I've found that what makes or breaks a FB for daily carry in my case is the sheath, even more than the knife. It has to be comfortable to carry standing or sitting, working or doing nothing. I think a lot of manufacturers don't give enough thought to their sheaths. Comfort, concealability, accessibility, and securely retaining the knife all have to come together. A simple sheath like the Izula and BK14 have can be user modified to carry the knife in a lot of different positions & locations. That's important. In most cases, I think you just have to try a few different carry locations, knife lengths, etc. to see what works for you.
I carry a small FB 5 or 6 days a week. I stick with knives that are around 7" OAL with a 2.75"- 3" blade length. Most of mine are horizontal carry. The BRKT Essentials are in an angled cross-draw sheath. My favorites are a couple of Doziers (Arkansas Traveler and Straight Personal), Bradford's Guardian 3, and BRKT's Essential. All have well-designed carry systems that are comfortable and easy to reach. I like to carry FBs in cross-draw so I can reach them with either hand. These all work well at about 10:00.
Whereabouts in southwestern VA? ... if I read that right...
