Our prehistoric ancestors used flint tools every day; they were of vital importance for cutting and scraping, used for hunting, preparing food, making clothing and building shelters, and their remnants are scattered around the countryside. Unearthing such a find is a magical moment - a direct link to events thousands of years before - but how do you identify the piece of flint you find out in the field? Is it only a lump of flint, or did it really have an important function as a tool prized by our ancestors? And how old is it, exactly? In Flint Tools Field Guide, archaeologist and flint knapper Robert Turner opens a window into prehistoric archaeology, using hand-drawn illustrations and photographs to explain how to identify tools and their uses, as well as approximate their age. This is an important insight into how people lived and worked so many years ago.
