I keep a Swiss Army Tool on my car/house keyring because it has everything I need should my car break down or should I need a cutting implement or screwdriver for my daily needs or in my lab. However, due to the recent elevation in high profile stabbings and this new "knife amnesty" thing brought in by the police in Britain, should I be worried say, if I travel on the tube and my keys are in my bag and Im randomly searched? Is it is tool or will the warped sense of the law just bend me over and throw me in the clink? I mean, I carry a pencil case as well: full of sharp, pointy pens which I could easily gouge into someone's neck if I was that was inclined!?
