"Technique" is the "art" (from the Greek root techne for both words) that makes possible the material culture of mankind. Every mold responds to the original form of the hand, which is the "instrument of instruments," says Aristotle. Eduardo Medrano in The ABC of Tooling brings us closer to the fascinating world of the people who manufacture and deliver molds and dies to their customers. He tells us about the world and national panorama of the companies in the sector, their defining concepts, how a business is model, and what an ideal workshop is like. This book is a guide for those who are starting out in this noble profession and for those who already know it and require specific guidance; it is a book for all those who are curious about the mother of all industries: that of molds, dies and devices.
