Saturnite

Saturnite was a man-made "space-age" ceramic material developed by the military and was used in the making of Cosmic knives and the D-25A power fist.

As indicated by the presence of blue artillery grenades inside the Saturnite Alloy Research Facility, Saturnite might have also been used in the creation of these artillery shells since ceramic materials are known to be lightweight, noncorroding and hard at the same time.

Characteristics
Saturnite has a few unique characteristics making it special such is as the ability to retain heat when heated and the ability to stay razor sharp after cutting through wood, metal, and even bone.
