Definitely, but the Spyderco shape is at the least nontraditional. Here I'm basically preparing for the worst in the urban jungle - the possibility that I might have to use it in front of people in power that I have never met before. Basically, I should not hesitate a bit to use it, and traditional-looking knives meet that criteria.
If you think a byrd is still too much, I'm guessing swiss army is your best bet then, it's probaby as non-threating as they come.
