Think..."US Knife Laws Simplified!" 4.5 / 5 stars. Quickly and easily figure out your situation and feel more confident making potential decisions. Wish there was an international version... Pro-Tip: Almost lost my 20 year old Benchmade 940 (packed in our check in luggage) after landing in Seoul Korea, they are not very EDC friendly, best to leave it at home. Washington DC Federal buildings and ANY/ALL of the Smithsonian's Museum buildings and also the Warner Theatre... KNIVES ARE FORBIDDEN!

needs much more interface development. Overall, it looks like a high school app. It's not reliable at all.
