A different way of expressing it is that many governments are more willing to restrict individuals rights in order to enhance societal stability. America tends to go the other way.
Which way is best depends on you fondness for nanny statism.
The phrase "nanny state" is a scaremongering weasel-phrase that is only ever used in order to further ideological doctrine. It is a meaningless phrase that libertarians and proponents of let-me-do-what-the-hell-I-like-and-to-hell-with-society-ism use in order to make people suspicious and mistrustful of what is commonly quite reasonable and justified regulation. As soon as you use the phrase "nanny state" in an argument, I know that your argument consists of mere propaganda.
Just out of curiosity, are you willing to take away knives and other weapons too? I have a concealed carry permit and seldom actually carry a pistol concealed. I carry a Gerber paraframe knife every day.
There are already quite reasonable restrictions on knives and other weapons. I've just looked up the legislation for the ACT, and it prohibits flick knives, sheath knives, concealable daggers, butterfly knives, shuriken, trench knives, spring knives, throwing knives and Wolverine claws. It also prohibits nuchakus, tonfas, weighted gloves, maces, flails, metal-studded whips and telescopic batons (among other prohibited articles - the legislation is
here (pdf)). I believe your knife would be legal to own without a permit in this area.
To cut a long story short, yes, I am willing to take away knives and other weapons if they contravene the law.
If I may in turn indulge my curiosity (since we're already slightly off-topic), what do you use your knife for? Do you use it daily? I assume you use it when hunting - anything else?
