A huge collection of different types is available there in the market. In order to pick your electric knife sharpener, you must go through all the categories carefully.

Some of them pull double duty and offer both the services of sharpening and honing. Different brands use different sharpening agent but most of them prefer diamond plates as sharpening agent.

Why Dull Knife is Dangerous

Ceramic, titanium and tungsten carbide are the other material used in the newer model of sharpeners.

Although a lot of electric knife sharpener reviews suggest that sharpeners with diamond plates create the sharpest edge with great precision. A double sided sharpener is a far better choice than single sided sharpeners because it is specific and much quicker.

2. Value Features

An automatic knife sharpener will have the ability to sharpen household items like razor blades, axes, gardening tools, lawnmowers and scissors other than just the knives.

A sharpener offering a variety of angle settings to adjust your knives perfectly is definitely worth looking for. Remember that only a few high quality sharpeners are capable of sharpening all types of knives including butcher, fillet and serrated ones.

Hopefully you would get some suggestions and you already know how to pick the best product.

How to Use Knife Sharpeners??

To get the best out of your best home knife sharpener, you must know how to use it properly. Let’s give you some basic idea first.

An electric sharpener normally has 2 or 3 grinding wheels with different coarseness. When honing a knife, you should start with the coarsest one and then move to the finer ones. You’ll get this information from the user manual.

The Steps…..

»  Place the knife into the slot first and push it down as far as possible and stop when it reaches the grinding stone.

»  Don’t forget to start from the hill and pull through to the top

»  It’s time for drawing now. The slot will hold the knife at 15° – 20° angle (approx.) and at the time of pulling through the handle will also angle up a bit.

»   Make 2 passes at least one each side for reshaping. 

»  Repeat this process when moving to the next stage of fine honing

»  Once your blade is sharpened, use the fine-grit stone if any re-honing is required.

  What Is the Best Angle to Sharpen a Knife??

Selecting an angle is probably the easiest as well as the most important stage in sharpening. For most of the knives a 20-degree angle will do just fine unless you are too much concerned about the fine tuning of the bevel angle.

Select a larger angle if you want a durable edge as lower angle provides less durability. The sharper your knife becomes, the more you low down the angle.

The diagram below will give you some idea about choosing the right angle for your electric knife sharpener.

Knife Type Angle
Pocket Knives, Hunting Knives, Sport Knives 25-30°
Fillet Knives, Paring Knives 12-18°
Machete, Cleaver 30-35°
Kitchen Knives, Carving Knives, Chef’s Knives 18-25°

How to Maintain the Sharpener??

Cleaning is required when the performance of the sharpener deteriorates. For a better outcome it is better clean the machine once a year.

The Cleaning Process:

• Some model like Chef’s choice 130 has a specific dressing tool to perform cleaning tasks. You would get the detailed info on how to clean described in the user manual.

• The cleaning process varies from brand to brand. So, we won’t go more details in this topic. Some models support manual cleaning process.

How knives dull??

Dullness occurs due to corrosion. Yet there are many reasons that are responsible for the dullness of the knives. Knives tend to damage if you perform tasks like scraping, opening tin, slicing heavier items or crushing ice.

Sometimes cutting acidic fruits and vegetables causes corrosion in the blade. Even washing the knives with harsh chemicals or keeping it in high temperature may bring drastic effects to your cutlery.

Prevent Measures

•   Avoid heavy wooden cut boards while cutting.

•  Select appropriate knife for any task.

•  Perform fine sharpening to repair bending.

•  Regular maintenance is required.

How Much Pressure Is Required for an Electric Sharpener?

Knowing how to apply appropriate pressure is a prerequisite to operate an electric knife sharpener. The sharpening process is almost same for all kinds of sharpeners.

The rule is to never operate a sharpener from the backside, it should be done equally on each sides.

You only have to exert the amount of pressure that ensures consistent contact of the blade with the abrasive disks.

  • Never Apply Too much Pressure 
Check for The Burr On the Blade

Checking the burr on the blade is equally important. Normally a burr will be present on the right side of the blade if your last pull is on the right slot.

In order to check the burr just place your finger on the flat part of the blade and slowly move towards the sharpened edge.

If there is any burr, you’ll feel a lopsided area on the edge. It is a good indication and you should go for the next stage after getting that.

If you don’t find any burr, then you have to perform a couple of pulls more in the stage and proceed to the next step. Just remember to start from the flat side and move finger down while checking the burr on the blade.

 Electric vs Manual Knife Sharpener
