Pencil sharpeners banned in British school

This unbelievable story comes to us via Zero Intelligence, a blog that I really need to stop reading if I want to keep the welt on my forehead from growing after banging it against the desk in frustration so much:

PENCIL sharpeners have been banned from a primary school after a pupil dismantled one and used the blade to slash another child's neck.

...

The attacker was suspended for two days and is now back in school.

So what happens if one student attacks another by using a pencil as a stabbing weapon? Ban pencils (and all other writing implements)? I got into an eraser-throwing fight with friends in my younger days and accidentally hurt one of them. I guess the school officials would have had to ban erasers from the school because of that if "zero tolerance" had existed back then (about 15-20 years ago).
