It's estimated 25% of teens carry a knife. I am closely associated with a local hostel with a high propotion of 18-25s. If the number of characters there who carry a knife everywhere is reflected throughout the country, that figure is nearer 60%. What worries me is not the act of carrying a knife as casually as carrying a mobile, but the ease they will use it. Even on the most trivial of matters. If this escalates, then carrying a knife will be commonplace by all regardless of age. Then it escalates further to guns.
