I know SF teams (some of them anyway) get the Mission MPK, or Multi Purpose Knife, but it's far from multi purpose. It's a titanium knife that's practically impervious to erosion. Nice piece of work, but metal is a bit soft. MOD also makes a tactical knife (CQD Mark VI Stinger) that can be used as a pry bar, utility knife, or fighting knife. They aren't exactly like the Leatherman's or Swiss Army knives, but they serve as pretty decent multi role fixed blade knives.
