Hawaii Knife Laws (2026) – What You Can Legally Carry

Hawaii’s knife laws underwent dramatic liberalization in May 2024 when the state repealed longstanding bans on switchblades, butterfly knives, and gravity knives. This marked a significant victory for knife rights advocates and brought Hawaii more in line with mainland knife freedoms. Most recently, the state legislature defeated SB 433 in February 2026, a bill that would have reimposed severe restrictions. Understanding Hawaii’s current laws is essential for residents and the millions of tourists visiting the Aloha State.

Major Legislative Changes (2024-2026)

May 2024: Historic Knife Law Reform

Hawaii repealed its bans on several knife types in May 2024, ending decades of restrictive legislation:

Newly Legal Knives (May 2024):

• Switchblades and automatic knives
• Butterfly knives (balisongs)
• Gravity knives
• Spring-loaded knives

This reform made Hawaii one of the more permissive states for knife ownership and carry, a dramatic shift from its previous restrictive stance.

February 2026: SB 433 Defeated

In early 2026, the Hawaii legislature proposed SB 433, which would have:

• Banned carry of most “bladed weapons” statewide
• Criminalized everyday tools like pocket knives, box cutters, and fishing knives
• Created broadly defined “sensitive locations” where even legal knives would be prohibited
• Threatened traditional hunting practices with knife and bow restrictions

Community Response:

• Over 400 people testified against the bill
• Law enforcement agencies opposed the legislation
• Civil rights and legal aid groups testified against
• Only 4 individuals supported the bill

Result: The Senate Public Safety and Military Affairs Committee deferred SB 433 indefinitely in February 2026, effectively defeating it for the legislative session.
