Best Knife Sharpener

Knives as you know, are home essentials that you just can’t do without. You dice and cut onions, cheese, carrots, cabbage, and literally anything you desire in another in shape. Even though knives can be very harmful when used wrongly, that you can personally do without them is impossible at this time. In fact, other than your own kitchen, a few people include them in their toolbox for minor jobs like unscrewing and scraping.

Nevertheless, despite their usefulness and efficiency, those 2 qualities only last for a while since knives do eventually get blunt. This is why a knife sharpener is another essential. Knife sharpeners are tools that sharpen your knife blade and so avoid a lot of stress when you’re cutting. As a matter of fact, using a blunt knife can lead to injuries since you may occasionally get annoyed and will want to speed up the whole process. That’s certainly not a good move, seeing as you can avoid it with a quality knife sharpener. Though, on the part of the sharpener, factors like the type of knife, affordability, and effectiveness are some of the things to consider.

Knife Sharpener Buying Guide

When it comes to purchasing a knife sharpener for yourself, there are certain factors that matter a lot. These factors help you determine the best knife sharpener to buy. Go through the list that has been created below to note all the factors that need to be considered;


Safety First

Knives are very sharp objects and you must be very careful when handling them, sharpeners can also harm you if you don’t handle them safely. That is why you should make sure that the knife sharpener you are buying, whether, manual or automatic, has an ideal safety feature. For manual sharpener, the sharpening system should be quite distant from the handle. And for electric sharpeners, there should be slot and rail guides to help direct the hand into the sharpening disks. If the sharpener is not safe, it’s better to not have it than to risk getting hurt while sharpening your knife.


Note: There are other safety features that are unique to products.


Hard and Abrasive Surface

The best kind of surface that your sharpener can come with is a diamond surface. This is because diamonds are abrasive and hard. You can also purchase the one made with tungsten carbide and polished ceramic. Anything apart from this might not give you a good result. Abrasiveness is generally measured with the use of grit size and the higher the grit number the finer the abrasive. Check out all these details before you buy a knife sharpener.


Knife Type

Is your knife straight or serrated? This one of the question that you need to ask yourself when you want to buy a knife sharpener. A lot of knife sharpener can only be used for straight knife edges and some others can be used for serrated knife edges. But there some that can be used for both, you should consider buying the one that can be used for both, this will make you avoid the stress and cost of buying more than one sharpener.


Angle Guide

You can set your angle guide and leave the sharpener to do the rest of the job. But for some sharpeners, you might need to be a bit knowledgeable on how to handle it before you can use it. So make sure that you choose a knife sharpener that makes it easy to at least place the knife at the correct angle when sharpening. This will make the operation easier and the blade will be much sharper.



This is one important factor that you must consider when you want to buy a knife sharpener. The price of the appliance must agree with your budget. It shouldn’t be too expensive and you also must avoid buying substandard products because you’re on a budget. So look for something that is moderately priced and will still sing of quality.
