Then, in 1870, William Lyman introduced a rotating cutting wheel. This innovation made opening cans much easier and safer, laying the foundation for the modern can opener we recognize today.
Over time, the tool continued to evolve:
Lever-type opener (1858): Ezra Warner’s original military-style design.
Rotary opener (1870): William Lyman’s cutting wheel concept.
Keyed cans (early 1900s): Built-in keys that rolled back the lid, common on sardine tins.
Electric openers (1930s): A bulky but convenient leap into automation.
Ergonomic handheld openers (1950s onward): Streamlined, safer, and easier to use.
Today’s can openers are far more refined. With improved engineering and safety features, most models minimize jagged edges and reduce the risk of slipping. Some even leave smooth rims that eliminate sharp metal altogether.
Still, nostalgia runs deep.
“Wanted to buy a new one, you cannot find them now,” one Facebook user wrote.
“Still the best can opener!!” another insisted.
And perhaps the most accurate summary came from a third commenter:
“I still have one and use it on occasion. Dangerous bugger if not used properly.”
What began as a simple kitchen clean-out turned into a lesson in culinary history—and a reminder that not all vintage tools were gentle.
So next time you stumble upon a mysterious object tucked away in a drawer, don’t assume it’s junk—or a weapon. It might just be a relic from a time when even opening a can required courage.
