Safety Precautions
- Always handle the knife with care. The blade is extremely sharp.
- Keep fingers clear of the blade path when opening or closing the knife.

- Do not use the knife for tasks it was not designed for, such as prying or as a screwdriver.
- Always cut away from your body.
Setup
Initial Inspection
Upon receiving your Ruike M121 knife, carefully remove it from its packaging. Inspect the knife for any signs of damage or manufacturing defects. Ensure the blade opens and closes smoothly and that the locking mechanism engages securely.
Familiarization with Components
Identify the key components of your knife:
- Blade: The cutting edge, made of stainless steel.
- Handle: The grip portion, constructed from titanium.
- Framelock: The locking mechanism that secures the blade in the open position.
- Pocket Clip: For secure carrying.
- Flipper: For opening the blade.

Operating Instructions
Opening the Blade
- Hold the handle firmly.
- Apply pressure to the flipper tab with your index finger.
- Continue the motion until the blade fully extends and the framelock engages with an audible click.
- Visually confirm that the framelock bar is securely seated against the blade's tang, preventing accidental closure.
Closing the Blade
- With one hand holding the handle, use your thumb to push the framelock bar outwards, away from the blade's tang.
- Once the lock is disengaged, carefully fold the blade back into the handle using your other hand or by gently pushing the spine of the blade.
- Ensure fingers are clear of the blade path during closure.
Using the Beta Lock (Secondary Lock)
The M121 features a secondary "beta lock" mechanism designed to prevent accidental disengagement of the framelock. To activate, slide the small lever located on the framelock bar towards the blade. To deactivate, slide it away from the blade. This feature provides an additional layer of security when the knife is open and in use.

Maintenance
Cleaning
- Hand Wash Only: Clean the knife with mild soap and water. Avoid harsh chemicals or abrasive cleaners.
- Rinse thoroughly to remove all soap residue.
- Dry the knife immediately and completely with a soft cloth to prevent water spots or corrosion. Pay special attention to the pivot area.
Lubrication
Periodically apply a small amount of high-quality knife pivot lubricant to the pivot area. This will ensure smooth blade action and prevent wear. Do not over-lubricate.
Sharpening
Maintain the blade's sharpness using a suitable sharpening system. If you are not experienced in knife sharpening, consider professional sharpening services to preserve the blade's edge geometry.
Storage
Store your knife in a dry environment to prevent rust or corrosion. Keep it sheathed or folded to protect the blade and prevent accidental injury.
Troubleshooting
- Stiff Blade Action: If the blade feels stiff, clean the pivot area thoroughly and apply a small amount of lubricant. Ensure the pivot screw is not overtightened.
- Blade Play: If there is excessive side-to-side movement in the blade when open, gently tighten the pivot screw. Do not overtighten, as this can impede blade action. If the issue persists, contact customer support.
- Framelock Not Engaging Fully: Ensure no debris is obstructing the lock bar or blade tang. Clean the area. If the lock bar still does not engage fully, discontinue use and contact customer support.
