I'm not sure how they make you safer, but do you have any friends in law or law enforcement that you can check with?
Well, having a way to defend yourself and tilt the odds a bit if attacked will obviously make a person safer. I do have a couple friends in law enforcement, I'll have to ask them next time I see em. Funny thing about police in the U.S. is that sometimes when someone isn't doing anything illegal, but are doing something a police officer thinks SHOULD be illegal, they'll get locked up anyway until the cop is informed that there is no law the person was violating. Makes for a dandy "wrongful arrest" lawsuit if one were so inclined. Maybe I should print off the "unlawful use of weapons" statute and keep it in my wallet for ignorant officers.
I would check out something much more effective and legal (pocket knife.)
I don't really feel comfortable with a knife in a defensive situation because of my lack of skills, and the way those types of confrontations usually turn out.. they say there are no winners in a knife fight. If by some chance my weapon was taken and used against me, I'd rather have it be plastic knuckles than a knife any day.
Does Illinois allow CCW?
Also, if you're looking for lawful impact weapons, you should check out kubatons.
Illinois is one of two states that do not allow CCW. Funny thing too, I just got my Florida non-resident CCW permit in the mail, and 28 states trust me enough to carry a concealed handgun in... many other states allow "open carry"... but the state I reside in, and pay taxes to, does not permit me to defend myself and my family effectively outside of my home, open OR concealed.
As far as I know, this does not classify as a concealed weapon though. I did look into kubatons, aka "keychains" and am deciding between one of those and these polymer knuckles.
Here's what I found from Illinois state law-
(720 ILCS 5/24-1) (from Ch. 38, par. 24-1)
Sec. 24-1. Unlawful Use of Weapons.
(a) A person commits the offense of unlawful use of weapons
when he knowingly:
(1) Sells, manufactures, purchases, possesses or
carries any bludgeon, black-jack, slung-shot, sand-club,
sand-bag,
metal knuckles, throwing star, or any knife,
commonly referred to as a switchblade knife, which has a
blade that opens automatically by hand pressure applied to
a button, spring or other device in the handle of the
knife, or a ballistic knife, which is a device that propels
a knifelike blade as a projectile by means of a coil
spring, elastic material or compressed gas......
