Have you ever picked up your EDC knife for the day and realized it was duller than a trip to the DMV? Sometimes you don’t have time to break out the full fixed angle fancy sharpening system and sit down for a laborious labor of love to get that perfect apex. Sometimes you just want to get your knife back to doing what it’s made to do; cut stuff. Well I have some great news for you! Not only can you serviceably sharpen a knife without specialized tools, you probably have some options for achieving a perfectly usable edge just lying around.
Your Cup of Coffee
No, not the disposable cup from your local mega-chain coffee shop. Your normal every day stained from years of use ceramic coffee cup can actually be used to sharpen. Now, you’re going to be turning the cup upside down, so I suggest one without coffee in it. The bottoms of most ceramic mugs have a ring of exposed medium-ish grit ceramic. This ring can be used very similarly to a sharpening stone or rod. Simply draw your knife’s edge across the exposed ceramic grit at the appropriate angle until you reach an acceptable apex. Make sure there aren’t any oversized pieces of grit in the area you use so as to not create any edge damage, and make sure to use light pressure and a consistent angle. You’ll have a very passable edge and will be ready to pour your favorite brew!
Your Drive to Work
Now, to be clear, I am NOT suggesting you sharpen your knife WHILE driving. That said, when you get in the car to warm it up in the morning you can use the top edge of your window to sharpen. Similarly to a coffee mug, most car windows have an exposed area of fine-ish grit along the top edge. In my experience the grit on this top edge of car windows is significantly finer than that on coffee mugs. So use the same method, but it might take a few more passes and you might be able to achieve a little bit finer edge. Just make sure you do it sitting inside the car, otherwise you might look a little too nefarious; waving your knife menacingly in the window of an empty car. This can be a great way to keep a sharp edge even when traveling!
Your Essential Raiment
If you just need a quick touch up to bring your edge from sharp to razor sharp and wear a leather belt you have a strop at your constant disposal. While it might not make a truly dull knife sharp, a leather strop can be a great way to keep your edge sharp. Even a leather belt can be used as a strop, though I generally recommend using the back / inside side of the belt to avoid any scratches showing. Also, the inside of the belt is sometimes a rougher finished leather, which can be more effective as a strop. To use the strop, find the correct angle for the edge and pull the blade in an edge trailing orientation across the belt with light pressure along the whole edge until the knife is back to your preferred sharpness. If you want to get really wild with it you can even put a very small dab of toothpaste on the leather and smear it around to an even and very thin coating on the area you’ll use as a strop. The toothpaste will provide a little bit of polishing action, not to mention a pleasant aroma.
Dull knives don’t have to be a constant frustration when you’re short on time or specialized tools. With a little ingenuity, you can sharpen your knives using everyday items you already have around the house. Whether it’s a ceramic coffee mug, the top edge of your car window, or even a leather belt, these household items can be employed to achieve a usable edge on your knife. Just remember to use light pressure, a consistent angle, and be aware that these methods should be used as backups when a dedicated sharpener isn’t available. With these simple tips, you can get your knife back to its cutting best in no time.
