Ethereal Edge

The Ethereal Edge is Necrid's joke weapon in Soul Calibur II.
 * "So wispy and so useless."
 * — Weapon Gallery description.

"This vaporous weapon is formed from a collection of particles so faint, one questions whether or not it actually exists. The reflections from its ever-changing form are beautiful to behold, but deemed by many as nothing more than a mere trick of light. No weapon is more suitable, however, for catching unsuspecting enemies off-guard."
