Eisen Whip

This sword is the personal weapon of Ohm, one of the priests serving in the upper sky. At a glance it looks like an ordinary katana kept in a white scabbard, the only oddities being the Dial mounted at the pommel and the unusual color of the blade.

The weapon's secret is the Eisen Dial fitted into its base, which pours out a continuous stream of Iron Cloud that serves as the cutting edge. This material is as hard as iron yet as light as cloud, so Ohm can mold the blade into whatever form a moment calls for, switching freely between attack and defense to create an extremely adaptable and lethal weapon. His named techniques all open with the word Eisen, German for iron, fitting the iron-cloud nature of the sword.

Ohm alone wields the Eisen Whip, deploying a range of shaped attacks against his enemies. Eisen Whip lashes out like a high-speed projectile, Eisen Back raises a solid defensive wall, Eisen Fan spreads the blade into a fan to strike with, Eisen Fork turns it into a giant fork swung like a whip, and Eisen Fleuret projects it as a long fencing-style spear. The fighting game One Piece: Grand Adventure adds many more exclusive shapes, such as blade, hammer, axe, and trident variants.
