According to the design page, this brass knuckle umbrella or "Umbuster" was categorized as a class 5 weapon by the Victorian Police—the primary law enforcement agency in Victoria Australia. That would make it illegal to own there without a license. I don't know about all of that considering that it appears to be a concept, but I do know you could do some serious damage with it. Then again, if you got in a scuffle in the rain, the drag from the open umbrella may render your punch harmless—resulting in a swift and brutal ass kicking. [Sruli Recht via Likecool]
