But don’t worry – it’s not quite as difficult as it seems. The secret is finding a knife sharpener that best suits your needs. In this article, we review the best knife sharpener in the UK so that you don’t have to buy new knives every time yours become dull.

What to Look For in a Knife Sharpener

Manual sharpeners, electric sharpeners, and whetstones all have their own set of benefits and drawbacks. But it’s just a matter of figuring out what you need and then choosing which option is better for you. There are some essential factors you must consider to help narrow down your choices.


Whether you are looking for the best electric knife sharpener in the UK or something more manual, you should consider if you have time to learn a technique before buying anything. Using a whetstone may require some practice before being able to sharpen your knives to a high quality. In comparison, electric sharpeners or those with designated ‘slots’ are a lot easier to use and gain great results.


Most knife sharpeners have a multipurpose function. However, some were designed for use on specific types of knives. Many are not suitable for serrated knives or may be recommended for blades of a certain length.

If you have a double-sided knife, you’ll want to buy a sharpener that can work with both edges of the knife at once. There’s no need to buy a double-sided knife sharpener if your knife has only one sharp side.

As a general rule of thumb, refrain from using pull-through knife sharpeners for Japanese knives or those with brittle blades like ceramic. Instead, use a whetstone sharpener since they are suitable for both Japanese and Western-style blades. Using other sharpeners can damage the knife edges.

It would be best if you also consider the bluntness of the knives you want to sharpen and the frequency of usage before purchasing a knife sharpener.


The material used in the production of knife sharpeners will help distinguish it from the rest of the pack. Diamond is the hardest and most durable material, and sharpeners with diamond cutting edges are known to be of superior quality.


storing a kitchen accessoryWhile the size of a sharpener has no bearing on its sharpening efficiency, it is a vital factor to consider when purchasing one. It’s better to buy a sharpener that is efficient enough to sharpen your blunt knives and, at the same time, can fit in your kitchen cabinet conveniently.

Generally, manual and stone knife sharpeners don’t take up a lot of room to store. They are portable and only use up a small portion of your kitchen cabinet. Whetstones with small sizes are also easier to move around than bench stones. However, it is difficult to maintain a consistent angle and pressure when sharpening large blades on them.

Try to get an estimate of how much space you can spare when choosing your knife sharpener. You could also read the description to determine its dimension before making the purchase.
