These distinctive pieces are called 'pounds of butter' from the often buttery-yellow fabric and their shape resemblance to traditional butter slabs in France; the technique involved the careful formation of a shaped core from the large and naturally occurring flint cobbles, from which were struck one or more long Levallois blades which, in turn, were widely traded and have been found across Europe.
