You cannot carry a concealed weapon that is over six feet in length.

The Law Explained

This bizarre restriction was likely born out of a mix of standard concealed carry laws and the logistical absurdity of trying to hide a spear or a giant sword in your coat. Lawmakers apparently felt the need to specify a maximum length for concealed items to prevent loopholes during early 20th-century street brawls. Good luck trying to hide a polearm in your trench coat anyway.
