Saturnite

Saturnite is a space-age, ceramic-like alloy developed in the Big MT for use in a variety of fields, including cosmic knives, the D-25A power fist, experimental armor plating, artillery shells , and many other items.

Characteristics
Saturnite has a few unique characteristics such as its uncanny sharpness, hardness, and its ability to retain heat for extended periods of time. Like other ceramics, it has a very high strength-to-weight ratio. However, the alloy seems to decay in contact with the toxic cloud of the Sierra Madre.
