Made from a "space age" Saturnite alloy in the Big Mountain Research and Development Center, cosmic knives were advertised to be super-sharp, all-purpose kitchen knives that wouldn't chip or dull. A surplus of these knives were shipped to the Cantina Madrid kitchens in the Sierra Madre casino in preparation for the Gala Event. Though lightweight and durable, they proved to be too sharp for their own good, easily capable cutting a person's thumb off if they were careless, and even slice through cutting boards with no effort. This made them perfect for cutting open hazmat suits that had their locks corroded by the red cloud in the Sierra Madre during its construction. Concerns were raised about the safety and necessity of having so many of these knives lying about, but Frederick Sinclair insisted that only the best equipment be used.
They were also found to have incredible heat retention, able to stay super-hot for hours after being heated over a stove. However, they are much more brittle when heated, and if left on an uninsulated surface, they would melt right through.
The cosmic knife super-heated was accidentally discovered by a chef, when one was left on a hot (450 degrees) stove under a pot for five minutes. The alloy retained so much heat that the blade glowed red-hot. The handle was safe to hold, but when the chef put it down on a table, it melted the table.
Compared to the regular kitchen knife, the cosmic knife is longer, stained red with cloud residue, and does more damage. Using Abraxo cleaner, one can turn it into a clean cosmic knife. They glow violet before they are cleaned, most likely due to years of cloud exposure. The name "cosmic knife" is a brand name only, referring to the "space-age" Saturnite material it's made of, and not because it originates from outer space.
The cosmic knife super-heated appears as an ordinary cosmic knife with a slight orange glow. Its special V.A.T.S. attack is the Flambé Cut, which does 90% damage at a cost of 20 action points.
The super-heated knife has a very interesting script set up for critical hit attacks: when the player scores a critical hit, there is a 25% chance that enemies will be enveloped in smoke, and a 75% chance they will burst into flames, plus any critical hit will cause the target to begin taking two points of fire damage every second for five seconds.
The script notes for the critical hit effect state, "Randomly generates either small burn DPS + smoke or large burn DPS + fire on hit." but the fire damage effect for both smoking hits and flaming hits is identical.
This item must be crafted by the player, as it is not found on enemies or in containers.

PCPlayStation 3Xbox 360 Although capable of setting non-player characters on fire, this weapon is not affected by the Pyromaniac perk.
PCPlayStation 3Xbox 360 The glow layer texture for this weapon is referenced by the weapon's model, but was not included in the resources for Dead Money. This indicates the weapon was intended to produce a glow from only certain parts of the weapon, but instead provides a glow over the entire weapon due to the missing texture.
