At the school I go to, personal craft knives (utility blades?) that the art and design students NEED to use for their projects have been banned after a boy at another school was stabbed. Only the 'school' craft knives may be used, in a classroom, and only in the presence of a teacher.

<<Start of sarcastic rambling>> Interesting thuohg, that a harmless, 6 inch pair of scissors is still allowed to be carried as part of our stationery. But then of course, nobody would ever dream of using scissors as a weapon <<end of bitter, sarcastic rambling)
