterns stored in our back yard, much to Karen’s chagrin.
