If you EDC a knife, you know how important it is to keep it sharp. A dull knife will make it hard to cut through rough material. And if it worsens, you can injure yourself when the dull blade slips instead of slices. Buying a quality knife made of good steel means the cutting edge will have optimum sharpness out of the box, but eventually, all blades get dull. Even costly grail knives made of super premium steel must be sharpened after a while.
One of the best ways to handle that is with a set of whetstones, also known as sharpening stones. These are flat sheets of abrasive material that you can slide and rub a knife edge against to rebuild and refine its sharpness. Whetstones made of literal stones and rocks were some of the first and most essential tools used to keep sharp implements going, and they still have a place in EDC today.
Modern whetstones, however, now feature precise amounts of abrasion, defined as grit, based on the smoothness and roughness of the stone. Synthetic options exist, too. For example, the best knife sharpeners are made of ceramic or metal alloys and sharpening stones that feature ultra-hard diamond surfaces.
This guide will introduce you to our favorite sharpening stones and explain why these top picks will help you keep your everyday carry knives in tip-top shape.

What is a Knife Sharpening Stone?
A knife sharpening stone is a flat but abrasive surface used to sharpen and refine a knife’s edge. EDC knives get used often, just like kitchen knives, and that’s where a knife sharpening stone comes in handy. All you need to do is side the entire length of the blade across the whetstone at the same angle as the original edge. This takes away material and hones a minute amount of steel in the blade, recreating a sharp edge like the knife did when it was brand new from the factory.
Oil Stones
Oil is used with some kinds of sharpening stones to help prevent excessive wear. This also makes using the blade on the stone easier without catching on the rough material. Oil stones tend to be cheap, but there are better options for high-end knives, and the available grits are limited because they tend to be made of silicon carbide or aluminum oxide.
Diamond Sharpening Stones
Diamonds are extremely hard, which means a sharpening stone made of diamonds, even a thin and tiny layer, makes short work of the softer stainless steel on blades. Using a diamond sharpening stone can lead to less time spent in front of a stone because it gets the job done quicker, giving you a fine edge. Diamond stones tend to be substantially more expensive than other sharpening stones, so keep that in mind, especially if this is your first time using them.
Water Stones
Water stones are the most traditional form of whetstones, ranging from literal stones taken from quarries that have been worked into a desirable flat shape for sharpening knives to synthetic stones that do the same thing. The difference is that these sharpening stones need to be soaked in water and kept wet to keep them going instead of oil.
Arkansas Stones
As their name implies, these are natural stones from a specific mountain range in Arkansas in the United States. These stones feature sharp pebble premium whetstone silicon quartz material, making them great for sharpening knives. Their grits can be determined based on the color and their feel in hand. Arkansas stones can be more fragile and brittle compared to diamonds and synthetic sharpening stones, and sometimes similar stones that are not Arkansas stones are labeled as such online. But if you get the real deal, you have a tried and tested sharpening stone that you can rely on.
What To Look For in a Knife Sharpening Stone?
A good sharpening stone has the following features:
The right amount of grit to either repair, resharpen, or hone your knife to a mirror polish. Lower grit means it’s a coarse stone, and higher numbers indicate it is finer grit.A non-slip base like a bamboo base or a rubberized bottom that prevents the stone from moving during use and which is easy to clean up.Sufficient length for the knife blades you’re trying to sharpen. If you have a tiny stone, you can still sharpen large knives, but it will take more time and be more challenging than using a correctly sized whetstone for the task at hand.The material you want to use as it dictates whether you have to soak the stone in water or oil (or keep it dry). Different kinds of sharpening stone materials must be maintained in their own way, like with a flattening stone.
Who Needs a Knife Sharpener?
Everyone who carries or uses a knife eventually needs a sharpener, as all blades eventually get dull, even if they are high-end pricey grail knives made of super-premium stainless steel. Even if you’re just a home cook with a high-quality Japanese knife set, having a good sharpening process will give you a razor-sharp edge every time.
