Can opener

- Apr 30, 2018-

  Whether electric or manual, mechanical can openers consist of the same critical operational parts. The basic parts hold the can steady—whether by hand or with a mounted or built-in base--and cut the can open, which makes accessing the contents of metal cans much easier. The first can opener, which punctured the can's metal top, was designed in 1858. The device we all know today with a round knife was invented in 1870 and allows for a continuously smooth edge on the lid; nearly 60 years later, the first electric can opener was invented.
