Things to Consider Before Purchasing a Knife Sharpener

With are numerous kinds of knife sharpeners available in the market. It can be quite a daunting task to pick just the appropriate model that could fit into to your kitchen. We have made the task easier for you by breaking down the entire process of knife sharpener selection.

Sharpening knives is the first thing taught in a culinary school. It is more of an art rather than just a task of sharpening knife for your kitchen needs. It is vital to be aware of the basics required for knife sharpening depending on the kind of knife being used by you. A dull knife can after all spoil the entire experience.

With tons of sharpeners available in the market offering different features, it will take some time to understand which one would be the best for your kitchen. This buying guide will help you pick just the right sharpener for you. The first and foremost thing that you need to understand is identify the kind of knives you have in your kitchen. Almost all sharpeners can deal with straight edge blades but not all can be used for sharpening serrated knives.

As not all sharpeners can be used for sharpening Asian-style knives, scissors and sports knives, you need to look for specific sharpeners that are best for them. Another aspect to consider while purchasing sharpeners is how good you are at managing tools and equipment.

Electric sharpeners get your job done faster when compared to manual sharpeners. These are also easier to use. You may need some time to master using a manual sharpener. For instance, there are users who love water stone sharpeners for the beautifully polished edges they offer. However, using these requires plenty of practice and a steady hand.   

You cannot ignore the space that you can spare for saving your knife sharpener. Most manual sharpeners can fit easily in kitchen drawers. Electric sharpeners on the other hand consume a lot of space on your kitchen counter. These are usually as big as a regular toaster. 

If budget is your major constraint, then you can rely on manual sharpeners as these are cheaper than electric ones. Manual ones cost less as they do not have any moving parts and also tend to last longer. If even the slightest noise bothers you, then you will have to rethink about opting for electric sharpeners. These tend to be noisy because of the motor and the scraping sound of the blade against the stone.

If you are left-handed, then you need to understand that most manual sharpeners can be used either left or right handed. There are specific sharpeners suitable for right handers only. If you value your knives, then you must opt for a sharpener that is gentle on the metal and does not generate a lot of heat. Over-grind sharpeners can reduce the life of a blade considerably.  

Grit is yet another aspect that cannot be overlooked while on a hunt for a perfect knife sharpener. Regardless of the kind, all knife sharpeners possess some or the other kind of grit level. Electric and manual sharpeners come with at least two settings. The level of grit is dependent on the amount of metal being taken off the knife during sharpening.   

A coarse grit is best suited for use on a damaged knife that has chips or nicks. Medium grit is ideal for sharpening dull knives but without any damage. Fine grit sharpener helps in refining the edge of your knife. 

Inexperienced users can have a hard time in holding the blade at the right angle during the sharpening process. It may take a bit of practice to master the process. The best angle sharpeners accommodate multiple blade angles between 15 and 20 degrees which are the two most common angles for sharpening kitchen knives. 

Time factor can certainly not be ignored when it comes to purchasing a perfect knife sharpener for your kitchen. Almost all knife sharpeners would accomplish your task, but the pace at which each one would work would be different. There are some sharpeners that accomplish task quickly in comparison to others. 

If spending minutes or over for sharpening a knife does not make any sense to you, then you must opt for a sharpener that requires just a couple of passes.


Knife sharpeners can be categorized based on several aspects such as good performance, the kind of abrasive surface, adjustable angle guide, the number of sharpening stages and a lot more. You can go through our in-depth reviews for identifying the parameters that you should stress on while purchasing a knife sharpener.

The most important feature of a sharpener is its capacity to produce a smooth edge without any scratches or nicks. Surface is yet another aspect that makes a purchase a great one. As we have noticed that almost all sharpeners have diamond as the sharpening material. Tungsten carbide and polished ceramic come second.  

You should always go for knife sharpeners that promise multiple sharpening stages and adequate safety features. A coarse abrasive generally helps in reshaping the edges of damaged or dull knives. Finer abrasives on the other hand are great for polishing and touch ups. Opting for a knife sharpener offering both features can help you going for two different sharpeners. 

Manual sharpeners put a physical barrier between the knife blade and your fingers. Hence these are preferred by most of the users. Electric sharpeners on the other hand use slots for guiding the knife into the sharpening belts or discs.

It is entirely up to you to decide which knife sharpener would be the best fit for your kitchen. With numerous features in the offing and several factors to be considered based on your requirements, it can consume a lot of time in choosing a knife sharpener.

You should study the basics in details before making any move as this will help you take the right decision which you would not have to repent later on. Also look for a decent warranty and good customer service if you are purchasing an electric sharpener. It can come in handy any time in case something goes wrong.

No matter what the case is, you must analyze your requirements in order to understand which electric sharpener would make a best fit in your kitchen.
