A few years ago I visited a friend who was working for a TLA. In his office I saw him stabbing at packing boxes with a ball point pen trying to cut the tape.
I walked over to him and handed him my swiss army knife. His eyes got wide "you can't have that in this building!"
What? A swiss army knife? I have been carrying a swiss army knife since I was 8 years old.
Guess I am violating federal law by packing a weapon of mass destruction to work.
This is the one I carry every day

I have others that I carry for other occasions.
