Full Guide to Choosing the Best Knife Sharpener 2019

I’m not the chef of our family. That’s more my husband’s thing. He’s pretty handy in the kitchen and likes things fresh and healthy, which makes having the right tools important. Like knives.

He prefers to chop fresh things up rather than frozen and ready to cook equivalents, so our knives get a fair workout -particularly after we bought a slow cooker. A good knife sharpener is, therefore, an essential item – it keeps the blade straight and thin, perfect for fine cutting. It doesn’t take too long to use either – done regularly it doesn’t take more than a minute.

On the safety side of things, a blunt knife requires more pressure to be placed on it, in order for the knife to be able to cut properly. This increases the chance of a slip, and a resulting injury.

The best knife sharpener on the market ensures that your knives stay super sharp and in the best condition possible, without too much fuss or stress.

How is a knife sharpened?

Back in the day, knives were simply sharpened against another knife, but this didn’t do the job as well as today’s sharpening tools. Basically, in order to make a knife sharp, it needs to be rubbed against an abrasive surface several times over, but this has to be done at the correct part, and at the right speed.

Something called a ‘burr’ also needs to be formed on the blade, which is then removed with a different abrasive. This ensures that the knife is not only sharp but evenly so across its entire blade. The best knife sharpener in the world combines all of these factors.

Confused? Don’t be. The best electric knife sharpener on the market will be able to do this for you within a matter of seconds, and the best sharpening stone, e.g. an abrasive surface that does the trick, will also be super efficient. We’re going to talk through some knife sharpener reviews a little later on, to help you make your choice.

Sharpening Stones 

Finally, we have sharpening stones, which are a version of a manual sharpener, but instead of being a metal or plastic tool with grooves provided to insert the knife into, a sharpening stone is literally that, a flat stone. This means it doesn’t have a guide or grooves. This can be an issue for those who are a little nervous about sharpening knives or those who aren’t very experienced.

The best sharpening stone for kitchen knives is made of one of three materials, namely Novaculite, Aluminum oxide, or Silicon Carbide. These stones are abrasive, flat stones which work by first grinding against the steel of the blade, to rid it of any bluntness, and then honing, which creates the final sharpness. This type of sharpener could also be described as the best pocket knife sharpener, because of its compact and small size.

You can see how to use a sharpening stone here.


  • Easily available and quite low cost
  • Easy to use
  • Very effective at sharpening up regular knives, especially small-sized knives


  • There are no grooves or guides, so it can be difficult for a nervous user, or a first time user
  • Takes some manual elbow grease to use!
  • Not ideal for large knives

Of course, it might be that you are not sharpening up a regular kitchen knife, and instead, you could be looking for the best option for sharpening a hunting knife. If this is the case then you need to opt the best hunting knife sharpener for your needs, as opposed to a regular option.

Hunting knives are made of slightly different materials and are shaped slightly differently, due to their specialised requirements. For this reason, you need a specialised sharpener to do the job effectively. Check out the best knife sharpener reviews online to find the ideal option for your personalised requirements.


As you would expect, an electric knife sharpener is a more expensive option than a regular, manual sharpener.

The most traditional type of sharpening stone is made of Novaculite, and this will be the more pricey option in the sharpening stone sub-category.

If you are a commercial user, or you do a lot of cooking and food prep, then perhaps an electric option is the best kitchen knife sharpener for you.

This particular option is a manual type of sharpener, which makes it ideal for those who aren’t so au fait with sharpening knives. The product is sturdy and easy to use, as well as coming from a big name brand, for extra confidence.

New Wusthof Trident Precision Edge, Two Stage Knife Sharpener Review

This is another manual type of knife sharpener, which is a two-stage deal. This particular product works on knives with a straight edge, and it also works on scissors, making it a good household investment. There are two coarseness options, one which sharpens up blunt blades, and the other which is made of ceramic and works to hone the blade and finish up the edges.

Again, you shouldn’t put this manual sharpener in a bowl or water or a dishwasher, and it should simply be cleaned with a slightly damp cloth. This particular sharpener is a little larger than the previous manual type we reviewed, and this is mainly down to the size of the handle, which is an added safety feature.
