My school rulebook specifically bans ninja stars and nunchaku.

As far as the locker searches go, I dont think its a massive inconvience for them to search a locker, especially since, if you've got nothing in there that is illegal, you wont get in trouble, and they aren't going to ruin your day by checking. At least, I hope not. :-p

Genia pretty much said it with the Aim sniffer.
