Are the razors identical?

If you are putting the washers "at the pivot points," aren't the scales preventing contact with the tang?

Since the concern is with microscopic corrosion at the edge, why wouldn't you put the washer nearer to the edge, like at the spine, rather than at the pivot?

Are you misting with water or salt water?

Why mist at all? If you are concerned about ocean air rusting razors then why not expose them to ocean air?
