In Maryland, pocket knives-specifically defined as “penknives”-are generally legal to own, possess, and carry, either openly or concealed. The law defines a penknife as any knife with a blade that folds into the handle, which covers most ordinary pocket knives.
Open and Concealed Carry
- Open Carry: You may openly carry a pocket knife (penknife) in Maryland. Other knives that do not meet the penknife definition can also be carried openly, provided you do not have unlawful intent (such as using it as a weapon or to deter an aggressor).
- Concealed Carry: Concealed carry of folding pocket knives that are not switchblades or spring-activated is allowed. However, carrying any knife with the intent to use it as a weapon-even for self-defense-can be considered unlawful.
Restrictions and Prohibited Actions
- Switchblades and Ballistic Knives: It is illegal to sell, barter, or offer to sell switchblade knives or ballistic knives in Maryland. However, mere possession or open carry of these knives is not explicitly prohibited by state law, though local ordinances (such as in Baltimore) may impose stricter rules.
- Intent Matters: Carrying a knife for the purpose of injuring someone or for self-defense is considered unlawful intent and can result in criminal charges.
- Schools: Knives, including pocket knives, are strictly prohibited on public school property.
- Minors: In certain counties, minors may not carry a dangerous weapon (including knives) between one hour after sunset and one hour before sunrise, except during legitimate activities like hunting.
Local Variations
Maryland does not have statewide preemption for knife laws, meaning cities and counties can enact stricter regulations. For example, Baltimore has specific restrictions on switchblades. Always check local ordinances before carrying a knife in a new area.
Blade Length
There is no statewide restriction on blade length for pocket knives, but some local jurisdictions may have their own limits. Always verify local regulations if you are unsure.
