Hand tool - Hand tool - Iron and steel tools: Iron technology was derived from the known art of reducing copper and bronze. The principal requirement was a furnace capable of maintaining a reducing atmosphere—i.e., one in which a high temperature could be maintained from a good draft of air. The furnace had to be tall enough to allow the iron to drop from the smelting zone and form a slaggy ...

The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items. It is the most-used metal by both tonnage and purpose.

In Northern and Northeastern Europe, bogs were the site of bog iron, the earliest form of iron used for tools. Iron compounds from plant decay precipitate out and are deposited at the bog bottom. These nuggets of iron were harvested and smelted to produce mining tools of wrought iron. Some people harvest iron in this manner to this day.
