I did not see this posted so thought that I would do so. The below link is a link to a article on Nevada knife laws at both the state and county/municipal local levels. It includes links to the actual laws/ordinances too. I hope that Nevada members and visitors find it useful.

Note that any automatic knife with a blade length under 2" is legal.
