I'm going to have to leave my knives for about 7 months. They're high-end Japanese carbon steel. What's the best way to prep them for their long desertion?

I'll adopt them and give them a good foster home until you return.

tsubaki oil aka camelia oil.  Mineral oil is okay, but I think it will evaporate eventually.  That's just a guess. It definitely doesn't polymerize, dunno where else it could go.
