Use a Ceramic Mug as a Sharpening Stone
The bottom of most ceramic coffee mugs have a flat, unglazed ring that is the perfect surface for giving that dull knife or blade a quick sharpening. And if you find yourself in need of sharpening a utility knife, pocket blade or scissors and don’t have access to a sharpening stone, you can simply flip over a ceramic coffee mug and use the outer edge of the bottom, the non-glazed part, as an emergency sharpening stone.
Just run the blade across the bottom of the mug at a 45-degree angle, working from the one end of the blade to the tip. Next, slide the blade downward in one direction, keeping your fingers out of the way as you work.
This isn’t a perfect solution for continually sharpening your blades, but if you need to quickly sharpen and clean up the edge of a blade this method will do in a pinch. We do recommend eventually investing in a blade sharpening kit.
