At first glance, this small metal key might seem unremarkable, but it plays a crucial role in kitchens around the world. Known as the tin can key, it’s a tool specifically designed to open certain types of canned goods, such as sardines and corned beef. Let’s explore the history, functionality, and continued relevance of this modest yet essential kitchen tool.
The Origin of the Tin Can Key
The tin can key was invented as a solution to a growing problem in the early 20th century: how to efficiently open the increasingly popular canned foods. As the canning industry evolved, there was a need for a more practical and user-friendly method to access the contents of cans, particularly those with tightly sealed lids that traditional can openers couldn’t handle effectively
How the Tin Can Key Works
The tin can key operates on a simple mechanical principle, making it easy to use. Here’s a step-by-step guide on how to use this handy tool:
- Locate the Tab: Most cans that require a key will have a metal tab or strip attached to the lid or side seam.
- Insert the Key: Place the slot in the key over the tab. The key should fit snugly, ensuring a firm grip.
- Start Twisting: Begin turning the key, wrapping the metal strip around the key as you twist. This action rolls back the metal strip, cutting open the can.
- Continue Until Opened: Keep twisting until the can is fully open, allowing access to its contents.
The Importance of the Tin Can Key
Despite advancements in can opening technology, the tin can key remains a useful and reliable tool for several reasons:
- Reliability: The key is a simple mechanical tool that doesn’t require batteries or electricity, making it dependable in any situation.

Watching a parent or grandparent skillfully use a tin can key is a common childhood memory for many people, adding a touch of sentimentality to this practical tool.

While modern can openers are more common today, the tin can key still has its place, especially for specific food items. Certain brands of sardines, corned beef, and other canned goods still come with keys attached.
