Sorry to rain on the parade here, there are a lot of good knives recommended here, but not for the purpose that the author or the origional post needs.
I'm not talking quality......
I'm not talking concealability......
I'm talking about not getting thrown into the pokey.
Those dozier knives look great, and I'll bet 9 out of 10 Texas Peace Officers will toss you in cuffs for having either of the ones shown on their main page. They even call it a Bowie knife. If the manufacturer calls it a "Bowie", likely a judge/jury would agree.
Second, most anything that looks like a dagger, even if single edged, may be seen as a dagger/dirk......thus even though you may beat the charge in court, you'll have a night or two in jail to think about how you will.
Anything beveled on both ends will raise eyebrows, this may be overlooked on some folders, but on a fixed blade can mean the difference between "have a good night sir" and "You have the right to remain silent..."
I recommend sticking with Tanto type styles, avoid a push dagger or anything with the words "dirk", "dagger" or "bowie" in the title. Again, if you think you are in the right, you may be, but cops know less about knives than they know about guns and if he arrests you because of something the manufacturer calls a dagger, whose going to blame him?
Save yourself the hassel. Even a CHL will not save you from our draconian knife laws.....some believe differently, but try it yourself if you think I'm wrong.
Something like the Becker Necker

may fit the bill, maybe not but something like the
http://www.policeone.com/police-products/duty-gear/knives/press-releases/90711/ Kershaw boot knife, even though technically legal (because I believe the other side, while beveled is blunted) will land you in jail because, to most cops, that's technically a dagger.
