Batarang. It's a funny word. And, until Frank Miller turned them into nasty little shuriken, it's kind of an odd weapon for a grim nocturnal avenger, at first blush. But watch this video and you will never laugh a Batarang again.
The homage to the Dark Knight's ranged weapon of choice comes from Victor Poulin, who crafts all sorts of throwables over here. The first thing I thought while watching that video was, "wow, that's going really far." Then I thought, "that would probably hurt, especially if it were made of metal." Batarang. You don't want to get hit by one. It'd be embarrassing.
