While there have been countless Barbie spin-offs, this Swiss Army Barbie may be the most practical role she's taken on yet. 'Instructables' user Mike Saurus shows off how he made his DIY Barbie into a knife that is both fashionable and functional.
To turn Barbie from pretty to pretty scary, all that's needed is a multi-blade knife, a doll and a hand saw. Whether this Swiss Army Barbie is really a good toy for children or not is debatable, with Saurus believing it can "empower young girls to expand their horizons beyond playing with stereotypical gender-reinforcing toys."
Since considered too dangerous to entrust to a child, it can feature as a comical addition to an adult's toy or tool collection -- be it of barbies or knives.
