This is a very good question.....
When im "out" it is either urban, or the woods, and I carry much different when im in urban then I do the woods.
When I carry in urban environment, I carry for worst case scenerio. Those knives are meant to pry and be built like tanks, but are small, so they dont attract attention and are easily concealed, I carry a folder and fixed blade.
In the woods, I carry for cutting first, wood work, carving, making traps, food prep (cleaning game) fire prep etc. I also carry a GB wildlife hatchet. with a Koster Bushcraft and a wildlife hatchet, there is nothing I cannot do or make in the woods, feel VERY comfortable with this combo, I use to be of the BIG CHOPPER crew, but started to realize this wasnt needed for me, as I didnt chop as much as I cut when in the woods.
