Things to Consider Before Buying an Electric Knife Sharpener

There are a couple of consideration you will want to make before purchasing an electric knife sharpener.

Type

The first thing you’ll want to check is that your sharpened is suitable for your kitchen knives. There are many sharpeners that will do your kitchen knives and much more, but you want to make sure it allows for the basics before anything else. 

Angle

Typically, 15 to 20 degree angles are ideal for those razor-sharp thin edges you want your knives to have. 

Base

Having a non-slip base is essentially to make sure you stay safe and your knives don’t get ruined. Ensuring that your appliance won’t move while running will allow for the perfect angle while sharpening and make it so you don’t have to hold the appliance manually. 

Overload Protection

This is a feature you will want to make sure you have so that your appliance doesn’t apply too much pressure to your knives and affect the blade shape or over sharpen them. 

Grinding (Stone/Wheels)

The stone or wheels used to grind your knife’s blade will severely affect the outcome of them. For optimal grinding, you may want to opt for all things diamond including the grinding stone, coated wheels, and abrasive plates for polished edges that are razor-sharp.

Tips For Using an Electric Knife Sharpener

Before doing anything else, make sure you read the instruction manual of your knife sharpener. Most will have a two-stage process, but always follow the directions where you can. 

  • First, you’ll need to put your knife in the first slot. If your sharpener requires you  to hold the knife, you will be pushing on the heel as far as you can so that it connects with the grinding stone. Most sharpeners already are pre-set to the angel you need so you likely won;t need to worry about this. 
  • You’ll want to sharpen both sides twice, slowly. 
  • You’ll do this process again on the finer stones but should take you less than a minute. 
  • After you’re done sharpening, be sure to wash and pat your knife dry to get rid of metal shavings. 
  • Finally, make sure you clean where you worked. Some sharpeners will have compartments to catch your metal shavings, but others will not.
