Maryland’s Knife Laws (2026)

Yes, ownership is legal, but concealed carry of switchblades is prohibited.

Yes, if it’s a non-switchblade folding knife. Maryland § 4-101 excludes a “penknife without a switchblade” from the dangerous-weapon definition, regardless of blade length or locking mechanism.

Concealed carry of dangerous knife like dirk, bowie, switchblade, or star knife is illegal. Open carry is unlawful only when done with intent to injure another person unlawfully.

Maryland law does not specify a statewide blade-length restriction, but context and intent matter.

If it's a switchblade, you face serious charges. A first offense is a misdemeanor: up to 12 months in jail, a $1,000 fine, or both. Non-switchblade folders remain legal under the statewide penknife exemption.

Yes, in 12 specific counties only. In Anne Arundel, Baltimore, Caroline, Cecil, Harford, Kent, Montgomery, Prince George's, St. Mary's, Talbot, Washington, and Worcester counties, minors cannot carry a dangerous weapon between one hour after sunset and one hour before sunrise.

No, carrying knives in schools, courthouses, and government buildings is prohibited.

Yes, in checked baggage only. TSA prohibits all knives in carry-on baggage and the secure area beyond the checkpoint. Pack knives in your checked bag, sheathed or securely wrapped to protect baggage handlers. This federal rule applies to all travelers at Maryland airports.

A penknife is any folding knife opened by manual hand action only, regardless of size or locking mechanism. A switchblade opens automatically when you press a button or spring in the handle, requiring no manual deployment.
