In the Netherlands we have a similar thing happening.
The last 2 months we had some sad stabbing incidents in and around schools.
The Minister of Justice turned out to be smart person when this week he claimed that most stabbing incidents involve the use of knives
Good point, a lot of knives are suitable for stabbing.
Suggestion now is to ban knives such as stilleto's and butterflyknives, which personally I don't mind.
But as a whole this decission ofcourse is the same reaction you see in the UK. Next time somebody might us a screwdriver for stabbing.
And what are we going to do than, ban screwdrivers ?
