Pocket knives are fully legal to own, openly carry, and conceal in Kansas for adults, with no blade length limits or bans on types like switchblades since 2013 reforms. Statewide preemption prevents local restrictions, making Kansas one of the most permissive states for everyday carry.
Ownership Rules
Adults 18+ can possess any ordinary pocket knife, including folders, assisted-openers, autos, and fixed blades defined as “cutting instruments with sharpened or pointed blades.” No registration or purchase permits required; sales of switchblades legalized post-HB 2033, removing federal-era bans. Minors face no explicit age minimum but can’t use knives criminally; parental discretion applies.
Carry Regulations
Open and concealed carry of pocket knives is unrestricted statewide, per K.S.A. 21-6302 (knives excluded from weapon prohibitions) and AG Opinion 2014-01 confirming any blade length. Switchblades, gravity knives, dirks, daggers, and disguised blades (e.g., sword canes) are permitted openly or concealed. Intent matters: Carry for lawful purposes (EDC, work, hunting) avoids “criminal use of weapons” charges under K.S.A. 21-6301.
Restricted Locations
Knives are banned in K-12 schools, jails, juvenile facilities, and courthouses (K.S.A. 21-6301). Government buildings and private properties with signage may prohibit via policy; universities can ban open carry per AG rulings. No issues in vehicles, bars, or parks absent local rules (preempted since 2013).
Felon Restrictions
Convicted felons can’t possess “daggers, dirks, switchblades, stilettos, or straight-edged razors” under K.S.A. 21-6304; the vague “like character” clause was voided in State v. Harris (2020), protecting ordinary pocket knives under 4 inches. Everyday folders (e.g., 3.5-inch blade) are safe post-ruling, but avoid listed types.
Prohibited Items
Only throwing stars/shurikens and ballistic knives (exploding blades) are outright illegal statewide. Bludgeons, metal knuckles, and slungshots remain banned under concealed weapon laws, but not knives. No blade length caps or assisted-open bans.
Penalties for Violations
Unauthorized possession in restricted areas or criminal use: Class B misdemeanor (up to 6 months jail, $1,000 fine), escalating to felony if during another crime. Felon violations: Level 8 felony (13–17 months prison). Confiscation standard; civil suits rare absent injury.
Historical Changes
Pre-2013, concealed blades over 4 inches and switchblades were restricted; HB 2033 repealed these, enacting K.S.A. 12-16,134 for preemption and full liberalization. No 2026 updates; remains permissive amid national trends.
