Butterfly Knife laws in Michigan

In Michigan, butterfly knives, also known as balisongs, are subject to restrictions primarily under laws pertaining to switchblade knives and prohibited weapons. MCL 750.226 explicitly prohibits the possession, carrying, or use of dangerous weapons, which can be interpreted to include butterfly knives depending on construction and intent. While not always explicitly named, their nature as folding knives with a blade that can be rapidly deployed can lead to them being classified similarly to automatic knives or switchblades under state law, which are generally restricted. Violations of Michigan's prohibited weapons laws can result in misdemeanor or felony charges, depending on the specifics of the offense and prior convictions. Penalties may include significant fines and incarceration. For instance, carrying a concealed weapon unlawfully is a felony, and possessing certain prohibited weapons can also lead to felony charges. The practical application of these laws, especially concerning the definition of "dangerous weapon" and "switchblade," can lead to varying interpretations by law enforcement and courts. Regarding practical considerations, Michigan law generally permits open carry of knives, but the classification of a butterfly knife as a prohibited weapon could impact this. Concealed carry of such knives is almost certainly prohibited. Residents and travelers should be particularly aware of local municipal ordinances, as these can impose stricter regulations on knife possession and carry than state law. Furthermore, for air travel, the Transportation Security Administration (TSA) prohibits butterfly knives in carry-on luggage, though they may be permitted in checked baggage under specific packing requirements.
