Hawaii has unique knife laws that can be a bit tricky to navigate. While owning knives of various types is generally legal, there are restrictions on certain types of knives and how they can be carried.
In this guide, we’ll break down the basics of knife laws in Hawaii, including what you can own, how you can carry knives, and what types of knives are banned in the state.
What is Legal to Own in Hawaii?
In Hawaii, you are allowed to own a variety of knives. Here’s a breakdown of what is legal:
- Bowie Knives and Large Knives
You can legally own Bowie knives and other large knives. There are no restrictions on these types of blades as long as they are not carried in a way that violates other laws. - Throwing Knives and Stars
Throwing knives and throwing stars are also legal to own in Hawaii. However, if used in an inappropriate manner (e.g., to cause harm), they could be classified as a dangerous weapon. - Disguised Knives
Disguised knives, like belt knives, lipstick knives, and push knives, are legal to own. These knives are often hidden within other everyday items, making them more difficult to spot. - Undetectable Knives
Undetectable knives, which are knives that do not set off metal detectors, can also be owned legally in Hawaii. However, these knives may be subject to federal regulations if they are used to bypass airport security or similar checks. - Dirks, Daggers, and Stilettos
Dirks, daggers, and stilettos are legal to own in Hawaii. These types of knives are typically used for stabbing and have a double-edged blade.
What is Illegal to Own?
While Hawaii allows ownership of many types of knives, there are a couple of exceptions:
- Balisong Knives (Butterfly Knives)
Balisong knives, also known as butterfly knives, are illegal to own in Hawaii. These knives have a blade encased in a split handle that unfolds with a flick of the wrist. Possessing, manufacturing, selling, or transferring a balisong knife is prohibited. - Switchblades
Switchblades, or automatic knives, are also banned in Hawaii. These knives have a blade that opens automatically by pressing a button or by the force of gravity or inertia. Carrying or possessing switchblades can result in criminal charges.
Limits on Carrying Knives in Hawaii
In Hawaii, there are restrictions on how knives can be carried, especially regarding concealed carry:
- Concealed Carry and Open Carry
The issue of concealed carry and open carry is straightforward in Hawaii. If a knife is classified as a “dangerous weapon,” such as a dirk or dagger, it cannot be carried either concealed or openly. This includes weapons that are designed primarily for combat, like metal knuckles or slingshots. However, knives like tactical knives, Bowie knives, and other large knives are not automatically considered dangerous weapons unless used in a way that makes them a threat (for example, using a knife to threaten someone). - No Blade Length Restrictions for Concealed Carry
There is no specific blade length restriction for concealed carry in Hawaii. However, the manner in which the knife is carried and used will determine if it is classified as a dangerous weapon. For example, carrying a knife in a threatening way could result in criminal charges.
The Law Says: Hawaii Revised Statutes (HRS)
Here’s a summary of the legal framework regarding knives in Hawaii:
- HRS § 134-51: This law makes it illegal to carry dangerous or deadly weapons, including dirks, daggers, blackjack, metal knuckles, and pistols, either concealed or openly. If you are found carrying one of these weapons, you can be arrested and convicted of a misdemeanor.
- HRS § 134-52: This law prohibits the possession or transportation of switchblade knives in Hawaii. Violating this law can result in misdemeanor charges.
- HRS § 134-53: This section bans the possession or transportation of butterfly knives in Hawaii, with the same misdemeanor penalties for violations.
Notable Legal Cases on Knife Carrying
Several legal cases in Hawaii have helped define what is considered a “deadly or dangerous weapon.” Here are key takeaways:
- State vs. Giltner (1975)
The case clarified that a deep-sea dive knife, even though it had a 6.5-inch blade, was not considered a deadly weapon because it was intended for underwater use and not as a combat weapon. This case established that the knife’s intended use is an important factor in determining whether it is classified as a dangerous weapon. - State vs. Muliufi (1982)
In this case, the court ruled that nunchaku sticks, which are primarily used for martial arts training, are not considered deadly weapons. The court expanded the definition of a deadly weapon to mean an instrument designed primarily for combat or modified for combat purposes. - State vs. Rackle (1974)
The court determined that not all knives should be automatically considered deadly or dangerous weapons just because they are knives. The manner in which the knife is used must be considered, and knives not classified as dirks or daggers are generally not considered dangerous unless used in a threatening manner.
Knife Ownership and Carrying in Hawaii
In Hawaii, you can own almost any type of knife, except for balisongs (butterfly knives) and switchblades. While you can carry knives openly, you cannot carry knives that are classified as dangerous weapons, such as dirks or daggers, either concealed or openly.
The key to staying within the law is how the knife is used—if you use a knife in a way that is perceived as threatening or dangerous, you could face legal consequences.
Before carrying a knife, always make sure you understand the specific laws and how they apply to your situation. If you’re unsure, it’s wise to consult a local attorney to avoid any legal issues.
