The Best Whetstone of 2020 to Keep You on the Razor’s Edge

A sharp knife will save you lots of aggravation in the kitchen. While choosing the best whetstones for your knife is not super complex, it’s not something you think about often, so we had questions. We figured you might have them, too.

Wait, What Is a Whetstone Anyway?

You may also hear these referred to as water stones or sharpening tools. They’re rectangular blocks of stone used to sharpen knives.

Whetstones aren’t only for knives, though. You can also use them for things like scissors or hand scrapers.

They’re often made from materials like aluminum oxide and feature different levels of grit. This refers to how coarse the sharpener is and knowing what level of grit to look for is key.

What Grit Whetstone Should I Get?

Whetstones offer grit ranging from 100 up to 30,000. Yes, you read that correctly. The good news is kitchen knives require only a medium-level grit, so around 500 to 2000.

Most of these kitchen knife sharpeners feature more than one level, the most common being a medium and a high-level grit. This allows you to sharpen your knives to standard on the medium, and go beyond, to razor-sharp, with the high.

What Is the Best Whetstone?

We like a whetstone that has a sturdy base that’s easy to use and offers two grit levels. For these reasons and more, we’ve gone with the Sharp Pebble Premium Whetstone. More on that in the review section.

Is a Whetstone Better?

Let’s have a quick look at how whetstones compare to some other popular sharpening methods.

A sharpening steel is a long skinny rod that’s best used to hone a knife that is already sharp. If you’re looking for a last-minute touch-up, before you carve a big piece of meat, for example, you could use one of these.

The handheld or electric-style sharpeners might be tempting because they’re quick and convenient. However, long term, they can damage knives because of the abrasive grinding methods they use.

Each of the sharpeners above has something to offer. However, we prefer a whetstone for its gentle and controllable application. If used properly, you won’t damage your knives, either.

What Factors Drove Our Ratings?

Aside from the construction, usability and grit, a few other factors played a role in our top choices for whetstones.

Did the whetstone come with an angle guide or not? This tool is excellent for newbies who are learning how to use a sharpening stone. It’s not a must, but it is useful.

FYI: it’s recommended, when sharpening kitchen knives, to hold them at 17 to 20 degrees.

A secondary characteristic was aesthetics. We know it’s not everything, but if our kitchen tools look attractive, we’re more prone to use them. That’s why our top choice has a beautiful bamboo base, which offers stability to boot.

We kind of like the way sharpening knives makes us feel… like we are real chefs. And, while this is fun, more importantly for us is how a sharp knife makes cooking more productive, that in turn makes cooking more relaxing.

The Sharp Pebble Premium is our favorite because it includes an angle guide for support, a solid and attractive base structure, and two main grit levels.
