Not long ago, an online user posted a photo of a curious metal tool with a design that looked both intricate and practical.
“[What is this thing?] Found it while cleaning out grandma’s house,” wrote one Redditor, inviting others to join the digital hunt to identify the strange object. “She had it in her kitchen, we assume it is some sort of can opener multitool but have no idea how it would be used.”
Within hours, comments poured in. Some users suggested it might be a 19th‑century can opener, while others thought it could be a multipurpose tool for fishing or camping. A few even joked that it could double as a weapon.
“I’m not a food container expert so I wouldn’t know,” one netizen admitted, giving up quickly. Another offered their guess: “Old school can opener… puncture into can and lever forward one step at a time to cut the top off.” They added, “Makes great jagged edges you can cut yourself on and get tiny metal shards into the contents.”
A third user, referencing the tool’s sharp edges, shared, “Still have a scar where it slipped and embedded in my arm when younger!!!”
“I’ll never forget [when] this went right through my hand trying to open tin,” another recalled.
The primitive‑looking kitchen tool is indeed a vintage can opener — one that left plenty of scars on unskilled users attempting to free the contents of a can.
Humble can opener
The story of the can opener begins with canned food, which existed long before anyone figured out how to open it easily.
Early cans required brute force, and it wasn’t until 1858 that American inventor Ezra Warner created a tool designed to pierce can lids. Shaped like a lever with a curved blade, it was clunky but effective. The U.S. military used it widely during the Civil War, though it wasn’t ideal for home kitchens.
In 1870, William Lyman transformed the can opener with a rotating cutting wheel, making the process far easier and safer. His design laid the foundation for modern can openers, though it still required some skill and strength.
Can openers through history
- Lever‑type opener (1858): Ezra Warner’s original design, used mainly by the military.
- Rotary opener (1870): William Lyman’s cutting‑wheel innovation.
- Keyed cans (1900s): Built‑in keys for rolling back lids (like old sardine cans).
- Electric openers (1930s): Bulky but groundbreaking automation.
- Ergonomic handheld openers (1950s): User‑friendly and efficient.

Today
Can openers have evolved dramatically thanks to technology, making it easier than ever to break into cans — yet many people still swear by the old design.
“Wanted to buy a new one, you cannot find them now,” one Facebook user wrote. Another added, “Still the best can opener!!”
A third chimed in, “I still have one and use it on occasion. Dangerous bugger if not used properly.”
