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.
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.
