Wisconsin has specific laws regarding the possession and carry of certain types of knives. It is crucial to know and understand these laws to avoid any legal consequences. In this article, we will discuss what knives are illegal in Wisconsin and the penalties associated with their possession or use.


In Wisconsin, switchblades are illegal to possess or carry. A switchblade is a knife with a blade that can be automatically deployed by pressing a button, switch or other mechanism. The possession of a switchblade is considered a Class A misdemeanor, which can result in fines up to $10,000 and imprisonment for up to 9 months.

Balisongs (Butterfly Knives)

Balisongs, commonly known as butterfly knives, are also illegal in Wisconsin. These knives have a unique design that allows the blade to be concealed within the handle and can be quickly deployed with a flick of the wrist. Possessing or carrying a balisong is considered a Class A misdemeanor, similar to switchblades.

Gravity Knives

Gravity knives, which operate by the force of gravity to open and lock the blade in place, are prohibited in Wisconsin. Possessing or carrying a gravity knife is a Class A misdemeanor. It is important to note that even possessing a gravity knife with the intent to use it unlawfully is also illegal.

Brass Knuckles with a Knife

Brass knuckles with an integrated knife blade are illegal to possess or carry in Wisconsin. Brass knuckles are considered dangerous weapons, and attaching a knife to them increases their potential harm. Violating this law is a felony, which can result in imprisonment for up to 3 years and fines up to $10,000.

Concealed Carry

In Wisconsin, it is generally legal to openly carry a knife, as long as it is not one of the prohibited types mentioned above. However, if you wish to carry a concealed knife, there are additional regulations to consider. Wisconsin law requires a concealed carry license for carrying a concealed weapon, including a concealed knife. It is advisable to obtain the necessary license to avoid any legal issues.


There are certain exceptions to these knife laws in Wisconsin. For example, individuals involved in specific professions, such as law enforcement officers, military personnel, and firefighters, may be exempt from these restrictions while performing their official duties. It is essential to understand these exceptions and ensure compliance with the law.


Knowing what knives are illegal in Wisconsin is crucial to avoid legal troubles. Switchblades, balisongs, gravity knives, and brass knuckles with a knife blade are prohibited, while other types of knives can be openly carried. However, if you plan to carry a concealed knife, make sure to obtain the necessary concealed carry license. Understanding and complying with these laws will help ensure your safety and legal standing within the state.
