5. Operating Instructions

5.1 Opening the Blade

The CK400 features ambidextrous thumb knobs for easy one-handed opening:

1. Hold the handle firmly.
2. Place your thumb on one of the thumb knobs located near the pivot point of the blade.
3. Apply outward pressure with your thumb to swing the blade open until it fully extends and the frame lock engages with an audible click.
4. Visually confirm that the frame lock is fully engaged, securing the blade in the open position.

5.2 Closing the Blade

To safely close the blade:

1. Hold the knife handle firmly with one hand, ensuring your fingers are clear of the blade's path.
2. With your thumb, push the frame lock bar (the part of the handle that has moved inward to secure the blade) sideways to disengage it from the blade's tang.
3. While holding the lock bar, gently fold the blade back into the handle until it is fully closed.
4. Ensure the blade is completely nested within the handle before storing.

5.3 Using the Pocket Clip

The integrated pocket clip allows for convenient and secure carry. Simply slide the clip over the edge of your pocket, belt, or gear to keep the knife readily accessible.

6. Maintenance

Proper maintenance will ensure the longevity and performance of your Smith & Wesson CK400 knife.

• Cleaning: After each use, especially if exposed to moisture, dirt, or corrosive materials, clean the blade and handle with a damp cloth. For thorough cleaning, use mild soap and water, then rinse and dry immediately.
• Drying: Always dry the knife thoroughly after cleaning to prevent rust, particularly in the pivot area and under the handle scales.
• Lubrication: Periodically apply a small amount of light machine oil or knife-specific lubricant to the pivot point of the blade to ensure smooth opening and closing.
• Sharpening: The blade will dull with use. Sharpen the blade as needed using a quality sharpening stone or system. If you are unsure, seek professional sharpening services.
• Storage: Store the knife in a dry environment, away from extreme temperatures and humidity.

7. Troubleshooting

• Blade Stiffness: If the blade becomes stiff or difficult to open/close, apply a small amount of lubricant to the pivot area and work the blade open and closed several times to distribute the oil.
• Dull Blade: If the blade no longer cuts effectively, it requires sharpening. Refer to the Maintenance section for guidance.
• Loose Screws: Periodically check all screws on the handle and pocket clip. If any are loose, carefully tighten them with the appropriate tool (often a Torx bit). Do not overtighten.
