Me and my Grandmother are going on a trip to Australia for 3 days, then flying to New Zealand for 4 more days. Be cause I will be in foreign countries I would like to bring something to defend myself. I would like to know the restrictions kn knives for both areas. I have my knife I have for personal use that has a 5 1/2 inch blade, which I doubt I can bring and can't even carry in Tennessee, but I have been looking at a Karambit that is 4 inches long, which I can carry here, and I was wondering if I can bring and carry it with me to these places aswell, and if not what kind of knife should I look into for self protection.
