Best Sharpening Stones

A knife is only as good as its ability to nimbly slice and dice through ingredients. A sharpening and honing tool is essential to maintain that edge. Electric and manual knife sharpeners are effective, but a whetstone is the gold standard when it comes to fine, razor-sharp blades. Though sometimes mistaken as having to do with water, whetstone comes from the word "whet," which means to sharpen. 

Whetstones come in a variety of materials from oil stone to diamond stone to water stones to ceramic stones. They also have a range of grit levels from coarse at the lower end to fine at the high end. Generally, you want a coarse and fine grit, whether that comes in separate stones or a two-sided option. Whatever choice you make, a whetstone is a solid investment for the best knife care—they allow ultimate control over the angle and refinement of your blade. No more worries about slicing through that ripe tomato when you rely on a whetstone for home sharpening and honing.

After researching, our favorite wet stone is Sharp Pebble's Premium Whetstone Knife Sharpening Stone. For a long-lasting oil stone, we recommend Norton's Combination Oilstone.

Whether you're looking for your first whetstone or are expert enough to handle one with a diamond surface, these are the best sharpening stones for all your knives.

Best Overall, Water Stone

Sharp Pebble Premium Whetstone Knife Sharpening Stone

Sharp Pebble Premium Whetstone Knife Sharpening Stone


What We Love: Sharpening guide included, affordable, double-sided, easy to clean

What We Don't Love: Fine side grit is a little soft, needs to soak in water before use

Water stones use water as a lubricant to enhance sharpening and to carry away residue. This budget-friendly water-stone option from Sharp Pebble has the optimal two-sided grit. The 1,000/6,000 grain allows you to repair and sharpen seriously dull blades and hone edges to a sharp point all in one stone. And the rubber base affixes the stone to a nonslip bamboo outer base for extra stability during the process.

Versatility is another bonus with the Sharp Pebble. You can sharpen everything from chef's knives to garden shears, and the generous 7.25 x 2.25-inch surface allows plenty of area for even larger blades. The included angle guide will give beginners a sense of ease since it helps you find the exact angle effortlessly. This is a water stone, so be prepared to soak it for approximately 15 minutes prior to use and keep a bowl of water nearby to maintain moisture level during processing.

Grit: 1,000/6,000 | Design: Two-side grit with base | Material: Aluminum oxide

Best Overall, Oil Stone

Norton Combination Oilstone



What We Love: Excellent for repair work, durable, no presoak necessary

What We Don't Love: Honing oils can be messy

Oil stones are longer-lasting in comparison to their softer water stone counterparts. The Norton double-sided oil stone is made of aluminum oxide, known to be tough and wear-resistant. With a 100/320 split, this stone is more for repairing and sharpening, so you may want to add a high-grit stone for refining and polishing. 

The Norton Combination Oilstone requires no presoaking, and it is prefilled with oil to keep the surface lubricated during processing. This tough model promises to last a long time, but cleanup can be messy. It's recommended you clean this with kerosene and a stiff brush and let it dry completely before soaking it in mineral oil.

Best Budget

Whetstone Cutlery 400/1000 Dual-Sided Sharpening Stone



What We Love: Durable, no need for honing oil

What We Don't Love: On the smaller side

Though this whetstone comes in at an affordable price, it does not fall short on durability. The silicon carbide construction withstands a lot of use before showing any wear. And the ample 7 x 2.25-inch size ensures you can work even large blades without worry. 

This Whetstone Cutlery sharpening stone is double-sided, offering a coarse 400 grit for repairing damaged knives and a still-coarse 1,000 grit for effective sharpening. The thing this model lacks is the higher, finer-edge polishing ability, but it is a basic stone that will keep your knives useful. Be sure to soak the whetstone in water for 10 minutes prior to use, and for best results, lay it on a wet towel during use to keep it from sliding around and protect your counters. This will also keep the other side of the stone from being marred during use.

DMT 8-Inch DuoSharp Plus Bench Stone

DMT DuoSharp Double-Sided Diamond Whetstone


What We Love: Sharpens fast, uniform sharpening surface, durable

What We Don't Love: Needs a break-in period

The DMT DuoSharp’s monocrystalline structure offers a uniform diamond surface that has been engineered flat to ensure even contact between your blade and the whetstone. The generous 8-inch surface area can accommodate a wide variety of tools—from large chef's knives to kitchen shears—with ease, and the stone can be used dry or wet, offering convenience and versatility. 

This double-sided model has a coarse and fine grit side, but as with all diamond surface whetstones, you must use extreme caution when sharpening and honing. Diamond is a very sharp material, and without the proper attention, it can damage knives. This also means it is a very fast choice if you need a quick touch-up for a razor-sharp edge. The DMT DuoSharp comes with a locking bench base to keep everything in place while sharpening. The diamond surface is highly durable and will last a long time with little need for flattening.

