3-Step Precision Sharpening System: Naanyo’s 3-slot sharpening system restores your knives to their optimal sharpness. The first slot straightens and repairs dull or slightly damaged blades, the second slot restores the knife’s V-shaped edge, and the third slot fine-tunes and polishes for a razor-sharp finish. This multi-stage process ensures each knife delivers precise, consistent cutting performance every time
