Our recommendation is the Lantana Smart Sharp Knife Sharpener. It comes at an affordable price and it will completely amaze you.

Whether you’re a professional chef working in a busy restaurant, a stay at home mom, or an overworked student, you’re sure to have a favourite life-saving kitchen tool. For some, it’s an incredibly complex device that can cost hundreds of pounds and uses up almost all of their counter space, but for others, it can be as simple as a kitchen knife. Knives are tricky, as few people realise how far a good, high-quality knife can go when it comes to preparing food quickly and with as little hassle as possible. But, whether or not you take the time to test how good your knives really are, there comes a time when your favourite one loses its lustre and becomes dull to the point of becoming unusable. So, what now?

Well, you always have the option of going out and repurchasing the same knife, but what if you hadn’t really realised how dull your favourite one has become until you start preparing a three-course meal for six people that are coming over for dinner on that same day? Also, if you only use the bread knife and the butchery knife, and your favourite brand only sells them in sets, why would you spend all that extra money on something you’re not really going to need? The simplest, and cheapest, option is to just sharpen them! Sharpening your knives can be easy and almost effortless; provided you have the proper equipment. In this article, we’ll be listing various knife sharpeners that provide the best user experience and have an excellent price-to-quality ratio. So, let’s explore and see which ones “made the cut”.

Types of Knife Sharpeners

When a knife is no longer able to cut effectively, it is usually because the blade’s edge has become dull or misaligned through prolonged use. The main thing to consider when looking at sharpeners is the difference between honing and sharpening. If you’ve ever watched a cooking show, you’ve probably seen master chefs using a metal instrument to supposedly “sharpen” their knife. This isn’t a sharpening tool, but instead honing steel. Honing doesn’t actually sharpen the knife; it just realigns it without shaving off too much of the metal.

What we consider sharpening is the process of shaving off and grinding the blade to produce a crisp edge. Depending on your level of experience, your budget, and how much care you want to give to your knives, there are some main options that will suit your needs.

Sharpening Stones

The most traditional way to sharpen a knife is to use a sharpening stone. They are used for sharpening very dull knives by forcing the blade against the stone at different angles to bring grind a new, sharper edge. The beauty of this type of sharpener is that it can also be used on scissors and razors as well as knives.

Although this method can be relatively inexpensive, it takes a while to master the skills necessary to achieve the best results, as you need to hold the knife at very precise angles to make sure the blade stays straight. So, keep in mind that it may require a substantial amount of time before you’re able to get the results you desire. On the other hand, it could develop into an exciting hobby.

Manual Knife Sharpeners

A manual sharpener is the most common and accessible type of household sharpener. They work by dragging the knife through abrasive pads sandwiched together in a V shaped chamber, which shaves down the blade’s edges into a sharp point. It’s incredibly easy to operate and costs far less than any electric knife sharpener. The dragging motion makes it less difficult to apply even pressure on the sharpening pads, making them much easier to use than a sharpening stone, and they are suitable for sharpening knives of almost any size. In addition to the narrow chamber, most manual sharpeners will have a second, wider one, that can be used to sharpen kitchen scissors.

There are both hand-held and stationary models available – if you are short of counter or drawer space, the first one might be the better option, as it is smaller and fits into different cupboards and compartments much more easily. It is important to note that this type of sharpener can’t repair any extensive damage to a blade that’s been through more than its fair share of use, and is, thus, best intended for less severe dullness. In addition to that, not keeping constant downward pressure on the knife while dragging the blade through the V-chambers can, in fact, create unevenness and damage it further.

Electric Knife Sharpeners

This type of sharpener can end up being a significant investment, depending on how many features you want it to have. An electric sharpener works in a similar way to its manual counterpart: two blades create a V formation to allow for more natural use. The only difference is that the abrasive pads on this type of device are motorised, and spin against the knife, thereby taking much of the manual labour out of the equation. As with any electronic device, especially one not as commonly used as, for example, a toaster, it is crucial to adhere to the safety instructions given in the manufacturer’s user manual. After you’ve introduced yourself to the way your particular device operates, you should turn it on and, without pressing down too hard, pull the blade through the slot that fits your blade size.

