Query: They rust!

TheyChicago Cutlery Landmark 12-Piece Knife Block Setall have gotten full of rust spots. I have old wood-handled chicago cutlery, which doesn't rust. I received the brand new set as a gift, but I'm disappointed that they are covered with rust since the first time through the dishwasher. The company doesn't care, I called and they told me to get barkeeper's friend to remove the rust, and to wash and dry them by hand. Really!!! My old set goes through the DW perfectly!
