A friend of mine will be visiting Las Vegas later this month and I want to order two Spyderco paramilitary knives and have them delivered to his hotel so that he can bring them back with him. I understand Las Vegas has a knife carry law which restricts you from carrying >3 blades. I just want to know if it will be OK for him to have the knives in his luggage while travelling to the airport and will he be able to keep the knives in his check-in baggage?
