I also find it interesting that some of the countries with Viking/Teutonic/Norman/Celtic heritages are the most limited on what they can carry1
I read an article once where allegedly Scotland was trying to outlaw all knives with points because folks were stabbing each other. I'm not making that up it was an actual article with proposed legislation.
It is already illegal to stab people, but people still do that...
Making pointy knives illegal won't make people who stab other people say; "oh well, I guess stop stabbing people now". Stupid!
