A d'k tahg is a Klingon dagger used in combat. The weapon consists of a single straight blade and two smaller hinged blades at the handle. The d'k tahg has great ceremonial value among the Klingon culture and bears an emblem of it's owners house. A d'k tagh is also used to settle arguments via two Klingons engaging in combat. (GKN novel: A Good Day to Die) Stealing another Klingon's d'k tahg is considered an insult to it's owners honor.
