This paper model is Sailor Saturn's Silence Glaive, the weapon that Sailor Saturn uses in battle, based on the manga series Sailor Moon (known in Japan as Pretty Soldier Sailormoon), the papercraft is created by Mickey103.
It was used in mostly all of her attacks and appeared in all continuations of the series. When she swung the glaive down without saying any words, the entire planet she was destroying would turn into dust. It directly harnessed the power of Sailor Saturn's most powerful attack, a tecnique that was performed to its fullest extent once in the manga, after the fall of the Moon Kingdom in the Silver Millennium. Sailor Saturn's ultimate attack using the weapon would also result in her own death. [Source: wikia]
