Katanas are generally legal to own in New Jersey, but the 2026 Blade Laws place strict limits on how they can be carried, displayed, or transported. Possession for collection, sport, or decorative purposes is allowed without a permit, yet public carry with intent to use as a weapon is prohibited unless a valid weapons permit is issued. Violations can result in misdemeanor charges, fines, and possible seizure of the weapon.
Overview of the 2026 Blade Statute
The 2026 amendment to NJ Statutes § 2C:39‑1 redefined “dangerous weapon” to include any blade longer than 6 inches that is designed for combat. The law created three categories: prohibited weapons, restricted weapons, and ordinary knives. Katanas fall under the restricted weapons class because they are traditionally forged for combat and exceed the length threshold. Ownership remains lawful, but the statute requires that they be stored in a locked container when not in a private residence.
Specific Provisions for Katana‑type Swords
- Length and design – Any sword with a blade over 6 inches that possesses a curved single‑edge profile is automatically classified as a restricted weapon.
- Transportation – When moving a katana, it must be placed in a hard‑shell case, locked, and transported in the trunk of a vehicle. Carrying it on one’s person outside the home is a violation unless a permit is present.
- Display – Public exhibitions, museums, and trade shows are exempt, provided the sword is displayed on a secure mount or within a case.
These provisions were added to address rising incidents involving imported swords used in assaults, as reported by the New Jersey State Police in 2025.
Permits, Exemptions, and Enforcement
A valid Permit to Carry a Dangerous Weapon (PCDW) can be obtained from the County Prosecutor’s Office after background checks, training, and a demonstration of a legitimate need, such as participation in martial‑arts competitions. Exemptions apply to law‑enforcement officers, military personnel on duty, and registered collectors who store their swords in a home safe. Police officers are instructed to verify the presence of a permit before seizing a katana, but they may still confiscate it if they suspect intent to harm.
