Dexter-Russell Diamond Knife Sharpener

A standard steel rod primarily realigns the edge of a blade, while this diamond-coated version actually removes a microscopic amount of metal to sharpen the edge while honing it. This makes it more effective for restoring dull knives rather than just maintaining an already sharp edge.

While it is built to withstand the rigors of high-volume professional kitchens, it is an excellent tool for any home cook who wants to maintain their knives properly. Its durable construction and safety features make it a practical, long-lasting addition to any home culinary toolkit.

The 12-inch length is standard for professional sharpening steels and provides ample surface area to sharpen long chef's knives in a single, smooth stroke. While it requires a bit of counter space, the length actually makes the sharpening process safer and more controlled.

For daily maintenance, a few light passes before or after use will keep your edge aligned and sharp. If your knife has become noticeably dull, you may need to use it more frequently to restore the edge, though it is not a replacement for professional grinding if the blade is severely damaged.

Always hold the sharpener by the handle, ensuring your fingers are behind the integrated finger guard. Maintain a consistent angle—typically around 20 degrees—and use light, controlled pressure to avoid slipping or damaging the blade.
