Lightweight and easy-to-use steel features a highly efficient ribbed surface for re-sharpening and a smooth surface for honing. Kyocera’s ceramic sharpening rods are made of advanced ceramic, a material close in hardness to diamond.

When your steel knife or cutting tool is dull, use the ribbed side to create a finely ribbed texture on the cutting edge. Then use the smooth surface to hone or finish the edge. If intense sharpening is not required, then honing should be sufficient
