In Massachusetts, knife laws regulate the ownership, carrying, and use of various types of knives to maintain safety and order. These laws delineate the types of knives that are legal and illegal, as well as the rules for carrying knives, either openly or concealed. The laws also specify certain restricted locations where carrying knives is prohibited, and they provide exceptions for members of law enforcement or the military. Understanding these regulations is crucial to avoid any legal consequences that come with the violation of these laws.

Types of Knives

Legal Knives

In Massachusetts, the following types of knives are generally considered legal to own and possess:

Illegal Knives

Certain types of knives are considered illegal to own, carry, or use in Massachusetts, including:

Carrying Laws

Open Carry

Open carry of knives in Massachusetts is generally permitted for knives that are legal to own. However, the open carry of large knives and blades in public places can potentially be seen as a breach of the peace, or as a threat, especially if carried in a manner that suggests an intention to use the knife as a weapon.

Concealed Carry

Concealed carry laws in Massachusetts are a bit stricter compared to open carry laws. Carrying a knife concealed upon one’s person is generally considered illegal, particularly if the knife falls under the category of being a “dangerous weapon,” or if the individual intends to use the knife unlawfully against another person.

Restricted Locations

In Massachusetts, there are several locations where carrying knives is strictly prohibited, including:

  1. Schools and educational institutions.
  2. Government buildings and courthouses.
  3. Airports and other transportation hubs.

Law Enforcement or Military Exceptions

Members of law enforcement and the military are usually exempt from many of the restrictions imposed on the general public regarding knife possession and carry. These individuals are often allowed to carry weapons, including knives, that are necessary for the performance of their official duties.

Consequences of Law Violation

Violating knife laws in Massachusetts can result in serious consequences, including:

  1. Criminal charges, which can range from misdemeanors to felonies depending on the severity of the violation.
  2. Fines and penalties, which can be substantial.
  3. Possible imprisonment, particularly for serious offenses or repeat violations.


In Massachusetts, knife laws are implemented to ensure public safety and order. It is crucial for residents and visitors to be aware of and comply with these laws to avoid potential legal repercussions. Those who are unsure about the legality of a specific type of knife or manner of carry should consult with legal professionals or relevant local authorities to obtain accurate and up-to-date information.
