Goodness sake. By the time I purchase a dremel, file/ knife honer, wire and a heat gun, I mine as well skip it and use the money saved to purchase a Spring Potato Slicer. 🤭
Why did you go to the trouble of making a plastic covering for the opposite end? It doesn't do anything. 🤔 The biggest disadvantage of using a tin can is, you have to keep it totally dry, otherwise it rusts VERY QUICKLY. I mean you would have to wash and DRY it IMMEDIATELY after using it, or it could be rusted by the time you finish cooking and eating your potatoes! 😝
