The sword is part of a total set of armour called Hiabusa armour.To get this armour you have to get all vidmaster achivements.To do this beat the game on legendary and try to get all skulls possible.My gammer tag id NewDR XYZ.Hope this helps.

your only supposed to get the original 49 achievements for the katana but i was getting the achievements and then all of a sudden had the katana. i had about 40 of the achievments and the security armor would sometimes showed up, but when i tried to set it to katana and stuff, the armor would disappear. all you have to do is make your armor security, then when it switches to mark IV switch it to something else then to security again. tada
