Knife carry law in New Jersey

New Jersey has no blade-length rule. Switchblades, gravity knives, daggers, dirks and stilettos are possession offences unless you have an explainable lawful purpose. Any other knife that counts as a weapon is an offence when carried under circumstances not manifestly appropriate for lawful use. Context decides outcomes.

This summary rests on mostly official, partly secondary sources. Open questions are listed at the end. Treat anything marked unclear as a reason to leave the item at home.

How we apply the law

Rules are checked from the top. The first one that fits decides. Every verdict on this site comes from this list, not from hand typed cells.

1Reason neededAny knife or tool, automatic
Switchblades (button/spring in handle) are listed in 2C:39-3(e). Possession without an explainable lawful purpose is a fourth-degree crime. Statute is the burden-on-carrier type; courts read 'explainable' narrowly, so carry is high risk.
Source
2Reason neededAny knife or tool, gravity or flick opening
'Gravity knife' means a blade released by gravity or centrifugal force; listed in 2C:39-3(e). Balisongs and flick knives plausibly fall inside. Fourth-degree crime without an explainable lawful purpose. Whether a given balisong qualifies is not settled in sources we read.
Source
3UnclearAny knife or tool, spring assisted
Switchblade is defined as opening 'automatically by hand pressure applied to a button, spring or other device in the handle'. Thumb-stud or flipper assisted knives are arguably outside that, but no authority found either way; 'dangerous knife' catch-all still applies.
Source
4Reason neededA fixed blade, double edged
Double-edged fixed blades fit 'dagger, dirk, stiletto' in 2C:39-3(e). 'Dagger' is not statutorily defined, so a court decides; carrying without an explainable lawful purpose is a fourth-degree crime.
Source
5Reason neededA fixed blade
Not named, but a fixed blade can be a 'weapon' under 2C:39-1 ('other dangerous knives'). Carry is an offence under 2C:39-5(d) if circumstances are not manifestly appropriate (e.g. hunting, fishing, work). Concealed urban carry is risky.
Source
6UnclearA folding knife
No length or lock limit in statute. A pocket folder is an offence only if treated as a weapon carried under circumstances not manifestly appropriate. Practitioners say outcome depends on intent, context, and officer/prosecutor discretion.
Source
7No restriction foundA multitool, a keychain tool or scissors only
No specific restriction found for tools or scissors. They are not named in 2C:39-3(e); general 2C:39-5(d) still applies if used or carried as a weapon.
Source
8UnclearAnything else
Catch-all: New Jersey has no clear safe-harbour for knives. The outcome turns on whether the item is a 'weapon' and on circumstances of carry.

Specifications come from the makers. Where a maker does not publish the cutting edge length, a length rule can only be answered if even the full blade length falls on one side of the line. Otherwise the result is unclear, on purpose.

What the verdict does not cover

Public transport and restricted zones: Not verified for NJ Transit or airports. Federal rules apply at airports (TSA): knives are not allowed in carry-on.
Schools, workplaces and events: 2C:39-5(e)(2): any weapon in 2C:39-1(r)(3)-(4) (includes gravity/switchblade/dagger/dirk and other dangerous knives) or other weapon on school/college grounds without written authorisation is a fourth-degree crime.
In a vehicle: No knife-specific vehicle rule found. 2C:39-5(d) 'not manifestly appropriate' test applies; knives stored in a trunk or tool box are easier to explain than one in the cabin.
Age limits: Not verified: no knife-specific age statute found.
Buying and importing: Not verified. Possessing a switchblade/gravity knife is the offence, so ordering one for delivery to NJ is high risk. Check retailer shipping restrictions.
Penalties: Fourth-degree crime under 2C:39-3(e) and 2C:39-5(d),(e); NJ fourth degree is up to 18 months (general sentencing law, not re-checked this session).
Recent changes: P.L.2025 c.255 (approved 12 Jan 2026) amended 2C:39-1 and 2C:39-3 on firearms/antiques; We could not read its knife effect. P.L.2018 c.161 changed 2C:39-3 (law-enforcement magazines), knife text unchanged.
Pending changes: Bill A5128 (2026 session) would amend 2C:39-1/2C:39-3; knife changes not confirmed. Check pub.njleg.gov.

Reasons the authorities have accepted

Hunting, fishing or camping trip
Work tool use (trade, kitchen, farm)
Transporting a purchased knife home from the store

What we could not confirm

Verified 2026-10-27 from the enrolled P.L.2018 c.161 text on pub.njleg.gov: 2C:39-3(e) lists gravity knife, switchblade knife, dagger, dirk, stiletto and ballistic knife 'without any explainable lawful purpose' (fourth degree).
