I chose bushcraft and neck knives. I picked "bushcraft" for the general shape and all-around utilitarian capabilities, and "neck" for the size. I've found that smaller FBs are the most useful of all knives for me to carry. By smaller, I mean a 2 1/2" to 3 1/4" blade and a 3 3/4" to 4" handle. I like the overall package to be between 6 1/2" to 7" OAL Flat ground spear points & drop points are my favorite grinds and tips. A fairly straight overall profile and concealability are very high on my list of needs with a small FB. I typically carry a BRKT Northstar EDC (my fav FB) or a BRKT Essential (love the M4 and the OAL). I also use Izulas, BK14s, and an ESEE 4 (my larger FB). I don't care much for "super steels" or high end experimental stuff. I like tried-and-true (1095, 52100, A2, 154CM), although I do like BRKT's M4 & 3V. If I carry a folder, it's almost always a BM 525, BM mini-Bone Collector, a Native 5, or a Para 2. I prefer the blade shapes and tips on the BMs and the Native 5, but the Para 2 is just such a sweet overall package that I overlook the tip and blade shape to carry the knife.
I'm 65 YO and have carried a knife for 60 of those years. I'm a "tool" guy, not a "tactical" user. Never been near a knife fight and it's not on my list of things to do. I like the light weight and maneuverability of smaller knives and the strength and dependability of FBs. Pocket sheaths and 45 deg or horizontal carry cross draw sheaths are my choice for carrying.
I do like handmade knives. I have several from Alan Davis and a larger bushcrafter style FB that they call a Green River pattern from the Mathews bros. at Twin Blades in Statesboro GA. I don't "collect" knives, I just buy what I plan to use if it strikes my fancy.
HTH, and thanks for asking us.
