CPM steels seem to be all the latest trend, but, there are other steels out there that are better (in many cases) and less expensive. If you look at the Ka-Bar BK&T philosophy, it isn't really wrapped up in getting the latest steel or material out there. The idea is that they can make a blade that a lot of people will enjoy, many can buy, and it will be a good price.
I personally am not fond of D2 at all. I know it has high wear resistance, but, from what I have experienced (never had a D2 Ka-Bar), it is brittle to the point of near uselessness. I keep throwing this out there because the Sweedish steels are so overlooked, but AEB-L/13C26 and 14C28 would be great value options for a blade made by BK&T/Ka-Bar. Don't believe me? Like Ethan said, the German DIN 1.4116 kitchen knives are in the same class and loads of people love them and if given a higher hardness, I think it would be a good option (I'd prefer the Sandvik options).
I am not trying to talk down to the other members of the board who posted about S30V, but, for a production run of a folder in that steel, I think it is safe to say to dream on. I would love to see it happen, but I just don't think it is a possibility.
I have used AEB-L in my personal knife making (similar to 13C26 and 14C28) and it is incredibly tough and wear resistant. Unbelievably, it even outperforms S30V when I tried to cut kydex with it. My AEB-L knife at 59hrc is the only knife I cut tough materials with and the edge lasts. There is another post on the forums somewhere comparing this steel to others and I never heard a bad comment about it. Steels like CPM S30V are nice, but for the price of the Swedish mid level carbon steels, I don't think you can go wrong, especially if you heat treat them to around 59.
A ti frame lock would be sweet, but again, material costs would be kinda high, so SS or even a normal liner lock would be fantastic as well, just as long as it is made in the states and by BK&T/Ka-Bar and as long as it has the traditional BK&T style...
