Is It Legal to Carry a Knife in Oregon? Concealed Rules and Penalties

Oregon knife laws allow you to openly carry nearly any knife, but concealing certain weapon-type knives on your person is a Class B misdemeanor unless you hold a valid concealed handgun license. Separate rules ban weapons in courthouses, public buildings, and major airports, and some cities, Portland in particular, add their own limits that state law does not override.1Oregon State Legislature. Oregon Code 166.240 – Carrying of Concealed Weapons

Open Carry Is Broad; Concealed Carry Is Where the Law Bites

Carrying a knife openly is legal in Oregon for virtually every type, including large fixed-blade knives, machetes, and swords. The restrictions kick in once a knife is hidden from ordinary view.

A knife is generally treated as concealed when it is not readily identifiable as a weapon, or when you have made some effort to hide the fact you are carrying it. A folding knife clipped to your pocket with the clip and the top of the handle showing is usually considered openly carried. Drop that same knife fully into the pocket and it reads as concealed. The distinction is small on the sidewalk but decisive in court.

Vehicles count too. A restricted knife tucked into the center console or glove box within arm’s reach can be treated as concealed on your person. If you need to transport one, a locked case or the trunk is the safer choice.

Knives You Cannot Carry Concealed

Oregon does not ban owning these knives. The concealed-carry prohibition under ORS 166.240 targets specific designs:1Oregon State Legislature. Oregon Code 166.240 – Carrying of Concealed Weapons

  • Knives that deploy by the force of a spring or by centrifugal force — switchblades, automatics, and butterfly knives (balisongs).
  • Dirks and daggers, meaning double-edged knives built primarily for stabbing.
  • Ice picks.
  • Similar instruments capable of inflicting injury, under a catch-all that gives courts some discretion.

Notice what is absent: no blade-length limit. A folding knife with a five-inch blade can be carried concealed under state law, as long as it is not spring- or centrifugal-force operated and is not a dagger pattern. Mechanism and design, not size, drive the rule.

Assisted-opening knives sit in a gray zone. These have a small spring that finishes the opening motion once you start the blade manually. Oregon courts have read the statute’s “force of a spring” language broadly enough to reach them, so they may fall under the concealment ban. That differs from federal law, which explicitly excludes assisted-opening knives from the switchblade definition.2Office of the Law Revision Counsel. 15 US Code 1244 – Exceptions For Oregon purposes, treat an assisted opener as restricted for concealed carry.

The Concealed Handgun License Exemption

If you hold a valid Oregon concealed handgun license, the concealed-knife prohibition in ORS 166.240 does not apply to you. A CHL holder can legally carry a concealed switchblade, dagger, or butterfly knife that would otherwise land anyone else in misdemeanor territory.3Oregon State Legislature. Oregon Revised Statutes Chapter 166

The exemption is narrow. It covers concealed carry on the street, nothing else. A CHL does not let you bring a knife into a courthouse, a public building where weapons are banned, or any other restricted location. Peace officers serving process or making arrests have their own blanket exemption from the concealed-carry rule.1Oregon State Legislature. Oregon Code 166.240 – Carrying of Concealed Weapons

Places Knives Are Banned Regardless of How You Carry

Some locations are off-limits whether the knife is open or concealed, and whether you hold a CHL or not. Bringing a knife that qualifies as a “weapon” into any of these places is a Class C felony:4Oregon Public Law. Oregon Code 166.370 – Possession of Firearm or Dangerous Weapon in Public Building or Court Facility

  • Public buildings, meaning government-owned or occupied buildings where public business is conducted.
  • Court facilities, under a stricter subsection. If you bring a non-firearm weapon into a court facility, you may be ordered to surrender it or immediately remove it, and refusing is itself a Class C felony.
  • School grounds, subject to district policies under ORS 166.377.
  • The passenger terminal of any airport with over one million annual boardings.

The Pocketknife Carve-Out

Ordinary pocketknives with blades under four inches are excluded from the definition of “weapon” under the public-building statute, so carrying a small folder into a government office is not automatically a felony.5Oregon State Legislature. Oregon Revised Statutes Chapter 166 – Section 166.360 The carve-out does not reach court facilities, where the rules are tighter and security screening will catch it anyway. For purposes of this statute, “weapon” otherwise includes dirks, daggers, ice picks, metal knuckles, and any knife beyond the under-four-inch pocketknife that could inflict injury. A fixed-blade hunting knife on your belt will qualify.

Portland and Other Local Rules

Oregon preempts local firearm regulation, but that preemption does not extend to knives. Cities and counties set their own rules, and Portland’s go well past state law in specific places.

In Portland parks, you may not possess any knife with a blade longer than 3.5 inches, any knife that deploys by spring or centrifugal force, or any dirk, dagger, or ice pick.6Portland.gov. Portland City Code 20.12.050 – Possession of Weapons On the Portland Streetcar, you cannot bring any knife onto a vehicle or into a station unless it is a folding knife with a blade under 3.5 inches.7Portland.gov. Portland City Code 14A.110.280 – Weapons

These are location rules, not a citywide ban, but they catch people who assumed state law was the whole picture. A four-inch folder that is fine on a Portland sidewalk is a violation in a city park. Other jurisdictions may have their own ordinances, so a quick check of local code before carrying is worth the time.

If You Have a Felony Conviction

Anyone convicted of a felony under Oregon, another state’s, or federal law faces a permanent possession ban that reaches further than the general concealed-carry rule. A person with a felony record cannot own or possess:8Oregon State Legislature. Oregon Code 166.270 – Possession of Weapons by Certain Felons

  • Any knife that deploys by spring or centrifugal force, including switchblades, automatics, and butterfly knives.
  • Dirks, daggers, and stilettos.

This is a possession ban, not a carry ban. These knives cannot be kept at home, carried openly, or carried concealed. Violation is a Class A misdemeanor. Ordinary folding knives and non-dagger fixed blades remain permissible. The restriction can lift if the court declared the conviction a misdemeanor at judgment or the record has been expunged.

Federal Transport Across State Lines

The federal Switchblade Knife Act prohibits shipping or transporting switchblades in interstate commerce, with limited exceptions. Assisted-opening knives with a bias toward closure are explicitly excluded from the federal switchblade definition, but that federal exclusion does not change Oregon’s state-level treatment of them.2Office of the Law Revision Counsel. 15 US Code 1244 – Exceptions A knife legal to ship under federal law can still be restricted from concealed carry in Oregon.

Penalties

Oregon’s knife penalties fall into three tiers:

The jump from misdemeanor to felony is the thing most people miss. A concealed switchblade on a city sidewalk is a misdemeanor. The same knife walked through a county courthouse door is a felony with potential prison time and the lasting consequences a felony conviction brings.
