JohnnyV;

I have something like seven TI razors with that C135 steel and I have never had any rust problems with them. This steel doesn't seem to want to rust very quickly and the clean, mirror-polished finish makes it even harder for moisture to find an entry point into the surface. You can improve on an already good situation by doing as follows:

After shaving, rinse the blade under the absolute hottest water you can get out of the tap (not boiling, please). Then carefully wipe off the blade with a dry, clean towel. I always keep a couple of soft, kitchen towels in the bathroom for just this purpose. Oh yes, don't forget to check for stray droplets of water in and along the scales. For good measure, leave the razor out to air for a minute or so before slipping it into its leather sheath and putting it away.

Yes, you can put on a thin coat of oil for storage if you feel that your local conditions are extremely humid (like a bathroom which is constantly steamed up from people taking hot showers). It won't hurt. I, personally, have never used oil on my razors (except an occasional drop at the hinge) and haven't had any trouble with rust at all.

Treat these razors right and your great grandchildren will be thanking you as they shave with 'em.
