Knife amnesty results

British police conducting a knife amnesty (sic) program were quite surprised at one item. Lacking the cultural sensitivity of us Americans, they overreacted and probably offended a population that you really, really shouldn't.

Geek points to anyone who can name the weapon (and spell it correctly). Extra geek points for cartoon links.

(PS: "Knife amnesty"? WTF? Did the NRA make this up? What's next, baseball-bat -- I mean, cricket-bat -- amnesties?)
