This is so mind boggling I don't even know where to begin. I have had a pocket knife ever since I was in the Cub Scouts (still have it too!), and some how, after all these years, I never felt I was "risking everything" by carry a knife with me.
I truly feel sorry for the British people having to live with this nanny state doctrine foisted on them by spineless, feeble minded politicians and their likewise namby-pamby, social engineering counterparts. I'm certain the people will eventually be restricted to using plastic spoons as their only eating utensils and forced to wear mittens all of the time so they don't poke someone's eyes out. And safety scissors will be the order of the day, provided of course you have the proper permits to have paper and it's safely kept under lock and key.
Rule Britannia! Not likely...
