Nebraska Knife Laws
Nebraska’s number is three and a half inches. Any dagger, dirk, knife or stiletto with a blade over that may not be carried concealed. Automatic knives have never been restricted, so the same three and a half inch line is what applies to them. There is no statewide preemption, and Omaha and Lincoln may set their own rules.
This is not legal advice, and we are not lawyers. It is a plain reading of published summaries and the statutes they cite, kept current on a fixed schedule. Local ordinances are frequently stricter than state law and are not all captured here. Check the statute, and check your city, before you carry.

How fresh this is, and how you can tell
Two dates sit above, and they are not the same thing. Checked by us is the last time a person went back to the sources and confirmed this page still matches them. Source last revised is when the American Knife and Tool Institute last updated its own Nebraska page. A 2021 revision date is not automatically wrong — it usually means nothing has changed since — but it does mean nobody had looked recently, and that is exactly the gap this page exists to close.
Crossing the Nebraska state line
Knife law stops at the border and the next state does not have to agree with this one. If you drive, these are the states you are most likely to carry into, and what changes when you do.
| State | Automatic knives | Concealed blade limit |
|---|---|---|
| South Dakota | Legal | No state blade length governs; concealed carry is lawful unless you carry with intent to commit a felony. The city rule is what is likely to catch you. |
| Iowa | Legal | Five inches. A dagger, razor, stiletto, switchblade or any knife with a blade over five inches is a dangerous weapon and may not be carried concealed. |
| Missouri | Legal | Four inches. An ordinary pocketknife at or under four inches goes almost anywhere concealed. Any other blade is barred from seventeen listed places, and a concealed carry permit lifts those place limits. |
| Kansas | Legal | No blade length governs. You may carry a knife concealed or not, at any length. |
| Colorado | Legal with conditions | Carrying a concealed knife with a blade over three and a half inches is a violation. |
| Wyoming | Legal | No blade length governs, and open carry is unrestricted. The concealed deadly weapon rule carries exceptions from 21 for people without violent crime or drug convictions. |
A knife that is lawful in your pocket at home can be unlawful the moment you cross, and nobody stops you at the line to tell you. The map for all fifty states covers the rest.
Common questions about Nebraska knife laws
What size knife is legal to carry in Nebraska?
Three and a half inches. Any dagger, dirk, knife or stiletto with a blade over three and a half inches may not be carried concealed.
Are switchblades legal in Nebraska?
Legal. No restriction has ever been enacted, so the three and a half inch concealed limit is what applies.
Which knives are banned outright in Nebraska?
None outright.
Does Nebraska have knife preemption?
No. Nebraska has no statewide preemption, so a city or county can be stricter than the state code, and several are. Check your local ordinance as well as the statute.
Can I keep a knife in my car in Nebraska?
Where a state has a concealed carry limit, a knife in a glovebox or a door pocket is generally treated as concealed. Read the concealed line above and apply it to the vehicle. If that line says concealment is not the issue in this state, the vehicle is not the issue either — but where you drive to still is, because schools and courthouses are barred everywhere.
Where this comes from
Two independent sources, cross-checked against each other, and the statute text where they disagree. The automatic knife column is the American Knife and Tool Institute’s state automatics table, checked against Knife Rights’ own switchblade legality table and their legislative update log. Everything on a state page is quoted or closely tracked from that state’s AKTI page, and we print the date AKTI last revised it so you can see for yourself how fresh the underlying work is.
Where a source is older than a change we know about, we say so on the page rather than quietly leaving the old answer up. That is the whole reason this is checked every two months.
