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 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
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.
