Actually, I think in this case it is US the consumers creating most if not all of the hype. Makers are just trying to cater to our requests. Every knife request thread on the forums, someone is saying 'too bad it isn't M4', or I hope they release a M390 version' or my favorite 'awe it ONLY comes in crappy S30v so Im not gonna buy it'. How do you expect the makers to respond?
I agree. The market for steels with better edge retention is responsible for the change in products.
