Care & Maintenance
Wipe clean & dry after use; S35VN is corrosion resistant but benefits from basic care.
Light oil on the pivot keeps deployment smooth and consistent.
Edge touch-ups with a fine stone or ceramic rod restore a razor finish quickly on S35VN.
Check fasteners (clip/body screws) periodically; snug to spec if needed.
Safety Notes
Ensure the blade locks fully open before cutting.
Cut away from your body and keep fingers clear of the edge path.
Know your local carry laws regarding blade length and knife types.
