Another user described the process: “You had to punch it into the can and lever it forward step by step to cut the top off. It worked but wasn’t for the faint of heart.”

The Invention of the Can Opener
The history of the can opener begins in the early 19th century, but not for the reason you might expect. Canned food was invented decades before anyone thought to create a convenient way to open it. Back then, brute force was often required—think hammers and chisels.
In 1858, Ezra Warner designed the first dedicated can opener, a lever-like tool with a sharp, curved blade. While effective, it wasn’t particularly safe or user-friendly. It was primarily used by the U.S. military during the Civil War.

The real breakthrough came in 1870 when William Lyman invented a can opener with a rotating cutting wheel. This design made opening cans safer and easier, though it still required some effort. Over time, innovations like electric can openers in the 1930s and ergonomic handheld models in the 1950s brought the tool closer to what we use today.
