Somewhere I read Mineral Oil worked. Well, I happen to cook and have an expensive wooden cutting board which I condition with Mineral Oil. I also condition my knife handles with it.

I have always kept it in a "sprayer" which I stored under my kitchen sink. Now I just keep it in my bathroom and spritz each side of the blade when I finish (I rotate through blades so I don't use the same over and over).

I got it at a chef's supply store,... but it's online here:
