Parents had a 30+ year old set of Chicago Cutlery knives. It was a standard knife set including a knife block, and all of the handles were made of wood. I decided to test their lifetime warranty policy. Googled for an 800 number, called it, talked to a rep who wanted the item number and other info. I said it was at least 30 years old and didn't have any markings on it other than giant Chicago Cutlery stamps on the block and each of the knives. She shipped me a brand new set of knives, with more than the old set, and asked that I return the old one with the pre-paid shipping label.

Go Chicago Cutlery!
