It's easy to keep your fine cutlery in pristine condition with Wusthof's triple-sided whetstone sharpener. For all-in-one sharpening, it offers three different grits-clearly labeled "coarse," "medium" and "fine". Use the "coarse" 240-grit abrasive side for pre-sharpening and to remove small nicks. Put a finely sharpened edge on your blade with the "medium" 1000-grit side, then polish it to razor-sharp perfection with the "fine" 3000-grit side. Use the abrasive 240-grit side for pre-sharpening and to remove small nicks. Put a keen edge on your blade with the 1000-grit side, then polish it to razor-sharp perfection with the 3000-grit side. Use this versatile combination whetstone to restore Wusthof blades to their original sharpness. The coarse 240-grit side is perfect for duller blades and setting the edge. The medium 1000-grit side is designed for restoring a finely sharpened edge. The fine 3000-grit side is ideal for refreshing or finishing a razor-sharp edge. Includes a water bottle (for re-wetting the stone) and a durable wooden storage case. Made in Germany by Wusthof-a family-owned company famous for precision cutlery since 1814.
