Best Sharpening Stones

The Spruce Eats / Chloe Jeong

If using your knife for a routine kitchen task—dicing, slicing, and chopping—feels like a battle between the food and your hand, it may be time to treat your most indispensable kitchen tool to some TLC, or in other words, sharpening. A dull knife causes fatigue and often leads to accidents due to how much pressure you are likely to exert when using it.

The best knife is one that is sharp. Although getting your knife professionally sharpened is an option, it requires planning a trip to the store or sending in your knives by mail. A sharpening stone in your own tool kit will allow you to hone and sharpen your knives on a regular basis, with no planning required.

Sharpening stones (also known as whetstones or whetting stones) work through controlled abrasion by removing the metal along the edge of the knife as it moves along the coarse surface of the stone. The type of material of the stone and the coarseness determine how much metal on the knife is removed. Sharpening stones are available as oil stones, water stones, or diamond stones.

To help you select the best sharpening stones to keep your knives “on edge," we tested a variety of options at home and consulted with several knife experts about what to look out for. During our testing and research, we broke down important characteristics like material, grit number, ease of use, and value.

Best Overall

Naniwa Chosera 3,000 Grit Stone With Base

Naniwa Chosera 3,000 Grit Stone With Base


What We Like
  • Cuts fast

  • Comes with a base

  • Splash and go

What We Don't Like
  • Can't be used after it thins down

The Chosera from Naniwa is a hard-wearing, splash-and-go (meaning you don't have to soak, just splash a bit of water) stone that creates an outstanding edge on knives. The stone is bonded with magnesia and has finely graded abrasive particles in a high density resulting in sharp edges on the blades. You do not need to soak the Naniwa Chosera stone in water, although it is recommended to keep some water handy to lubricate the stone as you sharpen.

Designed with “cutting-edge” technology and generously sized at 210 x 70 x 25 millimeters, this stone quickly sharpens any type of steel and will last a long time. The Chosera comes with a base attached, and a cleaning stone is also included in the kit.

Good to Know

The feeling when you use a sharpening stone varies from smooth and creamy to gritty, hard, and scratchy. It has no positive or negative effect on the knife sharpening, however, a distracting noise from the stone can make the sharpening process less enjoyable.

Best Budget

Sharp Pebble Premium Whetstone Knife Sharpening Stone

Sharp Pebble Premium Whetstone Knife Sharpening Stone


What We Like
  • Affordable

  • Includes base and angle guide

  • Great for beginners

What We Don't Like
  • Needs to soak in water before use

The Sharp Pebble is a great budget-conscious option for beginners. This double-sided stone comes with commonly used grits of 1000 and 6000, a base, and an angle guide. You sharpen your knife on the coarse side and hone it on the fine side. The stone fits into the base for a snug fit, and the angle guide helps you practice how to correctly hold the knife while sharpening. This is a water stone that requires soaking in water for at least 10 to 15 minutes before you can use it.

During testing, we noted that the included guide is best used on Western-style, mid-sized knives but may not be helpful for oversized knives. The grit selections are sufficient for home cooks who want to learn how to use a whetstone and who haven’t let their blades get too dull. Different knives took different amounts of time to sharpen, depending on their size, shape, and metal material—but all of them were eventually sharpened to a fine edge.

Best Diamond

DMT 8-Inch DuoSharp Plus Bench Stone

DMT DuoSharp Double-Sided Diamond Whetstone


What We Like
  • Sharpens fast

  • Can be used for hand-held sharpening

  • Stays flat

What We Don't Like
  • Not for beginners

  • Can leave scratches on blades if not used correctly

  • Needs a break-in period before sharpening finer blades

The Duo Sharp is a double-sided (coarse/fine) sharpener with a precision flat surface made from monocrystalline diamond. This super hard and abrasive material quickly restores a dull edge on the coarse side and creates razor-sharp edges on the fine side. The stone can be used dry or wet with water as the lubricant.

A sharpening stone is most effective when it's flat, and the Duo Sharp stays flat and does not become uneven or hollowed for a long time. It also has an area of continuous grit for sharpening edges with fine points and small tools. Sharpening is fast, efficient, and clean.

