A strange, weapon-like object found in a kitchen drawer sparked a viral mystery online after a Reddit user shared a photo from their grandmother’s house. Many were confused, while others instantly recognized the sharp metal tool — and even shared injury stories.
The surprising answer? A vintage can opener.
This old-style opener punctures the lid and slices it off step by step, often leaving jagged edges. Several users warned how dangerous it could be, recalling cuts and scars from using it.
The tool traces back to 1858, when Ezra Warner created the first can opener for soldiers. In 1870, William Lyman improved it with a rotating cutting wheel — the foundation of modern designs.
Today’s can openers are safer and easier, but this vintage kitchen tool proves that everyday objects can carry surprising history — and a few sharp memories.
