Integrated Sharpening System

Care and Maintenance
Cleaning
The knife and sheath are dishwasher safe. However, hand washing is recommended to prolong the life and appearance of the product.
- Hand Washing: Wash the knife and sheath with warm water and mild dish soap. Use a soft sponge or cloth. Rinse thoroughly under running water.
- Drying: Immediately dry the knife completely with a soft cloth after washing to prevent water spots and corrosion. Ensure the sheath is also dry before storing the knife.
- Dishwasher: If using a dishwasher, place the knife securely in the cutlery basket with the blade pointing downwards. Place the sheath in a stable position. Use a gentle cycle and avoid harsh detergents. Remove and dry immediately after the cycle.
Storage
Always store the knife in its Ever Sharp sheath when not in use. This protects the blade, maintains its sharpness, and ensures safe storage.
Troubleshooting
- Issue: Knife does not feel sharp after use.
- Solution: Ensure the knife is fully inserted and removed from the sheath several times. The sharpening mechanism works during both actions. If the issue persists, ensure the sheath is clean and free of debris that might obstruct the sharpening elements.
- Issue: Knife is difficult to insert or remove from the sheath.
- Solution: Check for any food debris or foreign objects inside the sheath. Clean the sheath thoroughly. Ensure the knife is inserted straight and not at an angle. The locking mechanism should engage smoothly.
- Issue: Rust spots appear on the blade.
- Solution: Although made of stainless steel, prolonged exposure to moisture or acidic foods can cause discoloration or rust. Always wash and dry the knife immediately after use. Avoid leaving it soaking in water or in contact with acidic residues. If rust spots appear, they can often be removed with a non-abrasive cleaner designed for stainless steel.
