Legal Fixed Blade Length in Michigan: Key Rules & Limits

By Anthony SmithJanuary 30, 2026

In the Wolverine State, knife laws can be a bit of a labyrinth, with varying regulations across different cities and counties. One of the most common questions among Michigan residents and visitors alike is: "What is the legal fixed blade length in Michigan?" Let's delve into this topic, ensuring you stay informed and on the right side of the law.

Michigan's knife laws are primarily governed by the Michigan Penal Code, Act 328 of 1931. However, it's crucial to note that local ordinances may also apply, potentially leading to variations in regulations across different jurisdictions. Always check with your local law enforcement or prosecutor's office for the most accurate and up-to-date information.

Understanding Michigan's Knife Laws

Michigan's knife laws are relatively permissive, allowing for the open carry of most knives. However, there are some restrictions and nuances to be aware of.

Firstly, it's essential to understand that Michigan does not have a specific law regulating the length of fixed-blade knives. This means that, in theory, you could carry a fixed-blade knife of any length openly. However, this doesn't mean there are no restrictions at all.

Concealed Carry Restrictions

While Michigan allows for open carry of knives, there are restrictions on concealed carry. According to Michigan law, a knife with a blade more than 5 inches long cannot be carried concealed without a permit. This restriction applies to both fixed-blade and folding knives.

It's worth noting that this restriction only applies to concealed carry. If you're carrying your knife openly, you can do so regardless of its blade length, as long as you're not violating any local ordinances.

Prohibited Knives

Michigan law prohibits the carry of certain types of knives, regardless of their blade length. These include switchblades, gravity knives, and other automatic knives. It's also illegal to carry a knife with a double-edged blade, such as a dagger or dirk, if the blade is more than 3 inches long.

Again, these restrictions apply to both open and concealed carry. If you're found in possession of a prohibited knife, you could face criminal charges.

Local Ordinances and Exceptions

While Michigan state law allows for the open carry of knives of any length, some cities and counties have enacted their own knife laws. These local ordinances can sometimes be more restrictive than state law.

For example, some local governments may have their own restrictions on the length of fixed-blade knives that can be carried openly. Others may prohibit the carry of knives in certain locations, such as schools or government buildings.

Hunting and Fishing Exceptions

Michigan law does provide some exceptions to its knife restrictions for hunters and fishers. If you're engaged in lawful hunting or fishing, you can carry a knife, regardless of its blade length, as long as you're not violating any local ordinances.

However, it's important to note that this exception only applies while you're actually engaged in the activity of hunting or fishing. If you're carrying a knife with a blade longer than 5 inches, you should ensure it's being carried openly and not concealed.

Self-Defense Considerations

In Michigan, you have the right to use force, including deadly force, in self-defense. However, the use of force is subject to certain restrictions and limitations. If you're carrying a knife for self-defense, it's crucial to understand these laws and ensure that your actions are justified under Michigan's self-defense statutes.

In particular, you should be aware of Michigan's "stand your ground" law, which allows you to use deadly force in self-defense without first retreating, as long as you're not engaged in certain criminal activities and you're not in a place where you're prohibited from using deadly force.

In conclusion, while Michigan's knife laws are generally permissive, there are still some important restrictions and considerations to keep in mind. Always ensure that you're complying with both state and local laws, and remember that even if a knife is legal to carry, it's still a dangerous weapon that should be handled responsibly. If you have any questions or concerns about Michigan's knife laws, it's always a good idea to consult with a legal professional.
