It's happened to all of us, no matter how cheap or expensive your kitchen knives are. You have found the perfect recipe for supper, you have all of your ingredients ready, your cutting board is clean and prepped, and your knife is so dull it won't cut hot butter.
You rummage around in your kitchen drawers to find a knife sharpener and realize you never got around to buying one. Don't worry! You don't have to angrily hack at your veggies and wind up with a huge mess. All you need to put a nice edge back on that knife is..... wait for it..... a coffee cup! That's right. A coffee cup.
Now, take a look at how dull my poor knife was. I was pressing so hard on that tomato it caused a few wrinkles. How can I make a proper tomato sandwich with such a dull blade?
Like I said earlier, the only thing you need to sharpen a dull knife is a coffee cup. A standard, ceramic coffee cup. Most cups should work, but just to make sure, turn yours over and look at the bottom. There should be a ring of exposed ceramic that has no paint or glaze on it. This is what you're looking for.
You want to place your coffee cup upside down on a stable surface. Hold the cup securely with one hand. Starting with the part of the blade that is closest to the handle, hold the knife at a 45 degree angle, and slowly but firmly drag it across the exposed ceramic. Do this for 4 to 5 strokes on each side of the blade. This should put a pretty sharp edge on the knife for you, but depending on how dull the blade was to begin with, you may need a few more strokes.