Shapton 2000 Grit Glass Stone


What We Like
  • Lasts for a long time

  • Splash and go

These stones are designed to work fast and efficiently on all kinds of blades.

Shapton stones are specifically manufactured to keep the sharpening surface consistent and provide a sharpening and polishing effect at the same time. Despite being high-end sharpening stones, the Shapton stones are competitively priced, like this general-purpose, 2000-grit stone.

Best for Everyday Knives

Chefic Whetstone Sharpening Stone

Chefic Whetstone Sharpening Stone


What We Like
  • Easy to store

  • Good for kitchen knives

  • Good value

What We Don't Like
  • Needs multiple passes

  • Very soft

  • Not suitable for all types of knives

The Chefic BearMoo Whetstone Premium 2-in-1 Sharpening Stone features two different grits on the two sides: a 3000-grit side for the initial sharpening and an 8000-grit side for polishing and honing the blade edge. Because of its affordable price and versatility, this sharpening stone is a solid option if you're looking to touch up your everyday kitchen knives on a regular basis. Plus, it's compact and easy to store.

This whetstone is a good option if you want an affordable, all-purpose sharpening stone. The 3000-grit sharpening side works for most knives, especially if you sharpen and maintain them regularly. However, knives featuring a hardened blade, like a powdered steel Japanese knife, will require multiple rounds with this whetstone to get the right amount of burning. While testing, we loved how the stone was easy to clean after we finished sharpening; Just rinse it off under running water and gently rub any markings off the surface of the stone.

Final Verdict

If you're looking for a comprehensive sharpening stone that includes both a base and a cleaning stone, go with the Naniwa Chosera 3,000 Grit Stone.

What to Look for in Sharpening Stones


Grit defines how coarse or fine the sharpening surface is. A blade that is blunt or damaged will require a coarse grit below 1000 to shape and sharpen. A medium grit (1000-4000) will sharpen knives that are not completely dull. A fine grit (4000 and above) will hone the knife and create that sharp edge. Diamond sharpening stones use a mesh or micron to specify how fine or coarse the stone is.


Single-face stones come in just one grit. So, you will need a strop or a honing blade or a fine grit stone to complete the sharpening process. Some stones are made in a double-face design, meaning you get a sharpening side and a finishing side in one stone.


Oil Stones

These are stones that require oil to prepare the stone surface for sharpening. Most oil stones were mined from quarries, like the popular natural Arkansas stones that come from Arkansas.

Natural Water Stones

These stones are mined from quarries, a majority of them originating from Japan. However, they are not as widely available as the synthetic water stones these days.

Synthetic Water Stones

These are stones made primarily from aluminum oxide, and because they can be manufactured with consistent grits, they are the most popular stones available on the market.

Diamond Stones

These stones are made with the sharpening surface created using industrial diamonds. They are usually more expensive than water stones but can provide a superior sharpening surface in some cases.


How do you use a knife sharpening stone?

Most sharpening stones available today are either water stones or diamond stones. Some water stones require them to be submerged in water for a couple of minutes before use, while others can be used simply by sprinkling some water on the surface prior to sharpening. For diamond stones, water can be used to prep the surface, however, it is advisable to use lapping fluid, which increases the lifetime and effectiveness of the diamond stones.

How do you clean a sharpening stone?

Cleaning water and diamond stones is easy and, as regular upkeep, just rinsing them under hot running water and using a brush to scrub them keeps them fairly clean. However, it is important to let the stones dry out before storage as prolonged water in the stones makes them soft and they will start wearing out faster. If the stones require a deeper cleanup, keep it simple and scrub with Bar Keeper’s Friend, rinse, and dry the stones.

How long do sharpening stones last?

Most stones will require some leveling after five to seven uses. However, for normal household use, a sharpening stone should easily last 5-10 years. But a lot depends on the material of the stone, as well as the type and number of blades that are sharpened.

“Diamond stones can be good in the beginning, but they lose their effectiveness rather quickly if you use them often," Elan says reflecting upon his decades of experience sharpening knives for professional establishments.
