For travelling, I would bring along an opinel no8. Its an unassuming pocket knife and usually customs dont have any issues with it since its just mundane looking. Been to Bali, Sri Lanka, Thailand, UK without any issues. Furthermore if there was any issues with it, I won't be that upset if it was confiscated. Get the version with the inox blade. Cheap and cheerful, however it does not have a pocket clip but it does spot a lanyard fob.
