Somedayrockstar, first of all, do you know your local knife laws regarding fixed-blades? Some states, counties, cities, have limitations on the length of blade you can carry. And some might forbid the carrying of fixed-blades altogether. It would really suck if you bought a knife with the intentions of carrying it, only to find out that it is illegal to do so. And it would REALLY, REALLY SUCK if you found out the hard way that your knife is illegal by being arrested and landing in jail because of it.
Aside from the legal issues, it would be a lot easier for people to recommend a knife if you were as specific as possible as to what you wanted. As you have said, there are so many options.
You have given an indication as to what you want to use the knife for, and that is a start. But you say that "size doesn't matter". That makes it a bit difficult to recommend a knife because fixed-blades come in a wide variety of sizes, some very small (like a 1" blade) and some rather large (8", 9", 10", etc, etc).
Also, it would be helpful if you stated your budget for this knife. Fixed-blades can be very inexpensive (under $50), or they can cost several hundreds, or even thousands of dollars.
