Oregon maintains relatively permissive knife laws focused on concealed carry restrictions rather than outright bans or blade length limits for pocket knives. Ordinary pocket knives are legal to own and openly carry statewide, with exceptions for specific types like switchblades when concealed. State preemption does not exist, allowing local variations, while felons face stricter prohibitions on certain blades.
Ownership Rights
Most pocket knives, including folding and assisted-opening models, can be owned by non-felons without restriction on blade length. Felons under ORS 166.270 cannot possess knives with blades that project by spring or centrifugal force, such as switchblades or OTF knives. No statewide registry or purchase permits apply to pocket knives.
Concealed Carry Rules
ORS 166.240 prohibits concealed carry of knives with blades that open via spring or centrifugal force, including switchblades, butterfly knives, and OTFs, plus dirks, daggers, and ice picks. Ordinary pocket knives—typically folding blades under 4 inches—are exempt and legal to conceal. Open carry avoids these issues entirely for all lawful knives.
Public Building Limits
ORS 166.370 bans dangerous weapons, including non-ordinary knives, in public buildings and courts, but permits ordinary pocket knives with blades less than 4 inches. Schools prohibit all knives under broader weapons laws. Intent matters: any knife used threateningly becomes a “dangerous weapon” under ORS 161.015.
Local Variations
Cities like Portland may impose tighter rules, such as blade length caps or additional carry bans, overriding state allowances. Rural areas generally follow state law. Travelers should verify municipal codes before carrying.
Penalties and Defenses
Violations of concealed carry rules constitute Class A misdemeanors: up to 1 year jail and $6,250 fines. Public building possession escalates to Class C felonies: up to 5 years prison and $125,000 fines. Affirmative defenses include lawful self-defense or sporting use.
Practical Guidance
Measure blades tip-to-hilt; opt for under-4-inch folders for versatility. Avoid prohibited types concealed; display openly if needed. Consult Oregon State Police or attorneys for personalized advice amid local nuances.
