Maintaining your pocket knife through proper lubrication is crucial for its longevity and performance. This comprehensive guide will walk you through the essential steps of oiling your knife, helping you prevent rust, reduce friction, and keep your blade in optimal condition. Whether you’re a knife enthusiast with a custom folding knife or just starting with your first pocket knife, this guide will ensure your blade stays smooth and reliable.
Why Should You Oil Your Pocket Knife?
Regular lubrication is essential for several reasons. A well-oiled knife opens and closes smoothly, resists corrosion, and maintains its sharp blade longer. Without proper lubrication, your quality knife can develop rust, become difficult to operate, and potentially become unsafe to use.
What Type of Oil Should You Use on Your Knife?
Not all oils are created equal when it comes to knife maintenance. Here are the best options:
- Food-grade mineral oil
- Gun oil
- Ballistol
- PTFE-based lubricants
- Dry lubricant
Avoid using:
- Vegetable oil (can go rancid)
- Machine oil (not food safe)
- Petroleum-based products (may damage handle materials)

How Often Should You Oil Your Knife?
The frequency of oiling depends on several factors:
- Usage frequency
- Environmental conditions
- Storage conditions
- Type of steel (especially important for carbon steel blades)
