The first such tool popped up in 1858, almost a half century after the can was invented, when Ezra Warner patented the first dedicated can opener. This design became known as a “bayonet and sickle” type can opener. It worked by puncturing the can with the bayonet portion, and then the sickle portion would remove the lid. The opener left extremely rough edges and so never really caught on, long-term.
