I just got a Lee Valley tools catalog, and one of the new items might be of interest to people with rusting problems. I haven't used it (I oil my blades, no problems so far).

I don't know how it works, but it's a very nice idea.

Anti-Corrosion Liner - Lee Valley Tools

Anti-Corrosion Liner

Used in an enclosed space such as a drawer, cabinet shelf, toolbox or tackle box, this liner is a convenient and economical means of guarding metals against rust and corrosion damage. The rubber/PVC mesh gives off a harmless corrosion-inhibiting vapor that forms an invisible barrier on ferrous and non-ferrous metals, providing up to five years of continuous protection.Available in two sizes, the non-slip liner keeps items in place and can be easily cut to size with scissors. Mold and mildew resistant, and washable.
Made in USA.
The initial shipment is currently en route to our retail stores. We expect to have stock available at all locations by mid-January, 2012.
