I do think people are a little silly about knife steel, but in this case I'd love to see the company's test results backing up their strong statement. At 60HRC, S30V should have (according to the data sheet) similar toughness and impact resistance to 1095 at 57HRC. So for the price you're getting a little extra hardness, a lot of extra edge retention, and much better corrosion resistance. Now, you sure could say that isn't worth it in this application. But this stuff is very real and measurable (unlike the HiFi nonsense). The crazy stuff in knife steel is often the other way: folks picking stuff like White #2, and caring only about hardness, and ending up with something they think is high end but performs quite badly on objective tests.
