Although preservation of food using tin cans had been practiced since at least 1772 in the Netherlands, the first can openers were not patented until 1855 in England and 1858 in the United States. These early openers were basically variations of a knife, though the 1855 design continues to be produced.

A can opener (North American and Australian English) or tin opener (British English) is a mechanical device used to open metal tin cans.
