The Best Knife Sharpener

Sharpening your own knives may seem intimidating, but it’s a cost-effective way to take what could be trash (your dull knives) and turn it into treasure (a brand new set!). Manual and electric knife sharpeners are easier to use than sharpening stones, and the best ones are quick and versatile. After testing 11 sharpeners—and slicing through 10 pounds of tomatoes—we think the Chef’sChoice Trizor XV is the best for home cooks. It gently puts a razor edge on dulled knives of almost every sort: Japanese- and German-style, stamped and forged, cheap and expensive.
