The Unbreakable Japanese Sword

The legendary weapon of Geg. This fabled and all powerful blade was said to be forged in the heart of a dying star out of the hardest metal in all of creation and fiction. It is said that the blade material was the basis of the plot of the movie Avatar (aka that movie where people fuck plants and animals with their pony tails.) Geg once personally said that the reason avatar had to filmed twice and lost money despite it making over TWO AND HALF BILLION dollars was because the metal (Unobtanium) used to forge the sword cut through the fabric of reality around it. This sword is BY FAR the most powerful weapon in all of reality as nothing could even possibly come close to the shear destructive capability that this weapon holds.
