Case will simply use the steels and terminology that suits its primary target customers: collectors and the average Joe looking for a traditional user. They aren't seriously interested in penetrating any niche market that values the latest and greatest or most exotic blade material. If you're a collector, then you probably aren't going to subject your blades to any cutting stress more challenging than slicing newsprint or shaving arm hair. And if you're the average "Joe Blow from Kokomo" then you probably wouldn't benefit from, much less care to spend the bucks for, more than 420HC or 1085 steels anyway. If Case thought advertising the precise alloy composition or the actual steel's brand name would sell more knives, then they'd surely do it.
