- Folding pocket knives (“penknives”) are legal to own, possess, and carry in Maryland, both openly and concealed, as long as they are not switchblades or spring-activated knives. A “penknife” is defined as any knife with a blade that folds into the handle.
- There are no statewide blade length restrictions for pocket knives under Maryland law, though some local ordinances (such as in Baltimore) may impose additional rules.
Concealed and Open Carry
- Concealed carry of ordinary folding pocket knives (not switchblades or spring-assisted) is generally permitted.
- Open carry is also allowed for these knives, provided you do not carry them with the intent to harm or use them unlawfully.
- Carrying any knife (other than a penknife) with the intent to use it as a weapon, or to deter an aggressor, is considered unlawful intent and can lead to criminal charges.
Prohibited Knives
- Switchblades, gravity knives, and automatic knives are generally prohibited from concealed carry and are subject to restrictions on sale and transfer.
- Open carry of automatic knives may be allowed in some cases, but local ordinances (like in Baltimore) may ban them outright.
Location-Based Restrictions
- Schools: It is illegal to possess any knife on public school property.
- Other restricted areas: Courthouses, airports, government buildings, and certain other locations may have their own prohibitions.
- Minors: In several specified counties, minors may not carry a dangerous weapon (including knives) between one hour after sunset and one hour before sunrise, except when hunting or participating in certain activities.
Intent Matters
- Carrying a pocket knife for general utility purposes is legal. However, if you carry any knife with the intent to use it as a weapon, or for self-defense, it may be considered unlawful and subject to criminal penalties.
- Using a pocket knife for self-defense can lead to prosecution, as Maryland law does not recognize carrying a knife for defensive purposes as a lawful intent.
Local Ordinances
- Maryland does not have statewide preemption, so local jurisdictions can enact stricter knife laws. Always check local city or county rules, especially in Baltimore and Ocean City, which have additional restrictions.
