The sandpaper method

Another alternative is to use sandpaper—preferably double zero.

Place the paper on a flat surface like a table. Then run both sides of the knife up and down until it regains its sharpness.

You can also fold the sandpaper in half with the rough side facing in. Stick the knife in and run it through a couple of times. You will notice the difference immediately.

Use some aluminum

If you don’t have sandpaper, aluminum is another option for sharpening your knife. This method to sharpen knives is used on solid blades that need to be sharpened just a little.

Place a suitable thickness of aluminum foil on a wooden board into a ball. Slice this ball several times with the knife.

Then pass a damp cloth over the blade to rid it of steel scraps.

Sharpen the knife on the car window

• Go slowly and go back and forth several times, changing the sides of the knife blade.

Use a leather belt

It’s more of a buffing than a sharpening. But this technique can be beneficial in giving thin, brittle blades a better glide.

Firmly secure one end of the belt under your foot, and hold the other end with your left hand.

With your right hand, quickly rub the blade on the belt. Make several passes in one direction and then the other, respecting an angle of about 30°.

How to Sharpen a Knife at Home With a Stone

Find a piece of granite, marble, sandstone, quartz, or any hard, smooth, flat natural stone.

Flip the knife over and repeat the same process on the other side.
