The main importance of the classification of tools and artefacts presented in this book lies in the fact that it helps us plot the world of tools and its evolution in a comprehensive manner with the aid of different artefactual categories. 

The purpose of the classification is to study the organization of the forms of artefacts, the significance of their parts and the basic properties of tools, and to explain the connections and relationships between objects and the environment. The classification describes the most important basic properties of objects. 

It is a good book for designers, design students, researchers, and educators, but also for anyone interested in objects surrounding us.
