Josh,
I lived in NV near Reno for 12 years and had a CCW most of the time. Never had a problem carrying a concealed handgun in a casino. NV laws on concealed knives are no dirks, no daggers,no switch blades.
I never had a problem with folders less than four inches in length. The BM 94X series are pretty sheeple friendly.
The old rule pretty much stands. If you don't pull it out to threaten some one, no one will bother you. If you do need it for self defense then whether the knife was legal or not is the least important thing you have to worry about.
