The WÜSTHOF Sharpening Guide is used to help glide your knife along a WÜSTHOF whetstone and ensures the proper 14-degree angle is used while sharpening the knife. The soft silicone surface prevents the knife from scratches and helps to keep a secure grip on the guide while sliding along the whetstone. The angled guide makes using a whetstone effortless and allows for easy knife maintenance. 

• Before using your whetstone, be sure to soak it in water to ensure it stays wet while sharpening knives.
• Always use the entire surface of your whetstone.
• After use, rinse under running water and leave to air dry.
• Use the whetstone’s holding tray to store it. We recommend a box to protect your stone when not in use.
• If necessary, use a rubbing stone to roughen the surface and remove any unevenness.
