10 Easy Ways to Sharpen a Knife with Household Items

Do you ever find yourself without a sharpener?

Sharpening is something that people do not do often enough. It’s important to know when and why you should be sharpening your knives so that they stay in good condition for as long as possible. 

Sharp knives are safer and easier to use than dull ones. They also make it much easier to slice through food without crushing it. It will give you the best results in the kitchen and with other tasks like cutting open boxes or slicing salami.

You can sharpen your knives with household items such as sandpaper, steel wool, or even the back of a ceramic plate. It’s important to know that not all sharpening methods are created equal.

For example, using sandpaper will take off more metal than other methods and may cause damage to your blade. Be sure to use the right tool for the job!

In this blog post, we are going to talk about how you can sharpen a knife with household objects. 

What is knife sharpening?

The act of using a stone or sandpaper to grind the blade edge of weapons and tools is called sharpening.

As you sharpen, always use gentle pressure with your fingers so that they are never in contact with the cutting surface; this can lead to an accident.

How do you know if it needs sharpening?

Run your fingertips gently over the blade’s edge. An edge that is well-defined and distinct makes a knife feel sharp. In contrast, if the blade feels dull it can be given an edging to make sure you do not waste time with food prep.

10 Ways to Sharpen a Knife with Household Items

There are many household items that can be used as an alternative to a regular sharpener. Here are a few of them.

1. Coffee Mug

If you are not one to keep a knife sharpener on hand, don’t worry! You already have the perfect tool for it in your kitchen.

As any coffee drinker knows, there is usually an uneven surface at the bottom of their cup. This can be anywhere from rough and coarsely ground like sandpaper or fine enough to sharpen knives with ease – depending upon how old your mug may be as well as its use over time.

So how does this work? First, you take a mug and gently rub it on the knife edge. Then use your fingers to feel if there is any roughness left or not. If necessary, repeat until all of the parts that are sharpened have been taken care of by using both sides (the inside) part as well as the outside rim area where most people drink from!

2. Ceramic Plate

The ceramic plate or bowl method is much like the coffee mug technique. You can sharpen a knife on an unglazed surface such as ceramics. This will make it stay sharp without being too rough on the blade.

3. Spine of another knife

You might find yourself in a situation where you have one knife but need to sharpen another. Luckily, there is an easy way with just two knives and some ingenuity!

Hold your second blade at a 20-degree angle over the spine of the first blade while guiding it through. This will create an even cut that leaves both blades sharp for when they are needed again.

4. Nail file

While less popular than the coffee mug, nail files are still a common household item. This is where you sharpen your blades with an old nail file, which has a texture similar to that of sharpening stones.

If all else fails and you’re in need of blade repair while on long hikes or other outdoor excursions, this will be able to save your life before it’s too late!

5. Sandpaper

Sandpaper is an excellent option for sharpening your knife since it is available in different grades so that you can hone the blade of your knives to their maximum potential.

You will need a rough grade of sandpaper at first but then move up to finer grains once the edge has been made sharper. Take care not to rush through this process; highlighting edges takes time and focus.

6. Car window

Car Window

When it comes to sharpening a knife, you often need special things. There is a window method! Pushing your blade along the edge of an unsuspecting car’s windshield will take any dullness away and have that old-fashioned cut back again in no time!

In controlled sweeping motions, move your knife blade along the edge of the glass as you use light and kind of slow strokes.

Since this method isn’t meant for complete honing, it’s going to take a while since you really need to consider whether to buy a new window for your car or have a sharp knife.

7. Nylon backpack strap

A backpack is a must-have for any disaster, and it comes with an extra strap that can be used as a knife sharpener.

To sharpen your blade on the nylon strap, simply rub the knife-edge across the smooth outer surface of the nylon straps. 

If you are using a cutting knife, you should start with the sharp edge and work your way away from you to the unsharpened edge. Repetition of this motion is essential on both sides of the pocket knife.

8. Glass

Glass is a very hard material, did you know? Although it’s easy to break, it can still be tough. The Mohs scale measures the hardness of materials and glass ranks right around steel knives on that list.

You can sharpen with glass if your favorite stones aren’t available or rough enough for what you’re working on.

Just flip any cup upside down so its bottom becomes exposed where coarse circles are usually found, and start sharpening.

9. Shovel


A shovel is another tool that can be used for sharpening knives. You probably realized any hard, coarse surface will sharpen a knife. The bottom edge of the U-shaped section has just that kind of rough edges you’ll need to restore your blade’s condition and get it ready for use again.

10. Concrete

Sharpening on concrete may seem like a strange idea, but during an emergency, there won’t be much time to choose.

Start stroking your knife against the road as soon as you get down there. Though this strategy seems absurd at first glance, remember that nothing is impossible if done right.

Final Verdict

So, there you have it. You can sharpen your knives with items from around the house and save some money in the process.

We’ve provided some tips that should help you get started sharpening kitchen knives with everyday household items in the convenience of your own home. Just remember to take care when using these methods and be sure not to put yourself or others at risk while doing so.
