I've used my superblue blades quite extensively, and a patina is the best way to keep them up in my opinion. Without patina, they require constant vigilance in order to avoid rust - unless you burnish them, and then you only have to be moderately vigilant. With patina, you can oil them normally.
"Nothing is so fatal to the progress of the human mind as to suppose that our views of science are ultimate; that there are no mysteries in nature; that our triumphs are complete, and that there are no new worlds to conquer."
