Try a Ka-Bar USMC. It has a strong carbon steel blade, will work as a pry bar in an emergency, holds a good edge and will get pretty sharp if you know what you're doing. The Ka-bar sports a 7 inch clip-point blade, and is designed as a fighter/utility knife. It is only $50, and is a step up from the glock field knife.
If the Ka-Bar isn't for you, then Tops, Strider, or MOD may be the answer. TOPS has a lot of great designs, but many of the knives are made from 1095 steel (the same steel as the Ka-Bar), and are slightly expensive. Strider knives are comparable to a sharpened pry bar; they are strong, and have an edge, but are not aesthetically pleasing (in my opinion), and are very expensive. MOD knives are designed for fighting, and probably work great in that role, but I don't know how well they would fare as prybars.
Some other companies to consider are:
Cold Steel
SOG Knives
Ranger Knives
Chris Reeve Knives
Swamp Rat Knives
Busse Combat Knives
There are some in these forums that consider Busse to be the "Best of the Best" in the production knife category. Keep them in mind if you want an aesthetically pleasing tough-as-nails fighting prybar kind of knife (the new Hell Razor may be exactly what you are looking for).
Good luck in your quest.
