No, throwing stars (shuriken) are classified as dangerous weapons under Massachusetts General Laws Chapter 269, Section 10(b), making their possession or use unlawful without proper authorization. Local law enforcement agencies, including the Massachusetts State Police, actively enforce these restrictions, particularly in urban centers like Boston where blade-related incidents have prompted heightened scrutiny. Recent 2026 legislative proposals aim to further restrict “ninja weapons,” potentially expanding prohibited items to include modified shuriken designs.
Key Regulations for Throwing Stars (Shuriken) in Massachusetts
- Prohibited Possession: Under MGL c. 269 § 10(b), shuriken are explicitly listed as “dangerous knives,” barring ownership without a valid firearms license or law enforcement exemption.
- Use in Public Spaces: Displaying, carrying, or throwing shuriken in public—even for self-defense—violates MGL c. 269 § 10(j), with penalties including fines up to $1,000 and imprisonment for up to 2.5 years.
- Antique Exceptions: Shuriken manufactured before 1900 may be possessed if registered with the Massachusetts Historical Commission, but modern reproductions fall under strict prohibitions enforced by the Executive Office of Public Safety and Security.
