Not sure about knife laws there. In the middle east, you are probably allowed and even assumed to be carrying a dagger. I'm only half kidding. I think I would be more worried about other forms of contraband that we consider common everyday items such as alcohol, western publications with pictures (magazines, catalogs, advertising fliers), certain religious texts, etc. You might want to check with the state department for a thorough heads-up on knife laws and other relevant issues.
