Why are my rust proof knives rusting?

I bought a set of stainless steel knives and was really under the impression they will not rust. Not even two weeks after I bought them they have started to rust.

any steel will rust. As far as I am concerned the term stainless steel is more like a brand than a fact of the material used. The best thing to do with metal kitchen utensils is to wash them and immediately dry them and store them away from other metals. Using a knife and not cleaning it right away can cause rusting to happen, leaving a knife wet can cause rusting. I would have problems like as well until I started being real anal about keeping my knives clean and dry, now no problems at all. Keep you knives clean and dry!!

Some metal items are treated to a mineral bath as part of processing, so it's possible it's residue that is rusting.

Another thing might be they simply had a rust-proof coating, and your particular set might have partially or completely missed that part of the process. If they "never need sharpening" this is a good possibility, because if you were to sharpen them, you'd be getting past that coating and then they *would* rust.

You may wish to consider trying out ceramic knives, as an alternative to metal. They are much sharper and more durable than steel blades so they will hold a sharp edge much, much longer, and not being metal they won't rust.

The downside though is the price. They do cost a bit more than your typical kitchen knife, and they're no good for cutting hard objects such as bone as they may break. You also can't use a traditional knife sharpener on them as the material is somewhat different to metal on a microscopic scale, so this will agian just break them, so there's no sharpening eithe.

That said, they are a good investment if you are having problems with so called "Stainless Steel" knives. You should pick one up and give it a go and see if you want to make the switch.

Ceramic knives are sharper and do not rust, but they are not more durable. In fact, dropping them on the ground can shatter them.

Normal wear and tear will remove the rust-proof coating after a while.

Somehow these "miracle products" like floors that never need waxing and automobile finishes that never need polishing don't really work (forever)

TIP: Here is a environmentally-safe and great way to remove rust from almost anything that is rusty. Put it a shallow bath of molasses. Dilute it with water if you don't have enough to cover it. Wash and dry thoroughly.

There are many reasons.  One is that you heated them beyond what you're supposed to.  It will turn blue, smell strange and rust.  Two is that they could be coated in an anti rust solution and that has been scratched off.   Then the last one I have is that they are actually a lot older than you think.  It's stainless steel because it has been formed will other metals to resist rusting.  The longer they're around the more likely these anti rust metals are wearing away.  Hope this helps
