Sorry, but how many kids stabbed this year in London? and it's not a problem? One is too many. I'm shocked at the apathy. No, its not common in school - thank heavens. But it beggars the basic question of what is going on that we don't know about? I very much doubt that this is the only kid who has a weapon on them at school. My primary school - yes - a year 6 primary school kid - in Herne Hill - was caught with a knife and threatening another child. It is not common, but it is not unheard of. And denying the existence of something you don't like isn't going to make it go away.
