Which, as far as I've ever heard it, would make it a "folding utility knife". I've also never seen a combat knife without a fixed blade, because... "Hold on let me just unfold my pocket knife so I can combat you!"
Any folding knife, again, as far as I've ever seen, would be more likely to be called a tactical knife. Which is just another word for utility folder IMO.
Eh, depends. I used to carry a similar knife when I was a vol FF, because seat belt cutter + glass break is handy, and the blade worked better for clothing caught in something than the belt cutter (belt cutter works best when its taut and flat, since its basically a coupon cutter).
Worked just great for the intended purpose. What its not, however, is more than just a utility folder.
