A dull knife can make cooking a frustrating task. It slips more easily and requires more force to cut. This makes your work in the kitchen slower and less safe. An electric knife sharpener offers a simple fix to this common problem.
What Is an Electric Knife Sharpener?
An electric knife sharpener is a kitchen tool that uses power-driven abrasive wheels to sharpen knife blades. You plug it in, turn it on, and pull your dull blade through slots that guide it across the sharpening wheels. The process takes just seconds per knife.
The Presto EverSharp electric and similar models have made knife care much easier for home cooks. These tools have changed how we maintain our cutting tools.
How Electric Knife Sharpeners Work
Electric knife sharpeners use spinning abrasive wheels or belts to remove small amounts of metal from your knife blade. This creates a new, sharp edge. Most models plug into a wall outlet and have one or more slots for different sharpening stages.
When you pull your kitchen knife through the slots, the machine guides it at the perfect angle. This is a key benefit over manual sharpening, where getting the angle right takes skill and practice.
The Work Sharp knife systems use belts that work like those in professional sharpening shops, but in a smaller, safer design for home use.
Benefits of Using an Electric Sharpener
Why choose an electric sharpener over manual options? Here are the main benefits:
- Speed: Sharpens knives in seconds rather than minutes
- Consistency: Creates the same edge angle every time
- Ease of use: Requires no special skills or training
- Versatility: Many models can handle different types of knives
- Safety: Guides protect your fingers from the blade
The EverSharp by Presto makes knife sharpening so simple that you’ll likely sharpen more often, keeping your knives in better condition year-round.
Types of Electric Knife Sharpeners
Not all electric sharpeners are the same. Here are the main types:
Single-Stage Sharpeners
These basic models have just one sharpening slot. They work well for quick touch-ups but may not handle very dull or damaged knives well.
Multi-Stage Sharpeners
These more comprehensive tools have two or three slots:
- Coarse (for very dull knives)
- Medium (for regular sharpening)
- Fine (for polishing the edge)
The Chef’s Choice knife sharpeners typically feature this multi-stage design, which helps create a more refined cutting edge.
Professional Models
Higher-end sharpeners like some Chef’s Choice models use diamond abrasives and precise angle guides. These create edges that match or exceed what professional knife sharpeners can achieve by hand.
Popular Brands and Models
Several brands have earned strong reputations in this market:
Chef’s Choice offers premium models with diamond abrasives and multiple stages. The company focuses on precise angles and excellent results. The Chef SChoice 320 model is especially popular for its value and performance.
Presto makes affordable sharpeners like the Presto EverSharp electric model that work well for basic kitchen needs. They cost less but still sharpen effectively.
Work Sharp systems use flexible belts instead of wheels. This design can sharpen many tool types beyond kitchen knives, making it a versatile tool sharpener for the whole home.
What Knives Can Be Sharpened?
Most electric sharpeners work well with standard kitchen knives including:
- Chef knives (the workhorse of most kitchens)
- Utility knives
- Paring knives
- Slicing knives
Some models can also handle serrated knives or scissors. However, most electric sharpeners are not designed for:
- Very thin Japanese knives
- Specialty blades with unusual angles
- Ceramic knives
Before buying, check if your kitchen knives are compatible with the sharpener you’re considering.
How to Use an Electric Knife Sharpener
Using these tools is simple, but proper technique helps get the best results:
- Place the sharpener on a flat, stable surface
- Turn it on
- Hold your knife handle firmly
- Place the blade in the slot nearest the handle
- Pull the knife through slowly and steadily
- Repeat 2-3 times per side
- Move to finer slots if using a multi-stage sharpener
Always pull the knife toward you (not push away). Let the machine do the work don’t press down hard.
The EverSharp and similar models make this process nearly foolproof, which is why they’ve become so popular in home kitchens.
Maintenance and Care
Electric sharpeners need little maintenance. Simply:
- Wipe the exterior with a damp cloth when needed
- Empty any metal shavings collection trays
- Keep water away from electrical components
- Store in a dry place
Most quality models like Chef’s Choice knife sharpeners will last many years with proper care.
Choosing the Best Knife Sharpener
When shopping for the best knife sharpener, consider:
Your Knife Collection
Do you have expensive chef knives that need precise care? Or basic kitchen knives that just need functional edges? Match your sharpener to your needs.
Sharpening Stages
More stages generally mean more refined results. The Chef SChoice models with three stages create polished edges, while simpler models focus on basic sharpness.
Angle Options
European knives typically use 20-degree angles, while Asian knives often use 15-degree angles. Some sharpeners handle both, while others specialize.
Budget
Prices range from under $30 for basic Presto EverSharp electric models to over $200 for premium options. More expensive doesn’t always mean better it depends on your needs.
Space
Consider counter or storage space. Some models are compact, while others take up significant room.
The Advantage Over Manual Sharpening
While traditional whetstones offer great control, they also require significant skill. Electric sharpeners provide consistent results without the learning curve.
The Work Sharp knife sharpening system bridges this gap by offering some flexibility while maintaining ease of use. It’s popular among cooks who want some control without mastering manual techniques.
When to Sharpen Your Knives
Most home cooks should sharpen their knives every 3-6 months, depending on use. Signs that sharpening is needed include:
- Difficulty cutting through tomato skin
- Slipping when cutting onions
- Crushing rather than cutting herbs
- Needing more pressure to slice
Regular maintenance keeps your kitchen knives performing their best and actually extends their life.
Beyond Kitchen Knives
Some electric sharpeners, especially the Work Sharp models, can sharpen more than just knives. They work as a versatile tool sharpener for:
- Garden tools
- Scissors
- Hunting knives
- Workshop tools
This versatility makes them valuable beyond just kitchen use.
Safety Considerations
Always follow these safety tips:
- Keep fingers away from the blade and slots
- Never force a knife through too quickly
- Unplug when not in use
- Keep away from water
- Follow the manufacturer’s instructions
The guided slots on most electric models make them safer than manual sharpening methods.
Summary
An electric knife sharpener offers a fast, easy way to maintain your cutting tools. Models like the Presto EverSharp electric and Chef’s Choice knife sharpeners have made knife maintenance accessible to everyone, not just professionals.
With the right electric sharpener, you can keep your chef knife and other kitchen knives razor-sharp with minimal effort. This makes cooking more enjoyable and safer. The best knife is always a sharp knife, and an electric sharpener helps ensure yours stays that way.
