It appears to be somewhere between the 211-V and Isaac's Makeshift Cutter in size and aesthetics. The third version shown is an unknown model. It is unknown what happened to it afterwards, but it can be assumed that Isaac most likely discarded it in a favor of a 'real' Plasma Cutter. Isaac continued to use this weapon throughout his escape from the station. These covers open when the weapon is activated. Its emitter has covers that retract over its front, presumably to prevent accidental discharge while not in use. Isaac used a flashlight he had acquired earlier as a power source for the cutter, quickly attaching the two to fight off an attacking Slasher. Built by Isaac Clarke during an outbreak on The Sprawl, it was originally a medical device that was used in surgeries. The second version shown in the series is a Makeshift Plasma Cutter. Isaac found his 211-V on a bloody workbench on the USG Ishimura. It uses an internal power source, is compact/light enough to be easily portable, and can be even used one handed (due to its light weight). It uses two alignment blades on the side, and three lights on the front, to help the user accurately cut through softer minerals. Designed and manufactured by Schofield Tools, the 211-V is a tool designed to be used in mining operations. The first, and most common, is the 211-V Plasma Cutter. Three different types of Plasma Cutters have been shown in the series:
