Nebraska Knife Laws & Legal Carry Explained

Nebraska’s knife laws underwent significant revisions in 2023 after decades of stability. Recent updates mean that regulations from several years ago may no longer be accurate, and some current rules are subject to ongoing legal challenges.

The blade-length threshold that defines the legal treatment of knives has been in place for years. However, recent legislation has altered the rules on who may carry a knife, where carry is permitted, and the authority local governments hold.

Nebraska law outlines specific criteria for knife ownership, restrictions for certain groups, potential penalties, and ongoing legal disputes as of early 2026.

Nebraska’s Current Knife Carry Framework

• Any knife with a blade longer than 3.5 inches is classified as a deadly weapon under Nebraska statute §28-1201.

• Since September 10, 2023, adults who are not prohibited persons can legally carry concealed knives, including those over 3.5 inches, without a permit.

• Minors and prohibited persons still face criminal penalties for concealed carry of knives.

• Nebraska does not ban switchblades, automatics, or other specific knife types at the state level.

• A state preemption law nullified local weapons ordinances, but the cities of Lincoln and Omaha have challenged it in court.

• Both city-level legal disputes remain in active litigation as of early 2026.

• Weapons, including knives, are still restricted in sensitive locations like schools, courthouses, and polling places.

The 3.5-Inch Rule

A 3.5-inch blade length serves as the legal threshold in Nebraska. Under §28-1201, any knife with a blade exceeding 3.5 inches is classified as a deadly weapon. This applies to daggers, dirks, knives, and stilettos. If a knife's blade is longer than 3.5 inches, its classification as a deadly weapon is automatic under state law, regardless of intended use.

The Nebraska Supreme Court reinforced this reading in State v. Nguyen, decided in 2016. In that case, law enforcement stopped the defendant and searched his vehicle, finding methamphetamine and a stiletto knife with a blade measuring 3.75 inches. The court held that the knife qualified as a deadly weapon per se, and the manner or intended use was not an element the prosecution needed to establish.

That does not mean knives with blades measuring 3.5 inches or less are always treated as harmless tools. State v. Bottolfson, decided in 2000, addressed this gap. The court ruled that when a case involves an instrument not specifically named in the statute, the prosecution must prove the instrument is a dangerous instrument capable of inflicting cutting, stabbing, or tearing wounds.

A smaller knife may still result in legal consequences, depending on its use and the authorities’ interpretation of the circumstances.

What LB 77 Changed

Before September 2023, carrying a concealed knife in Nebraska was a criminal act. The law prohibited the concealed carry of knives, brass knuckles, and other dangerous weapons, without distinction between blade length or knife type.

Governor Jim Pillen signed LB 77 into law, and it took effect on September 10, 2023. The bill allows Nebraska residents to conceal a firearm, knife, or other legal weapon in their clothing or vehicles without a government permit or safety training. This applies to any adult who is not a prohibited person under federal law.

LB 77 also introduced a stronger preemption provision. Local weapons ordinances of all kinds, including those covering weapons other than firearms, were rendered null and void. The statute was later updated by LB 1329 in 2024, which refined certain provisions.

Adults without felony convictions, active protection orders, or other disqualifying conditions may carry concealed knives in Nebraska without a permit or paperwork.

Who Cannot Carry

The concealed carry allowance under LB 77 does not apply to everyone. 2 groups remain restricted.

Minors may not carry a weapon or any concealed weapons on or about their person. This includes handguns, knives, brass or iron knuckles, and any other deadly weapon.

Prohibited persons face the same restriction, and the consequences are steeper. Under §28-1206, a person is a prohibited person if they:

• Have a prior felony conviction

• Are a fugitive from justice

• Are the subject of a current and valid protection order

• Are on probation under a deferred judgment for a felony

Penalties by Offense

Knife Types Allowed in Nebraska

Nebraska does not ban specific knife types at the state level. You can legally own and carry a switchblade, an automatic knife, a gravity knife, a fixed blade, a folding knife, a dagger, or a stiletto.

The American Knife and Tool Institute’s state-by-state breakdown notes that any knife type with a blade longer than 3.5 inches falls under the deadly weapon classification. However, there is no outright prohibition on adults who are not legally prohibited from possessing or carrying these knives.

The one federal-level exception applies to ballistic knives, which remain restricted in interstate commerce under federal law. You are unlikely to encounter this in practice, but it exists.

Here is a quick reference:

• Switchblades and automatic knives: Legal to own and carry

• Fixed blade knives: Legal to own and carry

• Folding knives: Legal to own and carry

• Daggers and stilettos: Legal to own and carry

• Gravity knives: Legal to own and carry

• Ballistic knives: Restricted under federal law in interstate commerce

Where You Still Cannot Carry

Even with LB 77 in place, Nebraska restricts the possession of weapons in certain sensitive locations. Knives and other weapons remain prohibited in:

• Schools and school grounds

• Courthouses

• Detention facilities

• Polling places on election days

These restrictions are outlined in LB 77, the Concealed Handgun Permit Act. Carrying a knife into one of these locations can result in criminal charges regardless of your age or legal status.

The Lincoln and Omaha Legal Fights

LB 77’s preemption clause was supposed to settle the question of local authority over weapons regulations. It did not. After the law took effect, the mayors of both Lincoln and Omaha issued executive orders restricting the possession of weapons on city property.

Lincoln’s position went further than Omaha’s. City officials claimed the authority to prohibit the public possession of all dangerous weapons on city grounds, including firearms and knives. Omaha’s executive order similarly restricted weapons on city property but with a narrower scope.

On December 15, 2023, Nebraska Attorney General Mike Hilgers issued a formal opinion stating that both executive orders were illegal under LB 77’s preemption language.

In Omaha, a Douglas County judge issued a temporary injunction halting enforcement of the mayor’s executive order, finding that it was preempted by LB 77. In Lincoln, the dispute reached the Nebraska Supreme Court.

In August 2025, the court ruled that even though the Lincoln ordinance had not yet been enforced, four individual gun owners had standing to challenge it because a “credible threat” of harm existed. The court sent the case back for further proceedings on the merits.

As of early 2026, both cases are still in litigation. Enforcement of local weapons restrictions on city property in Lincoln and Omaha varies, so those carrying knives in these cities should stay up to date on current court rulings.

What This Means If You Carry a Knife in Nebraska

The core rules are straightforward if you are a legal adult with no disqualifying record. You can carry a concealed knife of any type, including blades over 3.5 inches, without a permit anywhere in the state outside of restricted locations. You do not need a safety class. You do not need government paperwork.

If you are a minor or a prohibited person, the old restrictions still apply, and the penalties are real. A first offense is a misdemeanor. A second offense is a felony. And possession of a deadly weapon by a prohibited person carries up to four years in prison.

Keep in mind that a knife with a blade over 3.5 inches is treated as a deadly weapon under the statute, regardless of your intent. If you are involved in any legal situation while carrying one, the classification is automatic.

The Lincoln and Omaha disputes add a layer of uncertainty for anyone who regularly visits city-owned buildings or property in those municipalities. Until those cases are fully resolved, the safest approach is to monitor the court proceedings and exercise caution when carrying on city grounds in either location.
