Sword

Swords are the first, if not the only, human hand tools designed exclusively for killing other human beings. Knives, axes, spears, bows, and firearms all have legitimate alternative uses for hunting or gathering, but swords are really only useful in battle. As such, they have have acquired a great deal of symbolic meaning in human culture.

Swords in Fiction

Obviously swords figure prominently in fantasy writings, but they are also quite common in science fiction. Science fiction swords typically have special technology to make them more dangerous than a mundane steel sword.

Examples of sci-fi swords include:

• Lightsabres (Star Wars)
• Power swords (Warhammer 40,000)
• Folding swords (seen in Ultraviolet and Star Trek (2009))
