Maryland knife laws hinge on Criminal Law § 4-101, distinguishing everyday tools from “dangerous weapons” based on type and intent. Ordinary pocketknives are exempt, but carrying certain blades with intent to harm is a misdemeanor or felony.
Allowed Knives and Carry Rules
Folding knives (penknives without switchblades) are legal for open or concealed carry statewide, regardless of blade length. Assisted-opening knives are permitted as they lack automatic switches.
Open carry is fine for most knives absent unlawful intent; a visible sheathed blade isn’t concealed.
Prohibited and Restricted Knives
Switchblades, gravity knives, bowie knives, dirks, and star knives qualify as dangerous weapons. Concealed carry of these is illegal; open carry requires no intent to injure. Sales of switchblades are banned.
Self-defense intent turns any knife illegal under § 4-101(c)(2).
Key Locations and Exceptions
Knives are banned on K-12 school property, with narrow exceptions for law enforcement or demonstrations. Baltimore City prohibits switchblades outright via local rules.
Minors face curfew restrictions in select counties.
Penalties for Violations
Defenses include lack of intent or lawful purpose.
Practical Advice
Carry folding utility knives openly or in pockets for work/tools. Avoid fixed blades or autos unless justified. Check local ordinances in Baltimore or Montgomery County, and consult MD Criminal Code or an attorney for specifics—no major 2026 changes noted.
