8 Best Sharpening Stone for Kitchen Knives 2020

A good, sharp kitchen knife is one of the most essential tools in any kitchen. Both professional chefs and home cooks alike cite a reliable sharpening stone and a durable knife as one of the things that can really make or break any meal and cooking experience.

Best Sharpening Stone

Choosing a sharpening stone isn’t something to be taken lightly. If you cook regularly and need your knives to be sharp, choosing a stone that fulfills your personal needs is vital. There are a lot of different stones to choose from! This list will get you started down the right path.

What Makes the Best Sharpening Stone for Kitchen Knives?

1. A Good Stone Type

When you’re trying to find the best sharpening stone for your kitchen knives, it’s important to remember that there are a few different types of stones available. Knowing your personal preferences as well as the care needs of your knives is essential to choosing a good stone.

Here are the main sharpening stone types that you’ll be able to choose from:

  • Diamond stones: If you’re new to the world of sharpening stones, you’ve probably only heard of diamond sharpeners. Diamond whetstones are excellent in certain situations, but in others they may not be as efficient as other types of sharpening stones.Industrial diamonds create a rough sharpening surface that can be used outdoors with or without lubrication. Diamond stones tend to be a bit larger. Therefore, diamond stones are usually best for outdoor tools, and are often not as satisfactory for kitchen knives.
  • Water stones: Water stones are quickly becoming more and more popular, especially in the world of kitchen knives. These stones require a 5-10 minute water soak before each use; in comparison with oil stones, water stones are much cleaner to use.Unfortunately, water stones wear down more easily over time because of their softer nature. So, depending on how often you plan to use your sharpening stone, this may be something necessary to consider.
  • Ceramic stones: The ceramic type whetstone is the most “grab-and-go” stone of them all because it doesn’t require any preparation to use, where water and oil stones need either water or oil, respectively. Ceramic stones can be used just as they are.Ceramic stones are hard and deliver an extremely sharp edge. Because they’re more compact, these stones are great for chefs or home cooks who are working in smaller spaces or who want a fast and efficient tool to use for knife sharpening!
  • Oil stones: Oil stones are the least efficient of the different kinds of whetstones, although they can achieve a sharp, even blade if you have the patience. These stones require oil to lubricate the stone surface and in order to sharpen the blade.This kind of whetstone can be made out of either synthetic or natural materials, with the most common materials being Novaculite or Silicon Carbide. Unfortunately, due to the use of oil these stones can be messy to use, but they produce beautiful results!

2. Appropriate Grit

Appropriate Grit_Best Sharpen Stone

Different sharpening stones have different grit levels. While it may intuitively seem like a higher grit level would always produce better results, the reality is that even finer grit stones can sometimes be the best choice! Different grits have different purposes.

When you’re looking at the grit range of a knife, keep in mind that the higher the number is, the finer the grit. For example, a grit level of higher than 1500 indicates a fine grit, while between 800 and 1500 is a medium grit, and 200-800 is a coarse grit.

Almost always when it comes to kitchen knives, a finer grit is more effective. Choose a grit level of 1000-3000 if you’re looking to sharpen up a dull blade or go for a stone with a grit level of 4000-8000 if you want to simply polish up your favorite knives.

The exception to the rule of choosing a stone with a finer grit is if you want to repair a chipped or otherwise damaged blade. In this case, choosing a whetstone with a coarse or medium grit will be your best bet. Otherwise, go for stones with a finer grit!

3. Slip-Free, Grippy Base

The final most important feature of any good whetstone is that it has a solid base. When you’re sharpening a knife, safety is of course one of the first things to consider! Choosing a sharpening stone that won’t slip and slide around on the countertop makes all the difference.

Besides being an important safety feature, though, a slip-free base on your sharpening stone can also speed up the sharpening process! If you’re not constantly having to think about your sharpening stone moving around, you can get a sharper blade more efficiently.
