Product Warranty

Our competition uses this fragmented compound that breaks apart and wears away easily with use. Sharpeners made with Polycrystalline
Diamond will wear out and need replacement.
EASY CARE & USAGE
Your DMT® Diamond Whetstone™ is a precision tool. When used with reasonable care, it will give you many years of faithful service.
1. Break-in period: Initially your diamond stone will seem especially rough. It will smooth over time with gentle stroking without
impacting performance. You need not exert extra pressure - let the diamonds do the work!
2. Use only light pressure when sharpening. As a rule, 5-10 minutes on a conventional oilstone is equal to about 20 seconds on
DMT® Diamond Sharpeners.
3. Use only water as a lubricant. A lubricant is only necessary to speed the process of clearing swarf (material removed during
sharpening) into the recessed dots.
4. After use, rinse and dry your diamond sharpener. Store dry. When further cleaning is needed, use an abrasive cleaner (non-
petroleum base) and a scrub brush. Always store your diamond sharpener clean and dry or the metal fines removed during
sharpening will rust if left on the surface.
