Forge Steel Tools

Without them, you cannot cook (or eat), you have no roof above your head, and you cannot go anywhere. Without them, all the machines in this world would stop working, leaving us without water, electricity, and even clean air. Without them, plant and animal life without be impossible, and our own bodies would turn pale and sick and die. Wondering what we are talking about? Metals, dear reader, metals. We make ovens and stoves with metal to cook our food, we build houses with metal parts, and our cars and trains are mostly made of metal. Most machines are made from metal, as are water pipes and air-conditioning plants. No wonder that the life of humans on earth is closely tied to the discovery and use of metals, so much so that we have the copper age, the bronze age, and the steel age as stages of human civilization. Our language is also full of metal talk: strong as steel, bright as gold, and so on.
