here in holland it isn't TOO bad, atleast on paper. On paper you are allowed to carry any folder locking or not with blade lenght up to 9 cm IF the width halfway on the blade is more than 14mm, if it is't 14 mm up to 7 CM. You are allowed to carry them almost everywhere, except on public places, alcoholic serving places and places where a knife has no usses, but to harm someone, this is judged by the police officer and since knife tolleration is pretty low in this sociaty, you really have to give a good explanetion wenn having a knife on you...
