What is the history of the manual can opener?
The manual can opener has a long and varied history that dates back to the early 19th century. The first can opener was patented in 1858 by a man named Ezra Warner, who invented a sharp-pointed instrument that pierced the top of a can and allowed the user to pry it open. Over the years, the design of the manual can opener has evolved significantly, with various inventors and manufacturers contributing to its development.
One of the most significant innovations in the history of the manual can opener was the introduction of the rotating cutting wheel, which was patented in the early 20th century. This design allowed users to easily and safely open cans without having to pierce the top or use a sharp object. The rotating cutting wheel has remained a standard feature of manual can openers to this day, and has undergone numerous refinements and improvements over the years.
