Ruizhen collaborates with certified enterprises to maintain recognized industry standards.
Warranty coverage: Ruizhen offers a two-year warranty on its items, giving customers assurance in product reliability.
One of Ruizhen's greatest strengths as an OTF knife manufacturer is their robust OEM/ODM service:
Blade Customization: Clients can specify blade types (such as drop-point, dagger, tanto), steels, finishes, edge geometry, and coatings.
Handle Materials & Design: Choose from a range of handle materials like aluminum, G10, or other custom options. Clients can tailor handle shape, color, texture, and ergonomics.
Mechanism Options: Both single-action and double-action OTF mechanisms are supported. Additional functional elements like glass breakers or seat-belt cutters can be added.

Flexible Production: Ruizhen accommodates different order volumes — from small, bespoke runs to large-scale wholesale production, thanks to its flexible MOQ.
After-Sales Support: The company helps with product launch, logistics, and post‑sales concerns, giving OEM partners a seamless experience.
Always Handle with Care: When deploying your OTF knife, hold it securely with your non-dominant hand and keep it pointed away from your body. This minimizes the risk of accidental injury during use.
Keep Fingers Clear: Ensure that all fingers are clear of the blade's path when deploying or retracting the knife. This precaution is crucial to avoid cuts or injuries.
Use in Safe Environments: Avoid using your OTF knife in crowded or confined spaces where accidental contact with others could occur. Always maintain a safe distance from bystanders.
Regular Maintenance: To keep your OTF knife functioning smoothly, regularly clean and lubricate the blade and internal mechanisms. Use a light oil specifically designed for knives to prevent rust and ensure smooth operation.
Inspect Before Use: Always inspect your knife before use. Check for any signs of damage, such as a dull blade or malfunctioning mechanism. If the knife does not deploy or retract smoothly, do not use it until it has been serviced.
Store Properly: When not in use, store your OTF knife in a dry, cool place. Consider using a protective sheath or case to prevent dust accumulation and accidental deployment.
Avoid Improper Use: Do not use your OTF knife for tasks it is not designed for, such as prying or twisting. This can damage the blade and the internal mechanism, leading to malfunction.
Educate Yourself on the Mechanism: Familiarize yourself with the specific mechanism of your OTF knife. Understanding how it operates will help you use it safely and effectively.
Pass with Caution: If you need to hand your OTF knife to someone else, ensure the blade is retracted. If it must be passed open, hold the blade and point it away from the other person.
Follow Local Laws: Be aware of the legal regulations regarding the carry and use of OTF knives in your area. Compliance with local laws is essential for responsible ownership.
By following these precautions, you can ensure that your OTF knife remains a reliable tool for various tasks, from outdoor adventures to everyday use.
