The Rock Saw was a weapon seen in the movie, Dead Space: Downfall and in the game, Dead Space: Extraction.

The Rock Saw seemed to be a mining instrument designed to mine and cut ore from rocks. The front end was a standard metal pick with serrated edges while the back end could be folded out to create a laser for slicing and cutting various materials. Evidently, the laser was quite powerful, demonstrated by the ease by which it sliced through Jennifer Barrow's neck when she committed suicide.

The Rock Saw was the sole melee weapon for all playable characters in Dead Space: Extraction. When retrieved, it was mentioned that the Rock Saw functioned by transforming kinetic force into an electronic discharge, thus amplifying it's physical impact. It was not possible to dismember a Necromorph with the Rock Saw and it may not even be possible to kill them with it. The Necromorphs are certainly capable of taking multiple hits from this weapon with relatively little damage. It's main usage was to interrupt strikes from Necromorphs, particularly when reloading a primary weapon as well as cutting through certain obstacles mainly "fleshy growths" similar to the tentacles used to block the door leading to The Leviathan.


  • The Rock Saw was first seen in Dead Space: Downfall, used by Jennifer Barrow to kill herself. However, until the release of Dead Space: Extraction, the tool was not given an official name.
  • In Dead Space: Extraction, the weapon was first found in the hands of a deranged engineer in Chapter 1.
  • Both the Rock Saw and the Rivet Gun used by Nathan McNeill in Dead Space: Extraction are the same ones used by Sam Caldwell in the first chapter as he was returning them to the evidence locker while escorting Weller's team to the morgue.
  • In Dead Space: Extraction, McNeill was forced to amputate his right arm with his Rock Saw after he was pinned to the ship's hull by a spike launched by the previously defeated Spider.
  • In Dead Space: Extraction, the Rock Saw was used as a melee weapon throughout the game. It could be used to knock back enemies that got too close and to cut through occasional strands of The Corruption.
  • The Rock Saw could also be referenced to as a Laser Pick.
