Best Knife Sharpener Reviews 2020

A good knife needs to be sharp. While that might seem like a fairly obvious point, it is an important one nonetheless. Not only is a dull knife relatively useless as a tool, but it can also be dangerous to use. Dull knives require more force to make a cut than a sharp edge knife, and increasing force increases the chances that you could injure yourself along the way. For both the performance of the knife and the safety of the user, knife sharpness is something that should always be considered before making your first cut.

knife needs to be sharpBefore getting too far into this article, it is important to highlight the difference between sharpening a knife and honing a knife. When you sharpen a knife, you are actually removing material from both sides of the knife edge to make it sharper. That is not the same thing as honing, which is simply realigning the blade edge to restore its sharpness when in use. These are two very different actions, and they use different tools to accomplish the job. For instance, if you have a block of kitchen knives in your home, the set probably includes a honing steel. This is a good tool for maintaining your edge, but it is not going to sharpen a knife. To do that, you need an actual knife sharpener of some kind.

After doing all the hard research for you, we’ve put together 7 of the best knife sharpeners in the comparison table below.

Later in this article, you will find a list of seven of the best knife sharpeners on the market today. Prior to that list, we will cover some of the main buying points and concerns that you should weigh before making a purchase as there is a bit of a learning curve. It is our hope that through a combination of information and product options, you will be able to select quickly and easily your next knife sharpener.

Major Buying Considerations for a Knife Sharpener

Before you spend even a dime of your hard earned money on a manual knife sharpener, it is important that you understand what you are looking for, and what kind of product will best suit your needs. There is a wide-range of price points covered in this market, from products that cost just a few dollars to some that cost ten times that amount or more. Nobody likes to waste money, so it is certainly in your best interest to take a little time to do some research. Fortunately, much of that research has already been done for you in this article.

1. Know Your Sharpening Angles

One of the first points to understand about knife sharpeners is that they have to be able to match the sharpening angles of the knives in question. Your knives have been designed with a certain angle between the tip of the blade and the rest of the knife, and that angle needs to be maintained while sharpening. Therefore, it is important that your sharpener matches up properly with the knife to get a good sharp edge.

Fortunately, many sharpeners are designed with the ability to suit some angles. For instance, 15 degrees and 20 degrees are the two most-popular angles for edges on kitchen knives, so many sharpeners are built with those designs in mind. It would be okay to purchase a sharpener that only accommodates one specific edge angle, as long as you make sure that the angle matches up with all the types of knives in your set. Trying to sharpen a blade at the wrong angle could do serious damage to the knife, so that would be an expensive mistake to make.

2. A Gradual Process

Sharpening a knife is a job that requires more than one step in order to be completed successfully. In fact, you may have to go through as many as three stages to wind up with a blade that is perfectly sharp. A high quality knife sharpener will have at least two, if not three different, stages, each with a different amount of grit. A common assembly is a three-stage sharpener system that has a coarse stage, a medium stage, and a fine stage. It might be helpful to think of these stages like sandpaper otherwise known as sharpening stones. As you get finer, you take less material off of the knife so that you can do more delicate work.

When a sharp knife has gone extremely dull, you may need to progress through all three of these stages. You would start with the coarse stage in order to roughly create a new edge that can be used for cutting. Then, you would move up to the next stage to refine that edge, and finally the last stage to finish it off perfectly. The grind would be getting finer as you go, so you would be refining the edge gradually until it is ready for use.

The beauty of having something like a three-stage sharpener is the ability to work a knife all the way back from being extremely dull. However, it is also nice because you can pick and choose the point in the process that you would like to start with. For example, if you have a knife that is only slightly dull, a quick trip to the finest stage of the sharpener might do the trick perfectly. You would be able to avoid taking too much material off of the knife, and you would have the job done in just moments.

3. Safety Always Matters

in a way that could be dangerousYou shouldn’t have to worry too much about this point when you are buying a quality product from a respected company, but it should be addressed nonetheless. Anytime you are sharpening your knives; it’d be a good idea to be very careful and make sure you are using the equipment in the proper way. Never move the knives around in a way that could be dangerous, and keep your fingers (and everything else) clear of the area where the actual sharpening takes place.

The majority of the products on the market have been designed with safety in mind, so they make it pretty easy for you to keep your fingers clear of the sharpener. However, bad decisions can always override good safety design, so it is up to you to operate the sharpener in a safe and responsible manner.

4. Surface Material

As you look through the options for manual knife sharpeners or even sharpening stone, you will notice that there are a number of different materials that can be used actually to do the work of sharpening the knife blade. Some of the options you are likely to run into include tungsten carbide, ceramic, and diamond. As you might expect, the diamond option is the hardest, and it is also typically the most expensive. A good diamond surface can do a tremendous job of sharpening a blade, but you will likely have to pay for the convenience.

In terms of the surface that is offered on each of the sharpeners listed, you will notice that many of them advertise a grit rating, again much like in the world of sandpaper. A lower number equals a rougher surface on this scale. A rating that is around 100 would indicate a rough surface meant to start work on a dull knife while something in the 1000s would be a finer surface for finish work.

Taking the information above into consideration, you should now have a better idea of what you are looking at when you start to browse specific models – such as the seven highlighted below.
