Best Knife Sharpeners Electric

A sharp knife isn’t just a chef’s best friend; it’s essential for anyone who spends time in the kitchen. Whether you’re an amateur home cook or a professional chef, you understand the importance of maintaining the sharpness of your blades. Not only does a sharp knife make food preparation easier and faster, but it also ensures safety, reducing the risk of accidents. Over time, even the highest-quality knives become dull and require sharpening. While there are several methods to sharpen a knife, this article delves into the world of electric knife sharpeners, highlighting their benefits and introducing you to various types.

Benefits of Using an Electric Knife Sharpener

Speed and Efficiency

Electric knife sharpeners are a boon for those who want quick results without compromising on precision. Gone are the days of laboriously grinding your knife on a stone. With a push of a button, you can have a razor-sharp blade in minutes.

Consistent Results

Consistency is key when it comes to knife sharpening. Electric sharpeners provide the same sharpening angle every time, ensuring that your knife remains uniformly sharp across its entire edge.


Using an electric sharpener is generally safer than manual methods. The fixed angles and secure grip minimize the risk of injuries, making it a suitable option for novices and professionals alike.

Types of Electric Knife Sharpeners

Grinding Wheel Type

One of the most common types, these sharpeners use a rotating wheel to sharpen the blade. They often come with multiple grinding stages, allowing for coarse to fine sharpening, ensuring a polished edge.

Belt Type

Belt sharpeners use a sanding belt to grind the blade. These are especially useful for those looking to sharpen a wide range of knives, from kitchen to hunting knives. They offer flexibility in terms of adjusting the sharpening angle and replacing belts of different grits.

Ceramic Type

Ceramic electric sharpeners employ ceramic wheels or discs to sharpen blades. They are known for delivering incredibly sharp edges and are particularly effective for honing already relatively sharp knives. They’re gentle on knives, ensuring longevity.

How to Use an Electric Knife Sharpener

Safety Precautions

  • Unplug when not in use: Ensure your sharpener is unplugged when you’re inserting or removing knives.
  • Keep away from water: Like all electric appliances, ensure your sharpener is kept away from any water sources to avoid short-circuiting or electrocution.

Step-by-step Instructions:

  1. Preparation: Clean the knife blade to ensure there’s no food residue.
  2. Plug in and power on: Insert the plug and switch on the sharpener.
  3. Insert the blade: Starting from the base, place the knife blade into the slot, ensuring it lies against the sharpening guide.
  4. Pull through: Gently pull the knife towards you, allowing the electric sharpener to do its work. Ensure consistent speed for an even sharpen.
  5. Repeat if necessary: For extremely dull blades, you may need to pull the knife through the sharpener a couple of times.
  6. Clean and store: Once sharpened, clean the blade to remove any filings and store safely.

Maintenance and Care

Electric knife sharpeners, while durable, do require some regular maintenance to ensure longevity and peak performance.

Cleaning the Sharpener

  • After Each Use: Remove any metal shavings or debris. Many electric sharpeners come with removable trays or compartments that catch these particles. Empty and clean them regularly.
  • Deep Cleaning: Every few months, give your sharpener a deeper clean. Unplug it, remove any removable parts, and gently brush or vacuum out any accumulated particles. Some models allow you to remove the sharpening wheel for cleaning – if so, refer to the user manual for guidance.
  • Avoid Liquids: Never immerse your electric sharpener in water or use wet cloths. Instead, use a slightly damp cloth to wipe the exterior, ensuring it’s thoroughly dry before the next use.

Replacing Parts

Over time, the grinding or sharpening elements may wear out. Some models offer replaceable sharpening wheels or belts. Check the manufacturer’s guidelines on when and how to replace them.

Storing Properly

Always store your sharpener in a dry place, away from extreme temperatures. If possible, keep it in its original box or a protective case to prevent dust accumulation.
