Yoru

"Without subtlety, a sword is but an iron bar." — Mihawk on the Kokoutou Yoru

Known to be the strongest Sword in the world; Kokoutou Yoru is an ornately decorated, man-sized (6 foot) sword shaped like a cross with a shiny black blade, curved at the end making it somewhat similar to the German grosses messer. Also, it seems to generate otherworldly purple streaks as it slices, as seen when it was used to cut down Zoro and when it split Don Krieg's ship in half. While Kokutou Yoru is the sharpest blade in the world, it is also gentle. This was as demonstrated when Mihawk deflected the course of bullets that were aimed at him with only a slight touch of the sword.
