Recommended Professional Applications
The Naniwa Professional 1000 Grit Sharpening Stone is ideal for maintaining chef knives, santoku knives, utility knives, slicing knives, cleavers, and other straight-edge culinary blades. It is particularly useful as a primary maintenance stone for knives that have become moderately dull but do not require aggressive chip repair or major edge reconstruction.
For a more polished cutting edge, the blade can be progressed to a finer-grit stone after sharpening. Severely damaged or heavily blunted blades may require a coarser stone before moving to the 1000-grit surface.
Care & Maintenance
Use the sharpening stone on a secure, non-slip base and follow the manufacturer’s recommended water-preparation method before sharpening. Clean the stone after use, remove accumulated metal residue, and allow it to dry completely in a ventilated area before storage.
Avoid placing the stone in a dishwasher, exposing it to extreme heat, or storing it while wet. Periodic flattening is recommended to maintain an even sharpening surface and consistent contact across the knife edge.
