I recently acquired a "broken-in" C/U 7 from a forum member. A significant amount of the blade coating has worn off. Since it is a high carbon steel blade, should I be concerned with rust? I don't want to have to worry about "maintaining" the blade. Anyone have any suggestions? I was thinking about alternative blade coatings (boron carbide, namely), but haven't decided on it. Heck , maybe a coat of Krylon BBQ paint will suffice!
FWIW, this will continue to be a user knife, so I'm not at all concered with its appearance.
Any advice???
