Understanding Your Knife Rights in Michigan: A Legal Guide

Understanding your knife rights in Michigan requires a clear grasp of state statutes, local ordinances, and the practical realities of carrying and using knives. Here’s a comprehensive legal guide to help you navigate Michigan’s knife laws in 2025:

Key Michigan Knife Laws

Open Carry:

Any knife can be openly carried in Michigan, provided it is not carried with unlawful intent.
Double-edged, non-folding stabbing instruments (daggers, dirks, stilettos) are legal to own and openly carry, but they are not favored by law and may draw police attention.

Concealed Carry:

Folding knives with blades under 3 inches: Legal to carry concealed.
Daggers, dirks, stilettos, and double-edged non-folding stabbing instruments: Illegal to carry concealed, including in vehicles, unless in your home, place of business, or on land you possess.
Switchblades and automatic knives: Legal to own and carry if single-edged and not carried as a dangerous weapon. Out-the-front automatic knives (those that do not fold) are prohibited from concealed carry.

Possession and Intent:

Carrying any knife with intent to use it unlawfully against another person is a felony, punishable by up to 5 years in prison or a $2,500 fine.
A “dangerous weapon” is defined as any object carried as a weapon for bodily assault or defense, likely to cause serious injury or death when used as a stabbing weapon.

Transporting Knives in Vehicles:

Folding knives under 3 inches: Generally legal to transport.
Double-edged, non-folding knives: Illegal to possess in a vehicle unless you are transporting them to or from your home, place of business, or land you possess—and even then, strict rules apply. In practice, it is safest to avoid transporting these knives in vehicles unless absolutely necessary and in compliance with the law.

Local Ordinances:

Detroit and Lansing have stricter knife laws.
- Detroit: Illegal to carry any knife with a blade over 3 inches in public, whether open or concealed.
- Lansing: Similar restrictions may apply; always check local codes.

Exemptions:

Law enforcement, military, and individuals using knives for legal business or employment purposes are exempt from certain restrictions.
Knives used for hunting, fishing, or camping are also exempt from some restrictions, provided they are carried openly and for legitimate purposes.

Practical Tips for Knife Owners

Know the Law: Familiarize yourself with both state statutes and local ordinances.
Open Carry: If you choose to carry a knife, open carry is generally safest, especially for larger or fixed-blade knives.
Concealed Carry: Stick to folding knives with blades under 3 inches if you want to conceal them.
Transportation: When transporting knives, keep them visible or securely stowed in the trunk if possible.
Intent Matters: Never carry a knife with intent to use it unlawfully.
Check Local Rules: Always verify local ordinances, especially in cities like Detroit and Lansing.
