Aug 29

If your knife starts showing signs of wear and you know that you should sharpen it soon, then it is time to think about buying a good electric knife sharpener. Never used one before? No worries! In this article, we have put together all of the features that you should look for in a knife sharpener.

Except for the price, warranty and the safety features, there are a few factors that can influence the quality of such a device. Also, you should look for features that will ensure your products’ durability.

What to look for in a good electric sharpener?


A good electric knife sharpener is the device that fulfils all your requirements regarding the edge, the angle, the guidance, safety and abrasiveness. Here are the most important features of the perfect sharpener:

  • Two or more stages – electric knife sharpeners will get the job done impeccably if they have more than one sharpening slot, as they give you more options and are more versatile. For example, if your knife is dull, you need a coarse slot, but if it only needs stropping, then you will need a softer slot with less abrasive materials.
  • Diamond abrasives – the ideal electric knife sharpener has diamond abrasives, which help sharpen the blade in a softer, more effective way.
  • Compatible with ceramic knives – most electric sharpeners are only compatible with metal knives, but lately, manufacturers understood the importance of including ceramic-compatible attachments or slots, given the high demand of such knives. Find a product that has this feature and you will not encounter difficulties with your most sensitive knives.
  • Suitable for serrated knives – not all electric sharpeners are designed to work with serrated knives, as their blades are toothed. Although they are mostly used for bread cutting, they also need sharpening from time to time in order to maintain the quality of the cut.
  • Suitable for scissor and utility knife sharpening – although this might sound strange to you, there are manufacturers that produce knife sharpeners in the power tools category of products. These devices are powerful, highly compatible with anything that has a blade and worth having due to their resistance, sturdy materials and high variety of accessories.
  • Able to convert 20-degree to 15-degree angles – a sharpener’s ability to convert a thicker knife into a thinner one with precision is to be appreciated. Having this feature available, you will save yourself a lot of trouble in the kitchen.
  • Angle guide – if you have different knives in your kitchen and you use them frequently, then you should buy a sharpener that comes with an angle guide. European knives must be sharpened at different angles than Japanese knives, for example, which is why you need to have a wide variety of angle choices available.
  • Adjustability – make sure that the device you buy is highly adjustable. For example, serrated knives need a different abrasive material and shape than regular ones. Also, single bevel blades need abrasives only on one side, which means that the attachment or stage should be different. You should be able to adjust the speed and intensity, too.

When looking for an electric knife sharpener, ensure that you find at least some of these features in the product that you want to buy. If you make the right choice now, you will probably not have to buy another one in the next decade.
