Do you know?

Steel was expensive and was only used where nothing else would do, particularly for the cutting edge of knives, razors, swords, and other tools where a hard sharp edged was needed. It was also used for springs, including those used in clocks and watches.

Since 1850

Steel has been easier to obtain and much cheaper, and it has replaced wrought iron for a multitude of purposes. It continues to be used in many situations, though the new availabilty of plastics during the 20th century has meant that it has ceased to be used for some.
