Before the invention of the can opener, people had to resort to using tools such as hammers, chisels, and knives which posed a potential hazard. The can opener made it much safer and easier to open cans of food.
The earliest recorded patent for a can opener was issued in 1855 by Ezra Warner of Waterbury, Connecticut. His design involved a hand-operated mechanism with two cutting wheels that were used to puncture and cut open both ends of a metal can.
