Query: Rusting!

I bought this set from Bed Bath and Beyond. We used several knives, hand washed them and let them dry overnight on a rack in the sink. One knife had a large rusty stain on it in the next morning! My wife and I could not believe it. It would not happen even to one of our dollar store knives! So much for the steel made in China! We were able to return the set and bought Henckels from Amazon and have been satisfied with them. I made sure, the set is made of German steel in Germany.
