Ive had my kershaw mini cyclone for a couple of months now and its starting to acquire little rust spots. I havent got the knife wet and I keep it oiled. I know that living in Florida surrounded by all the salt water doesnt help, but is there anything else I can do to keep it from getting these little rust spots?
 
The same happened to my Kershaw, actually it came from Wal-Mart like that from being handled in the store. Of course, it was on clearance so I didn't mind.
I rubbed it with a silicone gun cloth, was able to rid it of some of the specks, and hopefully that should help protect it from further damage.
 
Barely visible brown spots appeared also on my Cyclone. I simply washed them off with dishwashing liquid.
 
If you live in a humid area, I would strongly suggest getting a Marien Tuff Cloth! I also very much like Flitz for cleaning knives.
 
Coat the blade with spray on silicone. The best I have found for this is at my local dive shop. It is a food grade (Safe) silicone. Used just for this purpose of protecting metals
in salt water. It goes on wet then dries clear, sealing the metal.

I used to use a Kershaw amphibian for diving. After a saltwater dive as well as fresh water and after the silicone treatment my knife never rusted after a dive even after leaving it in it’s sheath for about a week. Not all silicone sprays are equal. I used one from a hardware store and it did rust after a dive. Ask your dive shop?

Hope this helps?

I switched to a Mission MPK10-Ti Titanium knife. No more rust problem.
It is just one less thing to worry about.

There are many things you can do, but they are time consuming/costly :

-reharden the steel
-use a passification process on the steel
-have it mirror polished

In reality, none of these are functional options for most users unless you have a job or have a friend who does which allows you to do the above efficiently. The most you can really do is clean the steel well and use a more powerful rust inhibitor. However as soon as you use the knife it will be burnished off almost immediately so practically you either have to put up with the rust or switch to a more corrosion resistant steel.

I polish my stainless carry blades every week to month depending on how humid it gets, or anytime they start to show rust spotting. I prefer Simichrome, although I rather like mother's Mag Wheel polish, seems to cut steel a bit faster than polishes like flitz and simichrome, and the smell is much better.
 
The best results I've gotten are these two products.Marine tuff glide/cloth and Eezox.They seem to have a lasting effect also after treatment.
