Care & Maintenance
Use clean water as the sharpening lubricant before and during sharpening. Rinse each stone thoroughly after use to remove metal particles and abrasive residue, then allow both stones to dry completely before storage. Periodically inspect the sharpening surfaces for flatness and resurface when necessary to maintain optimal sharpening accuracy. Store the stones in a clean, dry location to preserve long term performance and reliability.
