Frequently Asked Questions
Are OTF knives legal?
OTF automatic knives are legal in many states but prohibited in others. Laws vary by state and sometimes by city. Check your local regulations before purchasing. We cannot ship to restricted jurisdictions.
What’s the advantage of double-edge?
Double-edge blades cut on both sides, allowing cuts in any direction without repositioning. This maximizes capability but makes the knife less suited for some utility tasks where single-edge is preferred.
How reliable is the OTF mechanism?
Quality OTF knives use precision-engineered internal mechanisms for consistent deployment. Keep the mechanism clean and avoid debris in the blade channel for best reliability.
How do I maintain an OTF knife?
Keep the blade channel clean and free of debris. Light oil on the blade and mechanism periodically. Avoid forcing the blade if it encounters resistance – clear any obstruction first.
