Buying Guide of Best Knife Sharpener

There are actually several types of knife sharpeners. You can use whetstones, which are gritty stones that use water or oil to activate the sharpening surface. A whetstone sharpens the existing edge of the knife rather than carve out a new edge. You’ll need to know how to hold the knife at the right angle, and you need patience for this method too.

If you want something faster you can go with the manual or electric sharpeners with the V-notches to carve a new edge on your knife. The correct angle is already set, and you only need a few passes through the sharpener to get a keen edge.

For some people, a honing rod or steel is also important. It’s a long steel rod that’s often coated with a ceramic finish. You pass your knife on the side of the rod to turn a bent blade straight, without having to chip away at the metal. You can use this every day, and they can definitely help your expensive knives in between sharpening sessions. To make your choice, you need to consider the following factors:


If you’re in a hurry, then an electric sharpener is better for you than a whetstone. You only need a few quick passes with the sharpener to end up with a sharp knife. With a whetstone, you may need at least 5 minutes per knife. If you have a lot of knives to sharpen, a whetstone can take a really long time.

Ease of Use

Beginners can make use of manual or electric sharpeners much more easily. With a whetstone, you have to practice a lot to make sure you don’t end up with an uneven edge. Even small sharpeners can cause this problem especially when there’s no cutting slot.

Some sharpeners may even be dangerous to work with. These include sharpeners that require you to sharpen your knife by cutting towards your fingers or palm.

Grit Quality

You need a coarse grit (or a grit level of less than 1000) if you’ll use the sharpener on a knife with nicks and chips. Go with a medium grit (1000 to 3000) if you’re sharpening dull knives that aren’t damaged. Fine grit (4000 to 8000) is fine for refining the knife edge, and this is often what you get with the honing steel.


The size of the sharpener affects your ability to store it properly. If you have a cramped kitchen, then you may not have the storage space for a large electric sharpener. Manual sharpeners and whetstones, on the other hand, can be small enough to fit inside a drawer.

Brand and Product Quality

Some brands are renowned for the quality of their sharpeners, as you can rely on them to work well for a long time. On the other hand, some low quality knife sharpeners don’t last long, and some may even damage your blades.


Prices of knife sharpeners can go from as low as $10 to as high as $150 or even more. You should try to get the best knife sharpener you can afford, especially if you wish to use it every week or even every month. If you tend to use a knife sharpener only when you’re preparing your Thanksgiving feasts, then perhaps you don’t really need a premium model.

Just remember that price is often associated with quality in the knife sharpener industry. Low-quality sharpeners are cheap, while the better ones can get quite pricey.


Our list gives you a wide range of options, with different types and prices to suit your needs and preferences. Pick any of our recommendations, and you’ll likely get a better knife sharpener for the price than any other brand you may pick blindly.

Just remember that if you have knives, you also absolutely need knife sharpeners. Investing on a good knife sharpener makes sense, compared to buying a new knife every time your old one gets dull!
