Who owns the Saber?

Who, may I ask, is the rightful owner of the Saber? Is it a single individual, a collective group, or perhaps an institution? Has the ownership of this esteemed asset been officially documented and recorded? Are there any disputes or claims over the Saber's ownership that have arisen in the past, or are there any pending legal proceedings that could potentially affect its ownership status? I am intrigued to know the full story behind the Saber and its enigmatic owner.
