Michigan Knife open Carry laws

Currently all knives that are not considered to be illegal, and are not carried with intent to harm, may be open carried. However, cities, counties, and other districts or legally capable communities may enforce more strict laws in their particular area of influence. This is completely dependant on the individual area.

Michigan Concealed Knife laws

Michigan Penal Code 750.227 (1) A person shall not carry a dagger, dirk, stiletto, a double-edged nonfolding stabbing instrument of any length, or any other dangerous weapon, except a hunting knife adapted and carried as such, concealed on or about his or her person, or whether concealed or otherwise in any vehicle operated or occupied by the person, except in his or her dwelling house, place of business or on other land possessed by the person. […] (3) A person who violates this section is guilty of a felony, punishable by imprisonment for not more than 5 years, or by a fine of not more than $2,500.00.

The Michigan Penal Code goes on to clarify ‘double-edged, nonfolding stabbing instrument”

750.222a (1) As used in this chapter, “doubled-edged, nonfolding stabbing instrument” does not include a knife, tool, implement, arrowhead, or artifact manufactured from stone by means of conchoidal fracturing.

(2) Subsection (1) does not apply to an item being transported in a vehicle, unless the item is in a container and inaccessible to the driver.

Simply put, weapons which could be used to stab are illegal to carry concealed. This means that the only knives which are legal to carry concealed would be knives with a blunt end and/or knives which fold and do not meet any of the above listed disqualifications for concealed carrying.

It’s important to note that while these knives can thusly be carried openly, they cannot be carried in a vehicle. This means that you cannot travel large distances with this knife, concealed or otherwise, on or near to your person. This means that you can place them in a secure area which cannot be accessed by anyone in the vehicle, as this would take them from being a carried knife to a transported knife. For example, you can place one of these knives into a case and then into your trunk, eliminating access to it from you or any of your passengers.

Michigan Knife laws Length

Currently there are little to now laws with regards to the length of a blade. The only mention is that blades of or over 3 inches may not be carried with the intent to harm another human. However, the law also states any dangerous weapon are illegal regardless of blade length.

Pocket Knife laws in Michigan

Pocket knives are legal to own and carry, open or concealed, under Michigan law, so long as there is no intent to harm. So long as it is considered a pocket knife it will be legal to carry as such.

Michigan Knife laws Fixed Blade

Fixed blade knives may not be carried concealed, unless they are a hunting knife and are being carried for such a purpose. The exceptions with regards to this law would be that if you are on your private property, be it a home, land, or business, then it is legal to do so.

As well, it is illegal to carry these, concealed or otherwise, in a vehicle unless under the same exceptions. The means to get around this is to place the blade in a secure container and then into a position where it cannot be accessed by any individual in the vehicle, such as the trunk of the car.

Michigan Butterfly Knife laws

Butterfly knives have long been the exception to the old laws which ruled that automatic or gravity blades were illegal to carry. So long as it is not a butterfly knife with a double edge design and is not carried with intent to harm it may be carried concealed.
