Blacksmiths used bronze, and later iron ore, to create swords, plows, axes, and other tools. They used billows made of animal skin to blow air into their fires to produce the heat needed to work with the metal. After heating the metal, they used hammers to shape it into a weapon or a tool.
Blacksmiths started a long time ago. Maybe even when the first person was alive like the cave man they make weapons. That was in the Bronze Age but blacksmith improved after years they made better and stronger weapons.
The skills probably began in what we call the "Iron age". Someone obviously discovered that some types of rock would give up a substance when exposed to high heat that would become solid when cooled. This substance could be used to make simple tools like knives and scrapers and eventually spear and arrow heads that were much tougher and sharper than stone. A simple process to produce wrought iron, that we now call direct reduction, was in use in the middle East more than four thousand years ago.
A blacksmith was very important because he provided weapons and armour for war and for the soldier that defends the village. Also they make weapons for the people of the town to uses for farming and much more.
Blacksmith are really important people in the Greek colonies back in those days. They get paid a lot about 48 euros an hour they get when they work for the King or emperor.
