Electric knife sharpeners are a convenient way to sharpen your knives at home. They are easy to use and can quickly transform dull knives into razor-sharp tools, enhancing your cooking experience and making food preparation a breeze. Electric sharpeners use a motor to grind and remove tiny amounts of metal from the blade, exposing a new sharp edge. They typically have multiple stages, with coarse and fine slots, and some even have a polishing stage for a flawless finish. While electric sharpeners are more expensive than manual ones, they are a good investment for those who cook often with expensive knives as they are intuitive, efficient, and require very little skill.

What You'll Learn
Using a manual knife sharpener
- Secure the sharpener to a stable surface - Most manual sharpeners need to be firmly held down onto a table, counter, or stovetop. Some higher-end models may come with a vise to secure the sharpener in place.
- Place the knife against the coarse side - Position your knife at a 15- to 20-degree angle against the coarse side of the sharpener. Some sources suggest a slightly higher angle of 22 degrees.
- Apply light pressure and swipe the knife across the coarse side - Using light pressure, gently pull the knife through the coarse side of the sharpener. Repeat this motion about 10 to 15 times on each side of the blade. This step helps remove any large burrs or imperfections and sets the foundation for a sharp edge.
- Switch to the fine side - After the coarse side, move to the fine side of the sharpener. Repeat the swiping motion about 10 times on each side of the blade. This step further hones the edge, making it sharper and more precise.
- Remove burrs - After sharpening, you will likely feel a burr or fine piece of steel along the edge of the blade. Use a honing rod or a leather strop to remove these burrs and realign any imperfections.
- Maintain regular honing - To keep your knives sharp, it is recommended to hone them multiple times a week. Honing involves using a honing steel or rod to straighten the blade without removing any material. Hold the honing steel and knife at the angles suggested by the manufacturer, and pull the knife along the rod toward the tip. Repeat this process on both sides of the blade.
By following these steps, you can effectively sharpen your knives using a manual knife sharpener. Remember to always handle knives with caution and be mindful of your hand's position to prevent injuries.

Preparing your sharpening stone
Choose the Right Stone
Select a sharpening stone that suits your needs. Stones come in a variety of materials, including natural and synthetic, and can be used dry, with oil, or with water. Waterstones are a popular choice, as they are available in a wide range of grit sizes and can create an extremely sharp edge. Diamond stones are another option and can usually be used dry or with lubrication.
Soak the Stone
If you are using a waterstone, it is essential to soak it before use. Place the stone in a tray, cover it completely with water, and let it soak for at least 45 minutes. This ensures that the stone is fully saturated and prevents it from drying out during sharpening, which could cause scratches or nicks on your knife blades. Oil stones, on the other hand, should not be placed in water as this can damage them.
Prepare Your Work Area
Set up your work area by placing a damp cloth on your work surface. This will help keep the stone in place while you sharpen. If using a waterstone, set it on the damp cloth with the coarser side facing up. Keep a container of water nearby to keep the stone moistened during sharpening.
Determine the Sharpening Angle
Most straight blades are sharpened at a 20-degree angle. To find this angle, hold the knife in front of you with the blade straight up and down (90 degrees). Tilt the knife halfway towards the table to create a 45-degree angle, and then tilt it halfway again so that the blade is about an inch (2.5 cm) above the table. This should give you the desired 20-degree angle.
Lubricate the Stone (if necessary)
If you are using an oil stone, add a few drops of stone oil to the surface of the stone before sharpening. This will help reduce friction and improve the sharpening process.
By following these steps, you will have prepared your sharpening stone and be ready to begin the knife-sharpening process. Remember to always refer to the instructions that came with your specific sharpening stone, as some stones may have unique requirements or recommendations.

How to use an electric sharpener
Using an electric knife sharpener is a simple and effective way to sharpen your knives at home. It is important to read the user manual before operating any new kitchen appliance, as some electric knife sharpeners may have a slightly different procedure and safety precautions.
- Place the electric knife sharpener on a flat surface, such as a kitchen counter with plenty of space.
- Turn on the electric sharpener.
- Dial to your selected knife style, if your sharpener has this option.
- Run your knife through each stage of the electric sharpener. For a 2-stage sharpener, run the knife through the coarse slot first, and then the fine slot. For a 3-stage sharpener, run the knife through the coarse slot, fine slot, and then the polishing slot.
- Glide the knife along the fine side of the sharpener approximately five times on each side.
- To remove the burr from the knife, glide the knife along the burr removal side a couple of times, repeating as needed.
- Check the blade closely to ensure it looks smooth and realigned, without any nicks or gouges.
- Test the sharpness of the blade.
- Wash the knife before using it to remove any metal shavings.
It is important to note that electric knife sharpeners should never be in contact with or immersed in water. Always unplug the sharpener when it is not in use, and empty the receptacles of any built-up metal shavings regularly.

Pros and cons of electric sharpeners
Electric knife sharpeners are a convenient and effective way to sharpen your knives at home. They are easy to use, requiring very little skill, and can sharpen exceptionally dull knives. The slots guide you to use the correct angle, and they are generally safe to use.
However, there are some drawbacks to consider. Firstly, they are another appliance to store, and they can be quite bulky. They are also more expensive than manual sharpeners, whetstones, or sharpening rods. Electric sharpeners are very loud, and some users have reported that they can damage the blade, leaving nicks and gouges.
Another downside is that electric sharpeners offer limited angle settings, with some models only offering one angle setting, which may not be suitable for all knives. This lack of adjustability means you cannot choose between a razor-thin edge or a thicker edge, and you are left with a basic edge in the middle.
Overall, electric knife sharpeners are a good option for those who want a quick, easy, and relatively safe way to sharpen their knives at home, but they may not produce professional results or offer the level of customization that more experienced users may desire.
