If you're looking for something 'tactical,' then you're going to want a folder (since fixed blade carry in public is iffy in most places).
For outdoor use, get a nice fixed blade, not a tactical beast. It'll serve you better and you won't get tired of it once the "i want a big, black blade that I can take with me when I jump out of airplanes into the jungle" phase wears off.
Benchmade 210. Pretty little thing. You can carry it on your belt, or in your pocket, or tossed into your pack.
Anything from Bark River. They have a wide assortment of shapes and sizes, so you're sure to find something you like. The knives are made with excellent materials (tool steel, usually A2 if I'm not mistaken, and a huge variety of handle materials), and are extremely well-crafted. And, their prices are in your ballpark, if you shop around online for a minute.
You could get a Becker or a Busse and you might be able to chop through a concrete bunker and 'covertly deanimate' its residents, but a Bark River will be a reliable tool to cover all your outdoor needs. It'll take care of any task you can throw at it, and it'll look damn good to boot.
Peace.
