A knife or dagger was a bladed mêlée weapon or tool used by many humanoid races and cultures. Because of their effectiveness compared to other blunt hand-held weapons, knife weapons are usually common in cultures that have developed the ability to work metal, and often remain in use even after projectile weapons are developed.
Even before the development of metal, many primitive cultures were known to craft knives from stone. The phrase "stone knives and bearskins" was used by Spock to describe the technology available in the 1930s era. The phrase describing primitive artifacts was fresh in James T. Kirk's mind when he found a aged sheaf of old-style letters from his father after returning to Earth shortly after the time travel to the 1930s. (TOS episode: "The City on the Edge of Forever"; TOS novel: Final Frontier)
