Chopstick Shank

::My tertiary co-teacher shows me a sharpened, metal chopstick that I assume he either found laying about or took from a student::

Mr. J: This--very dangerous.
Me: In America, we call that a shank. People have those in prisons! Why would a student have one?!

He giggled and said nothing further.

I was shocked because it's so ridiculously safe here, that anyone stabbing anything just seems so implausible. At the same time, friends smack the shit out of each other in class a lot here. It's horse play, but they hit pretty hard. And it seems to be acceptable to a degree. Unless a ruckus begins to mount, none of my co-teachers react to it at all. But I really doubt that deep, puncture wounds are really what anyone's going for. Maybe they're lawn darts.

Also, I was secretly impressed by the craftsmanship of said shank.
