WHITE CERAMIC: The Shenzhen white ceramic knife sharpeners are harder than diamonds; the alumina ceramic is resistant to rust, stronger than regular steel, and has an HRC hardness rating of 68.
HONE AND SHARPEN: Our rods have a slightly abrasive 1000 grit rating for realigning the knife edge; sweep your chosen blade along the rod to hone the edge and reduce the need for frequent sharpening
HAND WASH ONLY: Remove gray streaks and buildup by hand washing the sharpening rod with mild dish soap and a sponge; the ceramic is breakable, so be careful not to drop the sharpener onto the floor
PROFESSIONAL USE: The 12-inch sharpener is long enough for professional use; easily hone and straighten any stainless steel knife in your kitchen including chef knives, cooking and carving knives, and hunting knives (does not sharpen serrated blades)
RECTANGULAR BLADE GUARD: The wide nylon handle fits comfortably into your hand and the rectangular blade guard is reinforced with zinc alloy to protect you from stray knife strokes while sharpening
