Chainsword

The chainsword is the preferred close combat melee weapon of many of the military forces of the Imperium of Man.

The chainsword is essentially a sword with powered teeth that run along a single-edged blade like that of a chainsaw. Most versions of the weapon make use of monomolecularly-edged or otherwise razor-sharp teeth. Chainswords are not subtle weapons, and wielding one is a statement in its own right: they are horrific tools of war, designed to bite, tear and eviscerate where more primitive blades merely cut and slice.

Among Mankind's endless armies, the ubiquitous chainsword has found a home in the arsenal of many Astra Militarum officers and Commissars, as well as serving as the weapon of choice for countless warriors among the Adeptus Astartes since the ancient era of the Space Marine Legions in the Great Crusade.
