Care & Maintenance

1. Wipe the blade dry after use to preserve the stone wash finish.
2. Apply a thin coat of food-grade mineral oil to the blade weekly during regular carry.
3. Periodically lubricate the OTF slider tracks with lightweight oil for smooth deployment.
4. Clean the mammoth ivory patch with a soft dry cloth — avoid soaking or solvents.
5. Inspect the OTF mechanism for debris monthly; clear with compressed air if needed.
6. Tighten the body screws periodically to prevent handle play.
7. Store in a dry environment with silica gel packets if kept long-term.
8. Avoid prolonged contact with chlorides, salt water or acidic materials.
9. Sharpen with diamond stones at the factory angle — CPM-20CV is harder to sharpen than simpler stainless steels.
