    To maintain the edge and shine of your knives it's important to invest in a good sharpening stone or whetstone. Using a stone to sharpen or hone your cutlery may be a bit more labor intensive, but you'll have greater control over the finished product. If you're ready to give whetstones a try, there are several different types to choose from—the most common stones are oil stones, water stones, ceramic stones, and diamond stones—so it's important that you do your research to find the best option for your needs.

    If you're looking for a versatile sharpening stone that can be used on all different types of knives, we love Sharp Pebble’s Premium Whetstone Knife Sharpening Stone. This kit includes a double-sided sharpening stone with two different levels of grit (1000 and 6000), allowing you to hone dull knives or refine sharper ones by simply flipping it over. It also comes with a bamboo base so it won't slide around when you use it, along with a sharpening guide to help beginners learn the ins-and-outs of their new tool. Made of Aluminum Oxide, it can be used to sharpen not only kitchen knives and chef's knives, but hunting knives, scissors, kitchen shears, and even axes. It measures 7.2 x 2.2 x 1 inches.

    Customers say the Sharp Pebble Premium Whetstone is the perfect tool for beginners and experts alike, writing that it’s extremely well-made, with a sturdy base and effective grit (the double-sided construction is a great feature). The stone should be soaked in water before use, and some owners suggest keeping some extra water nearby to keep it wet while sharpening.

    Best Japanese: SUNER POWER KSS01 Professional Dual 1000/6000 Japanese Grit Whetstone-Knife Sharpening Stone

    Like other sharpening stones, Japanese whetstones come in both synthetic and natural varieties, but both tend to be slightly softer than other sharpening stones. While this means that they don't last quite as long, the fine particles created during use ensure an extra-sharp blade every time. This SUNER POWER stone has two-sided grit (1000 and 6000) and a non-slip bamboo base that can be used on everything from kitchen knives to razors and chisels. Unlike other sharpening stones on the market, it can even be used on serrated blades. It should be soaked in water before use, and it measures 25.1 x 11.7 x 10.2 inches.

    Reviewers praise this stone for exceeding their expectations and honing blades to a razor sharp edge. This whetstone even convinced some buyers to throw out their old sharpening tools—it's that good! Plus, having a razor sharp knife is actually safer in the kitchen and can help improve knife skills. As with most Japanese stones, the materials are on the softer side so the cutting will be much faster.

    Japanese knives are among the best in the world, and their precision and sharpness can be attributed to the beveled blade. If you're interested in adding this tool to your arsenal as well, read through our reviews of the best Japanese knives.

    Best Natural Stone: Masuta Natural "Ocean Blue" Sharpening Honing Stone

    For the most dedicated owners, natural stones provide an unparalleled finish—and the Masuta Natural “Ocean Blue” Sharpening Stone is the best of the best. It comes at a higher price point than synthetic stones because it’s quarried from a now-closed underwater mine off the coast of mainland Japan. The material is of medium hardness and extremely dense, giving the stone a longer life and ultra-consistent sharpening. The stone measures 8 x 2.7 x 1 inch (although it can be purchased in several larger sizes), and should be sprayed with water rather than pre-soaked.

    “Happiness is just a few strokes away,” one customer writes of the Masuta Natural "Ocean Blue" Sharpening Honing Stone. Since its grit is 1200, it’s more of a finishing stone for people who routinely maintain their knives and want to ensure they keep that razor sharp edge.

    Best Ceramic Stone: Spyderco Bench Stone Sharpener with Storage Case

    While most sharpening stones require water or oil to be effective, ceramic ones don't require a cutting liquid, saving users an extra step while still offering quality sharpening. The Spyderco Bench Stone Sharpener is a ceramic stone with medium grit, making it useful for restoring dull or old knives to their former sharpness. It’s wide and flat, measuring 2 x 8 x 0.5 inches so it can be used with larger items like woodworking tools and even skis. It also includes a polymer case with non-skid feet so it won’t slide around on a tabletop or workbench. Since it doesn’t require any lubricant it’s lower maintenance than your standard sharpening stone, and can be quickly cleaned in a dishwasher. "These stones are great and worth the money if you sharpen your own knives," enthused one reviewer. "They're heirloom quality."

    Best Oil Stone: Norton Fine/Coarse India Combination Oilstone

    In contrast with water stones (which, true to their name, require water before use), oil stones are harder and more durable. The Norton Fine-Coarse India Combination Oilstone is pre-filled with oil, so it needs no pre-soaking and helps rid the stone of dislodged metal chips and particles as you work. Made of aluminum oxide, it offers two-sided grit (100 and 320) for versatile sharpening and maintaining. It measures 8.4 x 2.5 x 1.3 inches and is highly durable, with a longer lifespan than most water stones, although it may have a slightly slower cutting rate.

    Customers say the Norton Fine/Coarse India Combination Oilstone is a great sharpening tool for both knives and tools, at a great price point that’s lower than some water stones. While it comes pre-filled, some suggest applying more oil until it’s fully saturated before using it for the first time.
