There isn't anywhere in the world where you can legally carry one I 'm pretty sure. And for that matter damn few places where you can legally carry a concealed handgun. Just my two . YMMV
Huh? According to this, automatics knifes are legal to carry in almost half the states of the union. Here are the states that allow conceal carry permits. The only states where the right to carry is outright denied are American Samoa, Illinois, N. Mariana Islands. If I recall, the Illinois one was just found unconstitutional.
