This version of the legendary katana wielded by the Dark Knight Vergil from the Devil May Cry series is from the specific 2005 CG renderings of the characters and weapons.
I think of this style of the Yamato is the most elegant and clean out of all the designs. I imagine this version to be the Yamato that was restored after being shattered in the Underworld by Mundus.
I would love to see this modded in DMC5 not sure if its in the right format though.
