Used to, but not anymore.
I used to work in a lumberyard and camped a lot, so I always carried a knife on my belt.
Nowadays, I'm in a cushy office job or on an airplane to visit customers. Too much time on airplanes and too little time to deal with the TSA.
I have a Gerber folder in my glove box just in case... stubborn packaging, etc.
Still bust out the Swiss Army Knife from time to time from my Boy Scout days.
