Mecha Naruto wrote: I think we should only consider weapons which take permanent physical form I think this is the best. Define a weapon as being able to be permanent. There's no indication that Yata or Totsuka are limited to Susanoo, as they were things Orochimaru sought after. Orochi's Kusanagi is used in jutsu but it's a permanent weapon.

Note that i said "be able to" as the reason most weapons blur this line is because it's convenient to "store" it. Orochimaru stores it in his yuck way, Itachi stores Yata and Totsuka via his Susanoo.
