4. Setup

4.1 Unboxing

Carefully remove the knives from their packaging. Knives are sharp; always handle them by the handle and keep fingers away from the blade edge.

4.2 Initial Cleaning

Before first use, hand wash the knives with warm water and a mild detergent. Rinse thoroughly and dry immediately with a soft cloth to prevent water spots and maintain the blade's finish.

5. Operating Instructions

5.1 General Use & Safety

• Always use a stable cutting board made of wood or plastic. Avoid cutting on hard surfaces like glass, stone, or metal, as this can dull or damage the blade.
• Maintain a firm grip on the handle. Keep your guiding hand's fingertips curled inward, using your knuckles as a guide for the blade to prevent accidental cuts.
• Cut away from your body.
• Never try to catch a falling knife. Step back and let it fall.
• Do not use knives for tasks they are not designed for, such as opening cans or prying.

5.2 5.5-inch Prep Knife

The 5.5-inch prep knife is versatile for smaller, more intricate tasks. It is ideal for mincing shallots, garlic, and herbs, as well as peeling and slicing small fruits and vegetables.

5.3 7-inch Rocking Santoku Knife

The 7-inch rocking Santoku knife features a curved blade designed for a rocking motion, making it excellent for chopping, dicing, and mincing. Its broad blade is also useful for scooping ingredients from the cutting board. The hollow-ground (Granton) edge helps prevent food from sticking to the blade.

6. Maintenance

6.1 Cleaning

Hand washing is recommended. Although some ZWILLING knives may be dishwasher safe, hand washing is always preferred to preserve the sharpness of the blade and the integrity of the handle. Wash immediately after use with warm water and a mild detergent. Rinse thoroughly and dry completely with a soft cloth to prevent corrosion and water spots.

6.2 Sharpening

Regular sharpening is essential to maintain optimal performance. Use a sharpening steel or a suitable knife sharpener to keep the edge keen. For best results, consider professional sharpening periodically.

6.3 Storage

Store knives safely to protect the blade and prevent injury. Options include a knife block, magnetic strip, in-drawer knife organizer, or blade guards.

7. Troubleshooting

7.1 Dull Blade

If your knife feels dull, it likely needs sharpening. Refer to section 6.2 for sharpening recommendations. Regular honing with a sharpening steel can maintain the edge between sharpenings.

7.2 Rust Spots

While ZWILLING knives are made from high-carbon no-stain steel, prolonged exposure to moisture or acidic foods can cause surface rust. To prevent this, always hand wash and dry your knives immediately after use. If rust spots appear, they can often be removed with a non-abrasive cleaner designed for stainless steel or a rust eraser.
