What to Look For

So…what is the best electric knife sharpener? That all depends on your needs and what you plan to use the sharpener for. Here are some factors to keep in mind to help you figure out what you’re looking for.



Electric knife sharpeners fine-tune the blade of your knife into a fine point by grinding it against an abrasive. This is basically a hard, rough surface, and can be made of everything from ceramic to stone to sandpaper. Professional electric sharpeners might even use diamond or other gemstone abrasives for higher-quality sharpening. 



If you’re at all familiar with the concept of sandpaper, you’ve probably heard the term “grit” before. Grit refers to how coarse or fine the sandpaper is. The finer the grit, the smoother the surface will be once you’ve sanded it. But you can’t start with the finest grit. You have to start at a coarser grit and work your way up to get the smoothest possible surface. 

The same principle applies when it comes to knife sharpening. The best electric knife sharpeners will have multiple different sharpening stages, each with progressively finer abrasives, to take your blade gradually from dull to razor-sharp.


Blade Compatibility

Not all knife sharpeners are created equal. While most machines will easily handle a straight blade, not all are compatible with serrated blades or kitchen scissors, which are the other two most common blades you’ll need to sharpen. Professional-grade machines can even sharpen different tools (kitchen or otherwise). So be sure to think about what you want to sharpen and make sure the sharpener you pick is up to the task.



Most electric sharpeners will only take around a minute to take a knife from dull to sharp, but be sure to double-check. If you’ve got family sitting at the table demanding dinner and a blade that just won’t cut through the pork roast, the last thing you want is to spend twenty minutes getting your knife sharp enough to serve up supper.



Knife sharpeners are, on average, about the size of a 2-slice toaster on its side. Smaller ones are available, of course, and there’s no denying their convenience. But remember that nicer electric sharpeners have more sharpening stages. These machines will have to be bigger and heavier to accommodate more steps. 


Noise Level

Noise isn’t really something you think about when you think about a knife sharpener, but some of the machines out there can get loud. As an electric device, you aren’t going to find any silent options, of course. But check to see what reviewers say about noise level. If you’ve got an anxious dog or a sleeping baby (or even temperamental neighbors), you don’t want your blade maintenance to disturb them.
