Setup and First Use
- Unpacking: Carefully remove the knife from its packaging. Be mindful of the sharp blade.
- Initial Cleaning: Before first use, wash the knife by hand with warm water and a mild detergent. Rinse thoroughly and dry immediately with a soft cloth. This removes any manufacturing residues.
- Inspection: Inspect the blade and handle for any damage. If any issues are found, contact customer support.
Operating and Usage
The ZWILLING Pro Le Blanc 5-inch Serrated Utility Knife is designed for precision and comfort.
Proper Grip
Utilize the unique curved bolster for a professional pinch grip. Place your thumb and index finger directly on the blade, just in front of the bolster. This grip provides optimal control, balance, and safety, reducing hand fatigue.
Cutting Techniques
- Slicing: The serrated edge excels at cutting through foods with tough skins or crusts, such as bread, tomatoes, and citrus fruits, without crushing the soft interior. Use a gentle sawing motion.
- Utility Tasks: This 5-inch knife is versatile for various small to medium-sized tasks, including slicing sausages, cheese, and preparing vegetables.
- Rocking Motion: The broad curve of the blade's front facilitates the Western rocking motion for efficient chopping and mincing.
- Asian Chopping Motion: The straight back of the blade is suitable for the Asian chopping motion, allowing for precise up-and-down cuts.

Maintenance
Cleaning
- Hand Washing Recommended: To preserve the sharpness and finish of your knife, hand washing is strongly recommended. Wash immediately after each use with warm water and a mild dish soap.
- Avoid Dishwasher: The high heat and harsh detergents in dishwashers can dull the blade, damage the handle, and cause corrosion.
- Drying: Always dry the knife immediately and thoroughly with a soft cloth after washing to prevent water spots and rust.
Sharpening
Even high-quality knives require occasional sharpening to maintain their edge. For serrated blades, specialized sharpening tools or professional sharpening services are recommended. Avoid using standard knife sharpeners designed for straight edges, as they can damage the serrations.
Storage
Store your knife safely to protect the blade and prevent accidental injury. Options include a knife block, magnetic strip, or blade guards.

Safety Precautions
- Always cut away from your body.
- Use a stable cutting board.
- Keep fingers clear of the blade path.
- Never try to catch a falling knife.
- Store knives out of reach of children.
- Do not use the knife for tasks it is not designed for (e.g., opening cans, prying).
Troubleshooting
- Dull Blade: If the knife feels dull, it requires sharpening. For serrated blades, seek professional sharpening or use a specialized serrated knife sharpener.
- Rust Spots: Rust spots can occur if the knife is not dried immediately after washing or if left in a damp environment. Minor spots can sometimes be removed with a non-abrasive cleaner and immediate drying. Prevent by always hand washing and drying.
- Loose Handle: If the handle feels loose, contact ZWILLING customer support for assistance. Do not attempt to repair it yourself.
