I've carried a knife everyday for the last 60 years. (I'm 71) My parents knew I always had one with me. My father always had a knife in his pocket as well. Like the vast majority of the population I regard a knife as a tool I use mine every day for various tasks. I've never cut anyone (except myself) and I've never used it in an aggressive manner, and wouldn't dream of doing so. Interestingly enough everywhere I worked people were constantly asking to either borrow my knife or asking me to open something or cut something!
It is dangerous on the mean streets of North Beds, and we do need something to eat a Bedfordshire Clanger with.
