Funny, this link lists a lot of "military issued" knives that contain all the ones you mentioned, I think:

But talking to a few soldier pals and some research, most soldiers just get their own. But there were a few knives that certain divisions prefer, for example, SEALs apparently really like the SEAL pup elite.
But a marine told me whenever, well at least spec ops, go out on missions they basically make a list and get whatever they want (but again, probably only applies to those elite soldiers).
LOL, you're grandmother was like, "Grandson, let me tell you, that knife you got is freaking badass!" That's excellent. And yeah, makes sense, was probably like smart phones, everyone and their fish had a 110, but for good reason.
I think with the k-bar and my big 119, I'm set for any situations requiring me to say "You call that a knife???.....THIS is a knife!!"
So I saw a glock and the slide was parkerized and my limited understanding is it prevents that "blueing" like on my own glock. Pretty neat.
