It’s on the underside of our cabinet in the house we recently bought, built in the ’70s. Any ideas what it could be?

Nestled under the kitchen cabinet lies a humble reminder of practical innovation from the 1970s: the under-cabinet jar opener.

With its dull metal teeth, it’s a testament to the durability and simplicity of the past. To use it, simply wedge a jar lid against the teeth until they grip, then twist.

The seal gives way with a satisfying pop, a familiar sound in the backdrop of family kitchens for decades. This tool has outlasted trends, bearing witness to meals and memories created around the kitchen counter.

It’s a slice of history, enduring and reliably simple, serving as a bridge from the self-reliant past to our modern, fast-paced world.
