A vintage "Tin-Opener" from grandma's era, built on a straightforward concept, is still available today. However, using this tool can be challenging due to its design. To enhance its functionality, replace the rivets with screws, modify the metal plates and wooden handle, and create the knob as an interchangeable part. This allows for easy replacement or sharpening of the cutting edge when needed.
