It’s no secret that the Brothers Grimm fairytales tend to be much darker than their animated-movie counterparts, but the true tale of Cinderella featured more knife-wielding girl power than shoe-obsessed love connection. As legend goes, the original tale was changed to keep Cinderella’s glass knife – which will turn to glass anyone impaled by it – a secret (did you really think anyone could dance all night in glass slippers?). Featured on-screen in the second-season Warehouse 13 episode “Where and When,” Cinderella’s glass knife is now being made available at VIP Fan Auctions to the lucky fan who casts the winning bid.
