If you were observed by a police officer, they would likely arrest you. NYC does not allow knives to be carried over 4 inches in blade length.

It is funny. Did you know that laws restricting carrying weapons by the peasants is the REASON martial arts exists? Nunchucks are rice threshing tools, etc. they learned to use tools that peasants would naturally carry as very lethal weapons. Lesson learned. Did you know one can make Nunchucks WITH NO METAL?
