The Idahone Fine Ceramic Sharpening Rod works on any kind of knife (except a serrated one), and it’s gentler on blades than traditional steel honing rods.

This smooth, white ceramic rod was easy to use, with a length that gave us plenty of space. Its wood handle was comfortable and compact, with no overhand to block us from getting the right blade angle. It took slightly longer to achieve a sharper knife edge than our top-rated tool because of its smooth, less-abrasive texture, but it worked while being comparatively gentle on our knife.
