Omicron Knife-Suit
From Multiversal Omnipedia
The Omicron Knife-Suit was a personal battlesuit composed of sentient molecules which is covered in extremely sharp blades. The molecules "live to be sharp...almost spiritually sharp" Extant by the 853rd century in Justice Legion A's timeline, it was "illegal in seventy-eight systems." One of the suits was used by Vandal Savage in his final battle with Resurrection Man.

Savage claimed it was even capable of severing souls from their bodies, but that may have been hyperbole.
