    If you’re investing in a high-quality chef’s knife, you should maintain it right with a good knife sharpener. Sharpening your own knives may seem intimidating, but once you get over the initial learning curve, it can be a cost-effective way to transform your dull knives into a new razor-sharp set. 

    As long as I can remember, I’ve been obsessed with the idea of a sharp knife. My dad, a former butcher, taught me to sharpen knives, starting around age 6. We used his sharpening stone, which he kept at my grandma’s house in upstate New York, when we visited her on weekends. There, I learned first on a small Swiss Army knife before I was allowed to practice on her larger boning and chef’s knives.

    Since then, I’ve used hundreds of knives—in culinary school, in professional kitchens, and now at home, as the resident chef—and I can tell you that the real magic isn’t always in the knife so much as in the sharpening. That’s not to say any knife is fine—we found significant differences and clear favorites in CR’s evaluation of chef’s knives. But I’d rather cut with a crummy knife that has been recently sharpened than a stellar knife with a dull blade.

    ​​We tested eight knife sharpeners—two electric, three manual, and three stone models from brands like AccuSharp, KitchenIQ, and Sharp Pebble—to find the best knife sharpeners on the market. Below, you can read reviews of our top picks. We’ve also compiled tips on shopping for a new knife and proper knife technique and care, to ensure years of effortless cutting.

    Best Knife Sharpeners (and the Worst)

    Every sharpener I tried did a decent job of returning an edge to the test knives, but some sharpeners clearly produced a finer edge than others, and a handful were tedious to use. At times, some even felt dangerous.
