3. Setup and Blade Installation

Initial Inspection:

Before first use, inspect the knife for any signs of damage or manufacturing defects. Ensure all components are securely fastened.

Installing a New Blade:

1. With the knife in the closed position, locate the quick-release button/lever near the blade housing.
2. Press and hold the quick-release button/lever.
3. Carefully slide out the old blade (if present). Dispose of used blades safely in a designated container.
4. Insert a new standard utility blade into the slot, ensuring it aligns correctly with the internal mechanism.
5. Release the quick-release button/lever. The blade should click securely into place.
6. Gently pull on the blade to confirm it is firmly seated and locked before use.

4. Operating Instructions

Opening the Knife:

1. Hold the knife firmly with one hand.
2. Use your thumb to push the thumb stud or flipper mechanism (if present) to swing the blade open.
3. Continue opening until you hear a distinct "click," indicating the lock-back mechanism has engaged and the blade is securely locked in the open position.
4. Verify the blade is locked by gently attempting to close it without disengaging the lock.

Using the Knife:

• Apply steady, controlled pressure when cutting.
• Always cut away from your body and fingers.
• Ensure the cutting surface is stable and clear of obstructions.
• Avoid twisting or prying with the blade, as this can cause it to break or dislodge.

Closing the Knife:

1. Locate the lock-back release lever on the spine of the handle.
2. Press down on the release lever to disengage the blade lock.
3. Carefully fold the blade back into the handle until it is fully enclosed. Keep fingers clear of the closing blade path.

5. Maintenance

Cleaning:

• After each use, wipe down the blade and handle with a clean, dry cloth to remove any debris or moisture.
• For stubborn grime, use a mild soap solution and a soft brush, then rinse thoroughly and dry immediately.
• Ensure the pivot point and lock mechanism are free of dirt to maintain smooth operation.

Blade Care:

• Replace dull or damaged blades promptly to ensure safe and effective cutting. Refer to the "Setup and Blade Installation" section for instructions.
• Store new blades in their original packaging or a safe container.

6. Troubleshooting

Blade Does Not Lock Open:

• Check for debris obstructing the lock-back mechanism. Clean as described in the Maintenance section.
• Ensure the blade is fully extended until the "click" is heard.

Difficulty Changing Blade:

• Ensure the quick-release button/lever is fully depressed.
• Check for any rust or corrosion on the blade or internal components. Clean and lubricate if necessary.

Blade Appears Loose:

• Verify the blade is correctly installed and the quick-release mechanism is fully engaged.
• If the blade is still loose, it may be worn or damaged and should be replaced.
