Maryland Knife Definitions

Before you read about knife laws specific to the state of Maryland, there are essential definitions you should know. Some of these are defined within the law, and some are derived from case laws:

  • Weapon – a weapon includes a dirk, bowie, switchblade, star knife, sand club, metal knuckles, and nunchaku. The law further states that a weapon does not have a handgun or a penknife without a switchblade.
  • Penknife – in the case of Bacon vs. Maryland, the court concluded that a penknife with a manual folding blade is not a weapon regardless of size.
  • A Switchblade knife or switchblade penknife – is a knife with a blade that opens automatically by hand pressure applied to a button, spring, or other devices on the knife’s handle. Another definition of these terms is a device designed to propel a blade from a metal sheath using a high compression ejector spring, also known as a shooting knife. Going by the second definition, a ballistic knife is also considered a weapon under state law.
  • Gravity knife – In Savoy vs. state case, the court concluded that a gravity knife is similar to a switchblade because you open a gravity knife by pressing a button. The only difference is that the blade is suspended through gravity. Therefore, according to the law, a gravity knife is also considered a weapon.
  • Conceal carry – in the case of Shipley vs. state, the court determined that a weapon is concealed if it is situated in a way that is not discernible by ordinary observation by people close enough or in contact with the possessor in the usual associations of life. However, absolute invisibility is not required. From the above definition, it is essential to note the warning that complete invisibility is not required. This makes knives like pocket clips questionable. However, the burden of proof that a weapon is concealed is on the prosecution and not the owner or carrier of the knife.

Maryland Knife Carry Laws

The above definitions will help you understand Maryland’s knife carry laws summarized below:

  • It is against the law to wear or carry concealed any dangerous weapon on or about the person.
  • It is illegal to openly wear or carry a dangerous weapon, tear gas device, chemical, or pepper mace with intent to harm another person or use unlawfully.
  • It is legal to carry a weapon as a reasonable precaution against apprehended danger. It is up to the court to judge whether it was reasonable to have the weapon depending on the occasion and other facts presented in the case’s evidence.
  • It is illegal for a minor to open or conceal carry a dangerous weapon one hour after sunset and one hour before sunrise. According to Maryland state law, a child is anyone under 16 years. This law also applies to several counties within the state, including Anne Arundel, Baltimore, Washington, Worcester, Caroline, Cecil, Harford, Kent, Montgomery, Prince George, Talbot, and St. Mary’s County. A minor can only carry a dangerous weapon during a hunting trip or if they are engaged in or on the way to a military or civic activity like a trap shoot or sport shooting event.
  • It is illegal to carry or possess a knife, firearm, or any deadly weapon on public school property. However, students can use knives lawfully in school-related activities such as food preparation, biology dissection, woodworking, groundskeeping, maintenance, and fake knives for theatrical productions.
