Hawaii Knife Laws With All New Updates (2022)

It's a far cry from Aloha when it comes to knife laws in Hawaii. While at a glance it may seem that the knife laws of ‘Paradise’ are blissfully relaxed, a close look reveals a different landscape. Hawaii knife laws wear a grim face behind a smiley mask. They often make little sense to the locals and even less to the tourists. Many are of the opinion that these laws constrain outdoor enthusiasts from enjoying the lush nature that the Aloha State has to offer.

Places like Nā Pali Coast State Park are advertised as some of the most beautiful places on earth. A full experience of these natural wonders demands camping gear. And that includes a capable cutter. But the question begs - what knives are you allowed to carry in Hawaii (if any)? And what knives can you own? Are you allowed to buy switchblades? Here, you'll find answers to questions like these.

What Hawaii Knife Law Says (In Garbled English)

HRS § 134-51. Deadly weapons; prohibitions; penalty.
(a) Any person, not authorized by law, who carries concealed upon the person’s self or within any vehicle used or occupied by the person or who is found armed with any dirk, dagger, blackjack, slug shot, billy, metal knuckles, pistol, or other deadly or dangerous weapon shall be guilty of a misdemeanor and may be immediately arrested without warrant by any sheriff, police officer, or other officer or person. Any weapon, above enumerated, upon conviction of the one carrying or possessing it under this section, shall be summarily destroyed by the chief of police or sheriff.
(b) Whoever knowingly possesses or intentionally uses or threatens to use a deadly or dangerous weapon while engaged in the commission of a crime shall be guilty of a class C felony.


What the Law Really Means (In Plain English)

Knife laws in Hawaii basically allow you to own most knives. You can purchase and possess almost any kind of knife except switchblades and gravity knives. This allows you to lawfully own most folding and fixed blade knives.
