All kidding aside, if you can legally carry it, get a decent FB. While the knife itself it important & you want something big enough to do some damage & be comfortable in your hand, the sheath system is important, too. How you're going to carry it.
I no longer have one, but for the $, it's hard to beat a RAT3 or RC3 with a Tek-Lok & carry it horizontally. I recommend the RAT/RC because it's a good all around EDC, not just for SD, but will do the job.
If it has to be a folder & it can be an auto, that's an idea (Although even though I can legally carry one, I don't like them as I've had 1 or 2 break on me & it always seemed to be at a bad time). One of the ZT or Kershaw A/O's aren't bad, either.
However, for the $ & ease of pocket carrying it (Clipped inside my pocket & still being out of the way so I can put my hands in that pocket), I agree that the BM 710 is hard to beat. It has a decent length blade, great blade steel, & is slim carrying. Also, the axis lock is strong, quick, & ambidextrous. Others that come to mind are the Military & Endura. Although it carries wider than the 710, other than that, a waved Endura's a great choice. If you do decide on a waved Endura, try it with the wave forward. You'll find that it opens/waves easier.
Good luck with whatever you get.
