In this article, we will explore the different methods and tools for sharpening kitchen knives, as well as provide expert tips on how to maintain the sharpness of your blades. Whether you prefer manual sharpeners, electric devices, or traditional whetstones, we’ve got you covered.

Expert Recommendations

We have consulted with John Somerall, a classically trained chef and knife expert, to provide you with the best practices for sharpening kitchen knives. With his expertise and experience in testing various knife sharpeners, you can trust that the recommendations and techniques presented in this article are reliable and effective.

II. Understanding the basics of knife sharpening

How often should you sharpen kitchen knives?

As a practical matter, you should sharpen your main kitchen knives at least once or twice a year, and potentially as often as monthly. You can’t really “oversharpen” a knife, though each round of sharpening removes a little bit more metal. This will eventually wear away enough of the blade that you’ll have to replace the knife, but that will take decades.

How do you get rust off a knife?

You should worry about corrosion before you start sharpening. Soak rusty blades in a bowl of white vinegar overnight (or up to 24 hours). Remove from the vinegar and scrub the rust off with steel wool, a scouring pad, or a wire brush. If the rust is bad enough that it’s eaten all the way through the blade, it’s time to replace the knife.

How do you sharpen a ceramic knife?

“Ceramic knives are much harder than stainless or carbon steel knives. They are great at retaining a sharp edge over a long period of time because they are so hard, but their hardness also makes them more brittle,” Somerall says. “When sharpening a ceramic knife, remember how much pressure you’re applying to the face of the blade and where the pressure or force is being applied.” Ceramic isn’t as pliable as steel, and that makes it easier to chip or snap the blade. For this reason, Somerall recommends using a whetstone. “Use two hands to sharpen a ceramic knife when using a whetstone,” he says. “A diamond stone is better suited for sharpening ceramic knives as diamond stones are harder and make the sharpening process more efficient. Because ceramic knives lack ductility, you won’t notice a burr developing as you sharpen the knife. Instead, you’ll need to rely more on your technique and the final grit associated with your tools to sharpen the knife effectively.”

III. Step-by-step guide to sharpening kitchen knives at home

Using a Manual Sharpener or Whetstone

1. Settle the knife into the coarsest slot of the sharpener. Pull your knife through slowly and with even pressure. Repeat this step three to six times, or more if the knife is especially dull.
2. Repeat this step with the next-coarsest slot, and then the third and finest slot if the sharpener has one.
3. To maintain the blade as long as possible between sharpening sessions, run both sides across a honing steel once or twice before each use.

Using an Electric Sharpener

1. Review the knife sharpener’s instruction manual carefully before beginning.
2. Turn the machine on, settle the knife into the coarse slot and slowly pull it through. Try to maintain a consistent speed and level of pressure across the entire blade. Repeat three to six times.
3. If necessary, turn the knife around and repeat the same motion on the other face of the blade. (Some electric sharpeners sharpen both faces at once.)
4. Repeat steps 2 and 3 using the sharpener’s progressively finer slots.

Using a Whetstone

1. Submerge the stone in water for an hour. This helps lubricate the blade and ensure even sharpening.
2. Place the stone in a stable holder, or on a towel over a cutting board or countertop, with the coarsest side up.
3. Hold the blade at your chosen angle (use the included angle guide to help), and rest the heel of the blade at the bottom of the stone. Maintaining the angle and amount of pressure, pull the blade toward you while moving it sideways from heel to tip. You want each section of the blade to slide against the stone for the same amount of time.
4. Continue pulling the blade across the stone anywhere from 10 to 50 times, depending on how dull the knife was when you started. Periodically pour more water over the stone to rinse off grit and shavings.
5. Flip the knife over and repeat steps 3 and 4 on the other side of the blade.
6. Repeat with successively finer sides of the stone.
7. Let the stone dry completely before putting it away for storage.

IV. Pro tips for achieving a razor-sharp edge

Use the right angle

When sharpening your knives, it’s important to maintain the correct angle. For most kitchen knives, a 15 to 20-degree angle is ideal. This can be achieved by using a sharpening guide or practicing the motion to ensure consistency.

Apply even pressure

Whether using a manual sharpener, electric sharpener, or whetstone, it’s crucial to apply even pressure as you sharpen the blade. This will help to ensure that the entire edge of the knife is sharpened uniformly.

Regular maintenance is key

Instead of waiting for your knives to become extremely dull, it’s best to perform regular maintenance to keep them sharp. Using a honing steel before each use can help maintain the edge and reduce the frequency of sharpening.

Know your knife

Different knives may require different sharpening techniques. For example, ceramic knives require a different approach than traditional steel knives. Understanding the material and construction of your knife can help you sharpen it effectively.

V. Maintaining and caring for your newly sharpened knives

Maintaining and caring for your newly sharpened knives is essential to ensure they stay sharp and in good condition for as long as possible. After sharpening your knives, it’s important to store them properly to prevent them from dulling quickly. Use a knife block, magnetic strip, or blade guards to protect the edges of the knives. Avoid storing them in a cluttered drawer where they can bump into other utensils and become dull.

Additionally, it’s crucial to clean and dry your knives immediately after each use. Leaving them wet or dirty can lead to corrosion and dullness. Hand wash your knives with mild soap and warm water, and dry them thoroughly with a clean towel. Avoid putting them in the dishwasher, as the harsh detergent and high heat can damage the blades.

Furthermore, using a honing steel regularly can help maintain the sharpness of your knives between sharpening sessions. Running the blade across a honing steel realigns the edge and removes any tiny burrs that may have formed during use. Incorporating this practice into your routine can extend the time between sharpening and keep your knives performing at their best.

Tips for maintaining and caring for newly sharpened knives:

– Store knives in a knife block, on a magnetic strip, or use blade guards to protect the edges.
– Clean and dry knives immediately after each use to prevent corrosion and dullness.
– Hand wash knives with mild soap and warm water, and avoid putting them in the dishwasher.
– Use a honing steel regularly to maintain the sharpness of the blades between sharpening sessions.

In conclusion, sharpening your kitchen knives at home is a simple and cost-effective way to maintain their quality and prolong their lifespan. By following the proper techniques and using the right tools, you can ensure that your knives remain sharp and efficient for all your culinary needs.
