Raibu

Raibu is the indestructible scissor blade owned by Ingane Mordem. It was made by Hemolele Oihana

Meteor Steel
Being that it is made of meteor steel, Raibu is all but indestructible. It is naturally very useful in long drawn out combat or fighting in general.

"Sheathing"
The creator, Hemolele Oihana, used his Kyousha Kyousha no Mi to imbue the sword with the bendability of a ferret. This allows it to be wrapped around the handle when the fighting has stopped, making a large ring that a belt can be strung through.
