Sheffield's stainless steel legacy

7 January 2013 Last updated at 07:48 GMT

Sheffield cutlery-makers are still producing stainless steel utensils in the same workshop where the alloy was first used.

Cutlery has been made in Sheffield since the 13th century. Harry Brearley developed what is widely regarded as the first 'rustless' or stainless steel there, revolutionising the industry.

Since its inception, the alloy's uses have expanded to include architecture and engineering.
