Product Overview
The ZWILLING TWIN Signature 8-inch German Chef Knife is precision-stamped from a single piece of high-carbon German stainless steel. This design results in a lighter weight knife that maintains exceptional sharpness and durability. The proprietary special formula steel, perfected over 280 years, combined with ZWILLING's signature ice-hardening technique (FRIODUR), ensures the blade is harder, sharper, resistant to staining and chipping, and retains its sharpness longer. The ergonomic polymer handle, secured with three rivets, provides optimum durability and comfort.

Setup
Before first use, carefully remove all packaging materials. Wash the knife thoroughly with warm water and a mild dish soap. Rinse completely and dry immediately with a soft cloth. This initial cleaning removes any manufacturing residues and prepares the knife for safe use.
Safety Precautions:
- Always handle the knife with care, as the blade is extremely sharp.
- Keep fingers away from the blade edge during handling and cleaning.
- Store the knife in a knife block, magnetic strip, or with a blade guard to protect the edge and prevent accidental injury.
Operating Instructions
The 8-inch chef knife is a versatile tool suitable for a wide range of kitchen tasks, including chopping, dicing, mincing, and slicing. Its balanced design and sharp edge make it efficient for preparing various ingredients.
Proper Grip:
For optimal control and safety, hold the knife with a pinch grip. Place your thumb and forefinger on opposite sides of the blade, just in front of the bolster (where the blade meets the handle). Wrap your remaining fingers around the handle. This grip provides stability and precision.
Cutting Techniques:
- Rocking Motion: For chopping herbs or mincing garlic, use a rocking motion. Keep the tip of the blade on the cutting board and lift the heel, moving the knife up and down while rocking it forward and backward.
- Slicing: For slicing vegetables or meats, use a smooth, forward-and-down motion, drawing the blade towards you. Avoid pressing straight down, as this can damage the blade and the food.
- Dicing: Create even cuts by first slicing, then turning the food and slicing again to create uniform pieces.

Maintenance
Cleaning:
To preserve the quality and sharpness of your ZWILLING TWIN Signature knife, hand washing is strongly recommended. Wash immediately after each use with warm water and a mild detergent. Avoid abrasive cleaners or scrubbers that could scratch the blade or handle. Rinse thoroughly and dry completely with a soft towel to prevent water spots and corrosion.
Do not wash in a dishwasher.
Dishwashers can expose the knife to harsh detergents, high temperatures, and potential contact with other items, which can dull the blade, damage the handle, and lead to corrosion.
Sharpening:
Regular sharpening and honing are essential to maintain the knife's optimal performance. Use a sharpening steel or a suitable knife sharpener to keep the edge keen. For best results, follow the manufacturer's guidelines for sharpening angles (typically 15 degrees per side for ZWILLING knives).
Storage:
Store your knife safely to protect its edge and prevent accidents. A knife block, magnetic strip, or individual blade guards are recommended. Avoid storing knives loosely in a drawer where they can come into contact with other utensils, which can dull or chip the blade.
Troubleshooting
- Dull Blade: If the knife feels dull, it needs sharpening. Refer to the 'Sharpening' section under Maintenance. Regular honing with a sharpening steel between sharpenings can extend the edge's life.
- Rust Spots: Although made from 'NO STAIN' steel, prolonged exposure to moisture or acidic foods, especially if left uncleaned, can cause minor surface discoloration or rust spots. Clean immediately and thoroughly dry the knife after each use. If spots appear, they can often be removed with a non-abrasive cleaner designed for stainless steel.
- Loose Handle: If the handle feels loose, it may indicate damage. Do not attempt to repair it yourself. Contact ZWILLING customer support for assistance under the lifetime warranty.
