How to sharpen a knife without a sharpener


The last thing that people want when they are in the kitchen is to cut themselves by trying to chop with dull knives, which is why it’s important to keep them sharp. And of course, to make life easy for you in the kitchen.

Sharp knives are also more effective at cutting through whatever you are chopping, which will allow you to get dinner done faster. Have you checked our guide about knife sharpening for beginners?

If knives are not sharpened, they will not perform as well and may even be dangerous to use. Dull knives will put extra pressure on the body and grip of a knife, which can lead to cutting oneself or an uneven cut. A rounded edge on a blade may also cause problems with slicing and dicing certain foods.

Sharp knives will also allow you to chop faster and more efficiently as well, so it’s definitely worth the effort! With a knife sharpener, you can turn a sharp blade into a lethal one that will take care of whatever you need to slice and dice.

So how do you sharpen your knife without a sharpener?

That’s easy-just try these methods out!

1) Sharpen it using a stone that can be found outside: Lay the blade flat on the stone and hold it in place with your thumb or fingers of one hand while using the other hand to push down on the blade to create a back-and-forth motion. (Don’t use your precious countertops even if they are made of stone, this creates ridges that you might not love in your precious countertops)

2) Sharpen your knife using glass but BE CAREFUL: Repeat the same process with the glass, but try not to press down on it too much or you risk breaking it and hurting yourself!

3) Sharpen your knife using a Banana (Yes you read it right, a banana is a great knife sharpener in a pinch): Take a ripebanana and carefully use its skin to sharpen your blade while it’s flat against the skin.

4) Sharpen your knife with Wood: Lay the knife on a piece of wood and move it back and forth, which should create grooves in the wood that will act like your sharpening stone!

5) Sharpen your knife using Leather: Take any leather material you have and use that as your stage to create those same grooves in it to sharpen the knife!

There are still more options if these 5 don’t work out. The next steps require a bit of extra effort, but they might be worth it to you!

6) Pass the knife through sandpaper or an old belt: Pass the blade of the knife through sandpaper or an old belt, which will create a rough surface that will help sharpen your knife.

7) Sharpen your knife with a porcelain mug: This one requires a bit of explanation, but it’s actually an effective way to sharpen your knives without a knife sharpener. Take a porcelain mug or other flat-bottomed dish and place that under running water to wet the surface. Get the blade of the knife wet as well, and then drag the knife through the bottom of the mug a few times to sharpen it.

8) Sharpen your knife using a Nylon Strap: Find a nylon strap of any kind and cut the nylon into small pieces that you can hold with your fingers or put on something else that will allow for gripping while cutting through the strap. Keep the knife-edge facing down and cut the strap away from you first, then turn the blade over to pull it back through.

After you have tried one of the above methods, you should notice a considerable difference in how sharp your blade is. It may take time for each method, so be patient and try them all out until you find the best one for you.
