If you're referring to the famous Solingen steel, etc., then its been superseded by more modern products. Nothing wrong with it, as its high quality, but my understanding is that it's basically good 420 stainless like you'd find in a Buck knife at Wal-mart. This description doesn't apply to specialty products from German companies like Bokker, etc., which may be very modern indeed. I'm by no means an expert on the subject and someone with more knowledge may want to correct me on some of the details.
