SOG Knife

The SOG knife is a knife that appears in the level Victor Charlie in Call of Duty: Black Ops. Mason, Woods and Reznov use the knife to kill Viet Cong silently.

It is unique to this level and is never seen again. It is used during one part of the mission to kill certain enemies, usually in scripted events. Once the player is given a weapon, it will then be replaced with the standard knife. It is basically the main weapon in half the level called Victor Charlie.

This weapon is also available as an Emblem, in the Emblem Editor in Multiplayer.

History
The SOG knife was designed for and issued to the covert Studies and Observation Group personnel during the Vietnam War. Historically, The SOG knife was originally designed by Benjamin Baker, the deputy chief of the CSIO at the time of the Cold War. The blade features a convex false edge on the clip point of a Bowie Knife. The blade was unmarked and supposedly untraceable to country of origin or manufacturer, in order for the U.S. to maintain plausible deniability of covert operations should any SOG members issued a knife become captured.
