Steel is hard, greyish metal that is highly malleable, especially when subjected to high temperatures. It is mainly used in sharp cutting edges, springs and small objects that can be hand-crafted, instead of mass-produced, due to its' high production cost.
Steel can be acquired by smelting iron ore and small quantities of other metals and chemical substances, such as pure carbon or charcoal. The iron ore is purified of unwanted residues, and then processed further to ascertain the desired qualities.
Compared to the brittle cast iron, steel is much tougher and can withstand much more use than solid iron. It is also somewhat lighter, but much more expensive to produce than iron or bronze.
