In this section, our attorneys explain Nevada’s criminal laws and legal concepts, A to Z
No, butterfly knives are generally legal under Nevada knife laws.
However, people who take a butterfly knife with a blade of at least two (2) inches long to a school may face criminal charges if they are also trespassing, loitering, causing a nuisance, or defacing school property.
And any pupils who take any butterfly knife to school face expulsion, even if they cause no other trouble.
As its name suggests, a butterfly knife is a folding pocketknife except that the blade is concealed by not one but two handles. When the knife is open, the two handles join to become one large handle.
Other names for butterfly knives are:
Butterfly knives are not considered a switchblade under Nevada law.
It is legal to open carry butterfly knives in Nevada. But as discussed below, they may be prohibited at schools under certain conditions.
Nevada law is unclear about whether it is illegal to carry a butterfly knife concealed.
The CCW statute NRS 202.350 only says it is illegal to conceal carry a “dangerous or deadly weapon.” None of the other statutes in NRS chapter 202 mention butterfly knives as a dangerous or deadly weapon. But an entirely separate statute in a totally different chapter — NRS 392.466 — defines butterfly knives as a “dangerous weapon.”
If a butterfly knife is a dangerous or deadly weapon, carrying one concealed without a CCW permit is a category C felony in Nevada. The penalty is:
People are advised to contact their local sheriff to inquire whether they need a CCW permit in order to carry a butterfly knife. Every city and county has its own weapons laws. For instance, people in Clark County need a CCW permit in order to carry concealed a knife with a blade that measures at least three (3) inches. Violating this rule is a misdemeanor, carrying:
NRS 393.410 makes it a gross misdemeanor to do any of the following while in possession of a butterfly knife with a blade of two (2) inches or longer:
The penalty in Nevada is:
In addition, people face prosecution for a “public offense” if they have butterfly knife with a blade of two inches or longer while “willfully and maliciously injuring, marking, or defacing any public schoolhouse, its fixtures, books, or appurtenances.” The punishment depends on how much damage the defendant allegedly caused.
The defendant will be prosecuted for a misdemeanor in Nevada if the property damage totals less than $250. The sentence is:
The defendant will be prosecuted for a gross misdemeanor in Nevada if the property damage totals at least $250 but less than $5,000. The sentence is:
The defendant will be prosecuted for a category C felony in Nevada if the property damage totals at least $5,000 or higher. The sentence is:
And pupils who bring butterfly knives to school face expulsion. It makes no difference what length the blade is or whether the pupil planned to harm anything or anyone. A first offense of bringing a butterfly knife to school carries an expulsion sentence of one year. A second offense carries permanent expulsion.
