Knife Sharpener Buying Guide

Types Of Knife Sharpeners

If you care enough about your knives to want to sharpen them rather than throwing them away, you probably have quite a few, of different styles. 

The best sharpener for you would be one that can work with a lot more than the traditional full blade knives. Whether it’s a manual or an electric knife sharpener, ideally, it should be able to also sharpen serrated blades, if not Japanese knives, too. 

Manual Knife Sharpener

A manual knife sharpener requires that you slide the blade between the sharpening stones. It is usually designed as a pull-through 1- or 2-step sharpener. 

It has a more compact design. Sliding the blade up to 20 times, with the same pressure as the one you apply when cutting bread, is usually all it takes to make the best of a manual knife sharpener. 

Electric Knife Sharpener

An electric knife sharpener will automatically rotate the sharpening stones, so you don’t have to slide the blade multiple times through it. You just insert it in the sharpening slot and wait for the moving stones to do their work. 

These models are bulkier, with 2- or 3-step sharpening designs. They also come with a higher price tag.

Having said that, there are electric carving knives too.

Knife Sharpening Kit

A knife sharpening kit consists of several sharpening stones for finer or coarser sharpening. A clamp for securing the blade in place while you sharpen it, with a specially formulated honing oil, is also included with the fancier kits. 

It usually comes packed in its own carrying case, where it holds all the components of the kit, along with the user instructions. 

Such kits come in many different versions, with a more limited or more generous selection of sharpening stones. A good quality kit would have to provide stones with highly polished edges and versatile enough to allow fine and coarse sharpening with both ceramic and diamond surfaces.

Knife Sharpening System

A knife sharpening system is a superior choice compared to a simple kit. That’s because it comes with a more solid base where you attach the knife or the sharpening stones, sticks or a combination of these. 

The base can be clamped on the work surface, for safe operation. With the system usually supporting extensions – other stones you can purchase separately. 

The greatest advantage of a system is, by far, the fact that it allows you to sharpen under a constant angle! 

With a knife sharpening kit, your hand must feel how to position the blade and do it repeatedly, to obtain the finest results. But with a knife sharpening system where you have the stone secured in place and fixed angle guides, everything is much easier and accurate.


The material of which a sharpening tool is made of will have a great impact on the results you’re getting from it. By far the two most common options currently on the market are the ceramic and the diamond knife sharpeners. Here’s what sets them apart: 

Ceramic Knife Sharpener

A ceramic knife sharpener gives you a fast, easy way to do the work. It keeps your knives finely sharpened; it is easy to use, and it is durable. If you make a habit of honing your knives with it, you’ll notice it all becomes effortless. 

Diamond Knife Sharpener

A diamond knife sharpener comes with a diamond layer on top of the grinding wheel. Rather than using it for fine sharpening, like you do with the ceramic ones, it is best for regrinding knives. That’s because it gives a less refined blade. Its sharpening quality can decrease, in time, as the diamond grains start crumbling off.


The level of grit is given by the amount of metal removed from the blade during the sharpening process. From this perspective, a knife sharpener may come equipped with a stone labelled as coarse grit, medium grit, or fine grit. 

A minimum of two types of stones is standard with the best sharpeners on the market. 

The manufacturer will recommend you to start with the coarse sharpening stone for the sharpening, and to end with the smoothest stone to hone the steel, as the final stage. Honing will basically allow you to refine the edge of the blade.

Frequently Asked Questions

Q: How to use a knife sharpener?

Depending on what type of knife sharpener you have, you might be required to pull the blade through the sharpener yourself, or keep it in one place and let the sharpener work on it. The pull-through, manual knife sharpeners are the most common and they have the advantage that they come with the stones already set at the right angle. 

Given the construction of the sharpener that forces you to fit the knife blade into a very thin slot, you can be sure you’ll be getting a good result without worrying too much about the inclination of the blade while you sharpen it. Suffices to pull the knife through the sharpening slot for as many times as the manufacturer recommends, with low pressure, and that’s it.

Q: What is the best knife sharpener?

There are quite a few knife sharpeners you can buy online and that can make an excellent choice. If you want a simple, no fuss model, AnySharp has a more than decent model that we’ve reviewed in this guide. 

If you’re interested in a sharpener that works well and looks just the same, consider the Robert Welch range of products – the famous designer has a special Signature line of knives and a multiple-award knife sharpener that will perfectly pair with those. For the top-of-the-range best knife sharpener, Brod & Taylor can wow you with their best professional knife sharpener.

Q: Can you sharpen ceramic knives?

They say ceramic knives are almost impossible to sharpen, and there’s a reason for it! Ceramic is a really tough material and a diamond sharpener is the only option that could stand a chance in front of it. 

The problem is, however, that even with a sturdy diamond sharpener you’ll have a hard time getting an even blade. To make things even more complicated, ceramic is also brittle, which means if you apply too much pressure on it laterally, it will snap almost in an instant. 

This doesn’t mean you cannot sharpen ceramic knives. It only means it is more difficult and it usually requires perfecting your technique to apply just the right pressure. A good quality diamond stone will be the best choice, followed by a traditional waterstone, as the second-best choice, if diamond ones are outside of your budget.

Our Verdict

From the many options available for sharpening knives, the manual pull-through knife sharpeners are the best choice for those who are just starting out. Sure, you could take your skills to a whole new level by developing an expert technique while using sharpening stones. But that will take a lot of practice.

If all you want is to make your knives sharp again without too much effort, without worrying about angles or abrasive levels, pick one of the best knife sharpeners we’ve reviewed above. They’re simple, practical, perfectly functional and more than accessible. What else could you wish for?
