Codename: Carmina
Carmina is a highly experimental (and very classified) fully-functional portable nanite manipulator. In the absence of a prepared fabrication program, Carmina overrides the behavior of nearby nanites, summoning them to itself until a mass of 'nano-matter' is formed. This nano-matter constantly shifts and reforms until given new protocols. Jagged, sharp, and dense, Carmina punctures heavily reinforced materials with ease.
