The "can opener" was invented along with the "can" - cans had to be opened to be of any use! The first cans were invented around 1772 in the Netherlands. Some of the earliest cans were opened with a hammer and chisel. As canning became more popular a plethora of patents were taken out both for the canning process and for various means of opening them. The first can opener patent obtained was in 1855 in England and 1858 in the United States. I recall "keys" were very popular in my youth.
