Michigan Knife Laws: Understanding Legality

Understanding Michigan knife laws is crucial to avoid legal trouble. While Michigan law does not explicitly restrict knife length for open carry, there are specific regulations and interpretations that govern what constitutes a legal blade. This guide will explain the key aspects of Michigan knife laws, focusing on the common question: "what size knife is legal to carry in michigan?"

Open Carry vs. Concealed Carry

Differentiating between open and concealed carry is essential for navigating Michigan knife laws.

Open Carry

Generally, Michigan law permits the open carry of knives, including those that might be considered dangerous. However, this right is not absolute and is subject to certain limitations.

  • Definition: Open carry means the knife is plainly visible and not hidden from view.
  • Legality: While generally legal, openly carrying a knife with the intent to use it unlawfully against another person is a crime. Even without such intent, open carry might be problematic in areas with local ordinances restricting knives or where it causes public alarm leading to a disturbance.
  • Exceptions: Certain places, such as schools (K-12) and courthouses, may prohibit the open carry of knives, regardless of size or intent.

Concealed Carry

Concealed carry of a "dangerous weapon" is generally prohibited in Michigan without a concealed pistol license (CPL), and even then, only applies to certain types of knives.

  • Definition: Concealed carry means the knife is hidden from view.
  • Legality: Carrying a dirk, dagger, stiletto, double-edged non-folding stabbing instrument of any length, or any other dangerous weapon concealed on your person or in a vehicle without a CPL is illegal.
  • CPL and Knives: Having a CPL does not automatically authorize concealed carry of all knives. It's primarily for firearms. The statute concerning concealed weapons makes a distinction based on the type of knife and, unfortunately, leaves a lot to interpretation in court.

Michigan law does not specify a maximum legal blade length for knives. However, the legality often depends on the type of knife, the intent of the carrier, and where it is carried.

Relevant Factors:

  1. Type of Knife:

    • Folding Knives: Pocket knives, utility knives, and other folding knives are generally considered legal to carry, both openly and concealed, provided they are not designed for primarily stabbing, like a dirk or dagger. The intent behind carrying the knife is critical.
    • Fixed Blade Knives: Carrying a fixed-blade knife, especially if it's designed as a weapon (e.g., a fighting knife), can be problematic, particularly if concealed.
    • Automatic/Switchblades: Michigan law restricts the sale, manufacture, and possession of automatic knives (switchblades). These are generally illegal to carry, regardless of size.
    • Daggers, Dirks, Stilettos: Carrying these types of knives concealed is illegal regardless of blade length, even with a CPL.
  2. Intent: Carrying any knife with the intent to use it unlawfully against another person is illegal, regardless of the knife's size or type.

  3. Location:

    • Certain locations, such as schools (K-12), college campuses, courthouses, and correctional facilities, often have specific prohibitions on knives, regardless of size or type. Check local ordinances.
    • Private businesses can also prohibit knives on their property.
  4. Local Ordinances: Municipalities may have local ordinances that further restrict knife possession and carry. It's important to research local laws in the specific area where you intend to carry a knife.
