How to Sharpen a Knife without Tools


Every now and then, it’s necessary to hone your knives, but you do not have any sharpening tools. The reality is that, even under the most desperate of circumstances, it is feasible to restore razor-sharpness to your knife by using common household objects. So, let’s have a look at How to Sharpen a Knife without Tools!

There are some of these that you might be familiar with, but you might as well learn some new skills.

So, here are seven effective methods for sharpening your knife if you don’t have access to any sharpening equipment.

How to Sharpen a Knife without Using Tools: The Seven Easiest and Most Effective Methods!

Best DIY Working Method to Sharpen a Knife without Tools

1. Make use of a ceramic mug.

We’ll start with a tool that sharpens a knife by removing material off the edge of the blade. Ceramic coffee mugs are widely available in the majority of homes today. It’s as simple as turning the mug upside down and scouring it for the raw area of the cup (which is the rougher section of the bottom that keeps it from sliding around), then slicing it with the knife until you reach the desired edge.

If everything is working properly, you should notice some discoloration on the mug, which shows that the ceramic effectively eliminates steel and sharpens the blade.

2. Making use of a nail file

This one is also highly popular, albeit in a smaller number than the coffee cup. In this one, you’ll be sharpening your blade with your trusty nail file, which you can get from any hardware store.

As you are probably aware, nail files are rather rough in texture, and they are a relatively good depiction of the surface of actual sharpening stones, which are used to sharpen knives properly.

If you don’t have anything else on you, this trick will come in very handy. It can also be used as a small, lightweight makeshift sharpening if you’re going on a long hiking trip in the wilderness, for example.

These are the procedures to be followed:
  • Start by placing your nail file on a firm surface with the rough side of the file pointing up (any hard surface, such as a table or a large rock, will be good support). In order to prevent it from sharpening on your knee, you must take this precaution first. You have some very essential arteries in your thighs that you don’t want to injure at any cost.
  • In the second step of this procedure, take your knife and hold it at a 10° angle to the surface of your file, with the blade pointing away from you.
  • Then, while holding the file in place with your other hand, stroke away from you.
  • Extend your sharpening stroke to span the entire blade length, maintaining the same sharpening angle the whole time.
  • Using the same procedure to sharpen the other side of the blade, lift the knife, turn it over, and bring it back towards you.
  • Repeat until you are satisfied that your knife is sufficiently sharp, keeping in mind to work both sides equally.

3. Making Use of a Leather Belt

Although stropping does not technically sharpen a blade, it helps improve the keenness of a knife by realigning the edge of the blade. It is quick and straightforward to hone a blade with an ordinary leather belt, which you might be wearing right now. Many professionals employ leather straps for stropping purposes.

Check to see that the belt does not have any stitching on it. Move the knife away from the cutting edge a few times to realign the blade.

4. Using a different knife

This method comes in quite handy when you have two slightly blunt knives. Sharpen one blade with the other! When you employ this technique, you are essentially using another knife as sharpening or honing a rod to sharpen the edge of your own knife.

But hold on a sec!

Many people, including knife-making specialists, have told you that you shouldn’t use a knife to sharpen your knife, and you probably believe them. This is because many people perform the task incorrectly.

The majority of people sharpen the blade of their own knife using the edge of another knife. This is incorrect, and it will cause damage to the blades of both knives!

This should be done correctly by using the back of the second knife to sharpen and finish off the blade of the first one. It is considerably more difficult to harm the back of a knife than it is to injure the blade, and even if you do, it is not a significant problem.

So here’s how to go about it the RIGHT way. There are actually two approaches that can be used to approach this trick-

  • Place the knife you wish to sharpen in your left hand and the knife you will use to sharpen the first knife in your right hand. Place the second knife in your left hand and the first knife in your right hand.
  • Rotate the knives so that both blades are towards the right side of the table. In your right hand, take the second knife and position it at a 10° angle to the blade of your first knife. 
  • To sharpen the first knife, stroke the blade with your index and middle fingers, keeping the sharpening angle constant.
  • Flip the knife over and repeat the process on the other side of the blade of the first knife.
  • Repeat the process, keeping in mind to work each side of the blade equally and maintain the exact angle of sharpening during the entire process.

5. Making use of a flat rock

Yes, you may simply use a random stone instead of a sharpening stone. While a sharpening stone will almost always give you a superior outcome, using a flat rock can be an excellent alternative if you don’t have access to a sharpening stone at the time.

This method can be really convenient because it eliminates the need to bring any additional equipment on your backpacking trip.

The key to accomplishing this is locating a great, relatively smooth, flat rock for the project. Utilizing water to lubricate the rock, a popular approach when using sharpening stones, may result in a better result.

So here are the procedures to be followed:
  • Step 1: Locate a smooth, moderately flat rock and thoroughly clean it with water before continuing. Even if it is not unclean, you should wash it with water to moisten, as you would do with sharpening stones.
  • Step 2: The blade of the knife should be placed at a 10° angle to the surface of the rock, with the blade facing away from you.
  • Step 3: Stroke the knife away from you in a single continuous motion, extending the stroke so that it covers the entire length of the blade. Flip the knife over and drag it back towards you, honing the other side of the blade as you are about to finish the job.
  • Step 4:  Sharpen your blade repeatedly until it becomes razor-sharp, ensuring sure to sharpen both sides equally.

6. Making use of a brick

Brick is one of those commonplace items that are pretty similar in function to a sharpening stone.

As with any other sharpening stone, you should treat the brick as though it were a regular sharpening stone, which means that you should employ the same movements and approaches as you would if you were sharpening your knife with actual sharpening equipment.

If you don’t have a sharpening stone, a brick is a relatively simple thing to come by. Choosing a brick that is not too rough is essential, as bricks that are too rough and too hard will cause your blade to deteriorate quickly. For the best results when sharpening your knife at home, look for a block with a “fine-grit” surface.

Let’s get to the procedure-

First Step: Wet the brick you have discovered and lubricate it with it.

Second Step: In step two, place the knife on the brick so that it is at a 10° angle to the surface of the brick and with the blade pointing away from you.

Third Step: Then, in one fluid motion, slide the edge of the knife away from you and along with the brick, maintaining the same sharpening angle throughout the action.

Fourth Step: Adjust the length of the stroke so that it covers the entire length of the blade.

Fifth Step: Lift the knife and turn it over so that the blade is facing you. Repeat the same motion on the other side of the blade to sharpen it.

Sixth Step: Repeat until the edge feels sharp, keeping in mind to work each side of the blade equally and to preserve the same angle of sharpening throughout the process;

7. Concrete

You can sharpen your knife on concrete if you are in a hurry. The advantage of concrete is that it can be found almost anywhere. The drawback is that it might cause harm to your knife, and the conditions must be ideal for it to work.

Use the knife to sharpen it on a piece of concrete that is exceptionally smooth and pass it through it like you would a sharpening stone. Making a few strokes later will make things go a little more smoothly.


Always use caution when holding a knife, regardless of the situation. It necessitates deference. When someone overlooks it, They face horrifying consequences. Maintaining the sharpness of your knives is essential to showing respect for them. A sharp knife is a knife that is safe to use. If you have the opportunity, sharpen your knife using these instructions on how to sharpen a knife without equipment anytime you have the chance.
