Query: Already rusting after three months

After first opening the package I was very impressed with the weight, the feel of the knives and how extremely sharp they were. Now that I've used them for a few months I'm still impressed with how well they cut but I'm starting to notice rust spots. I have never put them in the dishwasher nor let them soak in water for any length of time. At first it was only the smaller of the knives and though I wasn't happy I could have received a single bad blade. Now all three are showing small rust spots. I have owned much less quality knives and not taken nearly as good care of them and non of the previous sets have rusted. These knives are not worth the money you pay for them. I'm still giving two stars due to the fact that the knives are well balanced and sharp but for this price I would like them to last too.
