I was honing a razor just a little while ago that I had hand-sanded to a decent shine. My son stopped by to borrow a book so I was interrupted for maybe 5 minutes--- yeah I forgot to wipe the blade off before I set it down ---- the razor rusted in that 5 minutes! It cleaned up (for the most part) very easily, but I was a little shocked. Does the sanding make the blade more prone to this?