This way of sharpening a knife has many benefits; there is no need to produce downward force, and they usually have spring-loaded guides that make sure the blade stays in constant contact with the abrasives. This addresses an issue mentioned in the previous example: unintentionally creating bends and cracks by improper sharpener use. The biggest drawback of these machines is the high price point across the board, but, if cooking is something that you do professionally, or you are unable or unwilling to sweat over a manual sharpener, you can see how investing in an electric sharpener |can pay off in the long run. Even though a sharpener like this can set you back, sometimes, hundreds of pounds, there are companies such as Chef’s Choice that make affordable products while offering excellent quality.

Kyocera Battery Driven Diamond Sharpener DS-38

Ah, that relaxing time when you prepare your favourite meal while humming your favourite song, all of a sudden spoiled with a blunt knife. No, it’s not a scene from a horror movie, but it’s kinda like horror when you realize that your knife is far away from sharp, and hence-useless.

Worry not, as nowadays the market offers tons of practical and handy gadgets, among which diamond knife sharpener. Made in the creative workshop of Kyocera, the product is just what you need if you enjoy culinary adventures, and the last thing you want to ruin is a knife that won’t cooperate.

Advantages of Kyocera Battery Driven Diamond Sharpener DS-38
  • Simple to use
    All it takes is to put this gadget on a flat table (or some other similar convenient surface), hold it with one hand (so as not to move), and put the knife into the slot (or groove, as you wish). Then you slide it backward several times, gently and slowly, and voila- the knife is sharp. Even beginners can use it with no problems.
  • Auto adjust
    There’s no home with just one knife only, and none of them has the blade of the same size, shape. Thankfully, the sharpener will adjust to the cutting part, providing perfect blades for both smaller and larger knives.
  • Suitable for ceramic knives as well
    Since the ceramic knifes gradually conquered the market, manufacturers needed to come up with an appropriate sharpener. Back when these knives were just getting popular, the company asked the consumers to send them back to the service department and have it sharpened, but, luckily, they tailored a hassle-free solution- a gadget that can be used at home.
Bottom Line

Coming from a brand that provides both originality and high quality, consumers can be at ease that the product they buy is a reliable one. Great thing is that it works for both metallic and ceramic knives (made by the company), but a disadvantage is that it cannot be used for all types of knives- for example, bread cutting, thick blade, deba, single-edged knife (such as sashimi knife). Also, bear in mind that batteries are not included in the product, and it requires 4 AA batteries (alkaline). And yes, grinding stone cannot be replaced.

Serrated Knife Sharpeners

Your serrated knives can give you a headache when you realise they don’t perform as well as they used to. The serrated edge of this type of knife works similar to that of a saw, so it can still cut when it becomes dull – but just because it is still technically functioning, it doesn’t mean it will be functioning as well as it could.

A dull serrated knife will tear or shred, rather than cut smoothly. The main problem with this type of knife has always been that using regular manual sharpeners just doesn’t do enough to restore the sharpness, as you can’t operate them as fast as you with straight edged blades. There are, however, companies that make sharpeners specially for serrated blades, which resemble a smaller version of honing steel.

The time required to hone a blade with this device is roughly 1 minute for a first-time honing, while re-sharpening takes roughly 10 seconds. That is quite fast, you must agree.

What to Look for in a Good Knife Sharpener

There are a lot of different sharpeners on the market, and even more information available on the best way to use them. In the previous paragraphs, we’ve listed some options we personally believe are the best, budget friendly options. When you look into buying a knife sharpener, keep in mind:

  • Usage Frequency
    Even though sharpening a knife, and thereby re-using it, will save you money in the long run, think about whether you’re actually going to get that much use out of your new device. If you only cook sporadically and have a set of high-quality knives, then maybe you should opt for a simpler, manual sharpener for those quick fixes.
  • Cost
    If you think that an electric sharpener is the best fit for you personally, consider how much money you’ve invested into your knives so far. If you have a set of low-quality knives you wish to sharpen, maybe opting for the most expensive, most intricate sharpener won’t do you as much good as you intend. Also, look at customer reviews, as price doesn’t always ensure quality.
  • Usage
    The main idea here is that, if you regularly have to cut through hard materials, such as bone, then a simple manual sharpener just won’t do the trick, and you should either opt for an electric device, or, if you’re up to the challenge, a sharpening stone. Look at how you use your knives and factor that into your criteria.
  • Effectiveness
    If you’re looking to get things done quickly, and need the sharpest edge your knife can offer, go for the electric sharpener. On the other hand, if you want to have the most control over how your blade gets sharpened, go for the sharpening stone. Finally, if what you require is sharpening your knife effectively and on the go, while keeping your wallet full and your kitchen island clutter-free, get yourself a manual sharpener.
