OK Gary, here we go.
I carry the Emerson Karambit because I am really NOT sure what would happen If I shot someone at work. JUST because they are trying to escape does not mean you can automatically shoot them. With a knife I could claim I TRIED to not use deadly force but when they are within arms reach the tide turns. I think that most reasonable (around here) folks (Jurors) would accept that.
A SECOND folder, cause I don't want folks (potential bad guys) to know I have a "Defensive folder and the will to use it if need be".
The "Bushcraft" blade(s) even though I'm not "Bushy" I do upon occasion have a need for a blade like this, all the way up to a big Ole Choppa!
Whenever I am out in the woods, which isn't really all that much, I usually carry the Wardog, mainly because I like the sheath I have for it better than the one for the S5. The Bigger blades USUALLY stay in the truck until needed.
