Few things that are done by regulation, rule, "the book" are allowed to be reasonable. To be reasonable one must be both intelligent and flexible. Due to the need to higher thousands of security screeners quickly, intelligence is not a given. Due to the need for consistancy in enforcement in order to reduce litigation costs flexibility is not allowed. By the book, Flashlights are allowed. By the book, weapons are not allowed. Properly describe your items sir? There was a discussion on EDC knives earlier that OldBaldGuy weighed in on on this exact topic. If you have a jacknife in your pocket to spread your peanut butter you don't have a concealed weapon - even if it is a custom one hand opener. If it has serrations it must be for cutting your seat-belt after you car went into the surf. If you admit that you carry it for self defense you are a new class of dangerous criminal carrying a concealed weapon. That is just for dealing with getting a ticket on the freeway!

If I have mis-rememberd the old thread or attributed things incorrectly to OBG I apologize.
