I'm not sure on the state-to-state specifics about carrying fighting fans, although they are a pretty innocuous item so my suspicion is that there aren't any laws against them.

These are indeed good quality and are durable when used as intended (meaning when open they aren't designed to take hard blocks or create cuts).

Paul - this fan is made from aluminum, but does not have a distinct blade on the side of it.

The fighting fan is a versatile weapon that can be used both open and closed. When closed, it creates a durable thrusting weapon to the face, eyes, etc. When open it can be used to distract and disorient attackers. The benefit of the fighting fan is that it can be carried without being obvious as a weapon. To learn more about using the fan properly, consult a skilled instructor in your area.

I wish i knew how to use it and in soo bahk do they dont teach you how to use weopons.
