There was some talk about this model a while back. I think the conclusion was that this SAK has no actual association wit the US Military.
I checked the exchange (PX & BX) system, and it is not for sale through those channels (although a few other SAKs are).
Since this knife does have an NSN, individual units could order these if they chose, but that's true of a a wide number of knives and tools.
Still, kind of a cool knife!
