Query: Very disappointing

I was lusting after this set of knives for my kitchen for the longest time, but after getting them as a gift and using them for about a year have found them to be not very good at all. The grip handles are great, but the blades are strangely perforated and they have all rusted! It says they are made of stainless steel, so why are they rusting? I was shocked to see this low level of qaulity from a company like Henckles. I really don't recommend this product.
