Pocket knives are generally legal to own and carry in Maryland, with “penknives” explicitly exempted from weapon definitions. Restrictions focus on concealed carry of dangerous weapons and intent, varying by type and location.
Key Definitions and Exemptions
Under Maryland Criminal Law § 4-101(a)(5), a “weapon” includes dirk knives, bowie knives, switchblades, star knives, razors, and other dangerous articles—but excludes “a penknife without a switchblade.” Courts define penknives broadly as any folding knife with the blade folding into the handle, regardless of size (Bacon v. State, 1991).
Common pocketknives like manual folders qualify as penknives, legal for concealed or open carry without restrictions. No statewide blade length limits apply to these.
Carry Regulations
§ 4-101(c)(1) prohibits concealed carry of a dangerous weapon; penknives are exempt, so pocket carry is fine. Open carry of non-penknives (e.g., fixed blades) is legal absent intent to injure (§ 4-101(c)(2)).
Switchblades are weapons: concealed carry banned without a permit; sales prohibited (misdemeanor). Balisongs and OTFs often qualify as penknives if not automatic.
Intent matters: carrying for self-defense risks “purpose of injuring” charges, judged case-by-case.
Location and Special Restrictions
No knives on school property (§ 4-102), even legal ones—misdemeanor up to 3 years/$1,000. Minors in certain counties can’t carry dangerous weapons at night outside hunting.
No statewide preemption: Baltimore limits blades to 3 inches in some areas; check locals. Government buildings often ban all blades.
Penalties and Enforcement
Violations are misdemeanors: up to 3 years/$1,000; higher if intent to injure. Felonies arise if used in crimes.
Police discretion applies; harmless pocketknives rarely issue. Authentication via case law protects folders.
