What is the maximum blade length of a knife an average (read: non-military, non-badass) person can carry before it becomes obvious that the guy is trying to compensate for his lack of badassery with a huge knife? Obviously if you're clearing brush, carrying a machete is no big deal. But if you're hiking a well traveled route, such as the Appalachian Trail, with no threatening large animals, I say 6-7" blade length is about the max. Any opinions?
