Usage & Maintenance Instructions
1. No Soaking Required: This is a water-lubricated Flat diamond sharpening stone. No pre-soaking needed. Simply spray clean water on the surface before use for instant sharpening.
2. Wet Sharpening Recommended: Water lubrication reduces grinding heat to prevent blade annealing and edge damage. It also flushes away metal debris to avoid clogging and ensure consistent grinding accuracy.
3. Proper Storage: Rinse and dry the stone thoroughly after each use. Store it in a dry and ventilated place to avoid resin aging caused by long-term moisture.