Grit: Dual grit (25 microns and 45 microns) | Design: Two-sided grit with locking base | Material: Diamond-plated stone

What to Look for When Buying a Sharpening Stone


Oil Stones: Oil stones tend to be the traditional whetstone people grew up using. They are durable and require very little flattening because of their hard material. They do require oil to lubricate the metal during processing and can involve messy cleanup. They come in a variety of grits, but their hard surfaces generally require more swipes in the sharpening process. 

Water Stones: Like oil stones, water stones come in natural and synthetic materials. Water stones tend to be softer and require more flattening than other varieties, but this also means faster sharpening and honing, requiring fewer swipes, a clear advantage. Unlike oil stones, water stones are easier to clean up, but they also require initial soaking, as well as constant moisture during sharpening. 

Diamond Stones: The hardest of all surfaces, diamond provides fast results. They come in two varieties: a surface dotted with holes to capture the swarf or metal debris, or a continuous diamond surface that helps with sharpening tools that might catch in the holes. Diamond surfaces are available in two versions, monocrystalline and polycrystalline. Monocrystalline tends to be more durable and lasts longer. Diamond stones tend to be expensive because you know, diamonds, but they also require little if any flattening and last a long time. They're ideal for sharpening ceramic knives.

Ceramic Stones: If lubricating your whetstone is a dealbreaker, ceramic might be the right choice. Most ceramic whetstones require no water or oil to use, so no messy cleanup is required. They are generally very durable and require little resurfacing. And the material they are made from is almost as hard as diamond whetstones, so they will last a long time. The downside is they usually come with a hefty price tag.


Basically, the higher the grit number, the finer the stone. Coarse grits are effective for sharpening or repairing tools, and fine grits are better for refining edges and angles.

When looking at grit numbers, it is important to keep in mind the lower the number (100 to 900), the better it is on rough knife edges, even those with chips. Once you get in the 1,000 to 3,000 grit, you are still going to get effective sharpening but think of a knife that is duller rather than damaged. 

Grits between 4,000 and 8,000 are most effective for honing an already sharp knife—think of this as a polishing grit level rather than sharpening. The higher the grit number, the more control you have over transforming your edges, but that also comes with a hefty price tag.

Diamond stones use microns to indicate how fine or coarse the grit is, but the same rule applies: low number equals coarse, high number equals fine.


Most whetstones will come in either a one-sided or two-sided grit. A one-sided grit can be effective for touch-ups, but often you will need a second grit for polishing and refining. The two-sided grit offers both options in one stone. Usually, it's a coarse, low number grit on one side and a finer, high number grit on the other.

The other consideration in design is whether a stone is secured with a base or handheld. The free-standing or pocket varieties offer portability but make getting a stable angle difficult. The base-secured models offer more precision, but you need a solid surface to set it on for processing.


How do you use a whetstone? 

Depending on the material you purchase, you may have to soak your whetstone before use. Be sure to refer to the manufacturer's label for full instructions. 

Water stones require some contact with water whether that is submerging it before use or just a sprinkling of water on the stone’s surface. With diamond stones, water can be used to prep the surface, but there is also an option called lapping fluid, which will prolong the effectiveness of a diamond surface. An oil stone needs a bit of mineral oil on the surface prior to sharpening—the same used to condition and maintain wooden cutting boards after they've been cleaned.

Whatever material you purchased, here are the basic steps to utilize your whetstone. First, soak your stones and set up your station. If you are using a whetstone that requires water, keep water beside you to ensure you have enough moisture on the stone to complete sharpening/honing.

Starting with the coarse-grit stone or side, hold the blade at a 20-degree angle, securing the heel of the knife to the far edge of the stone. Maintaining even pressure, drag the knife slowly over the stone toward you while keeping it at the 20-degree angle. Finish the stroke and repeat, approximately 10 times.

Switch to a fine-grit stone or side and repeat the process. Then you clean up and test the blade. This can be messy. Try designating a dishtowel you will always use for this task because it will probably stain.

How do you take care of a whetstone?

The answer depends on the stone. Water and diamond surface stones require simple rinsing with hot water, maybe a scrub to remove metal particles, and thorough drying. Oil stones need an application of mineral oil to maintain their surface. You can also use a little hot water and dish soap to remove any debris from your oil stone. Just be sure to dry and rub with oil. 

For tough cleaning jobs, break out the Bar Keeper’s Friend under your sink. Like stainless steel, it can remove hard-to-clean debris from whetstones. Be sure to rinse and dry the stone after.

My personal tip is to keep a little sandpaper on hand to flatten your whetstone. Every time you sharpen and hone—two different but equally important functions—the process creates high and low spots, also known as dishing, on your stone’s surface. To keep the stone level and at optimal performance, take a few swipes with a piece of 400-grit sandpaper. Water and oil stones are most susceptible to dishing.
