Zero Knife, Frostbite-Class
A zero knife appears much like a folded switchblade, though the hilt is somewhat bulkier due to the battery; when activated, the zero knife forms a blade formed entirely of an aura of intense cold rather than steel. The frostbite-class zero knife is an easily obtained weapon whose blade rapidly accumulates flakes of frozen material in most atmospheres. The more advanced hailstorm-class, blizzard-class, avalancheclass, and icequake-class zero knives incorporate technology that eliminates the build-up.
