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).
