Nevada law prohibits the open or concealed possession of dirks, daggers, or switchblades in the following children-populated locations: Private or public schools (or vehicles belonging to them); public universities such as UNLV; licensed child care facilities (or vehicles belonging to them). Exceptions to this rule include security guards, peace officers, and other people given written permission to carry the weapon on the premises. And people who run child care facilities in their own homes may have their knives on the premises; however, they should be careful to keep the children away from them or else they could face charges of reckless endangerment (NRS 202.595) or worse.
