There are no pros as regards carrying a knife with the intent to cause injury ,and that includes carrying one for ''protection''. If you use knives in your occupation say a chef or a builder or woodcarver then your tools of the trade can be carried in a secure holder like a knife roll or toolbox preferably a lockable carrier. Carrying a knife gives a false sense of superiority and 99 times out of a hundred it will be the carrier of the blades who are injured.
The last government promised that carrying a knife would carry a mandatory five year jail term however the average sentence for carrying a knife is less than three months with the perpetrator usually out in less than a month.
There is no need to carry one in the city Thats asking for trouble, But this anti-knife law is annoying for people in the country who need knives or for camping when you may have to pass through a town carrying a knife. I think any one who needs a knife should have a knife licence or something.
