All IOXIO® sharpening rods are made of aluminum oxide ceramic. They combine the hardness of the whetstone with the shape of the conventional sharpening steel. The ceramic sharpening rod grinds knives by material abrasion on the blade. The cutting edge is sharpened and reshaped.
IOXIO® ceramic sharpening rods are not coated. They consist of a full ceramic sharpening rod and wear out almost not during sharpening. During sharpening, the material abrasion from the knife is deposited on the ceramic. Our tip: Clean the sharpening rod regularly with a damp eraser sponge.
The white ceramic is sintered and therefore harder than any knife made of steel. It optimizes kitchen knives in fine grinding with a grain size of F1000/J3000.
