Picking up from the last Sci-Fi Do Want, the Predator Shoulder Cannon, we continue on to another science fiction weapon that has plenty of style and coolness factor.
The Chainsword from Warhammer 40k has none of the elegance and sophistication of the Shoulder Cannon. But what it lacks in sophistication it makes up for with big buckets of spinning monomolecular-edged metal teeth.
The Chainsword is something of a Warhammer 40k icon. Simply put it is a large sword that has sharp metal teeth running around the outer edge of the blade, just like a chainsaw. When powered on, the Chainswords roars its angry buzzing across the battlefield, announcing the imminent separation of limbs from limb-owners.
To make it even more deadly (‘cause just strapping a chainsaw to a sword isn’t all that impressive in the 41st millennium), the edges of the teeth are sharpened to be monomolecular. That means that the very edge of the blade is *one molecule thick*, which makes it insanely sharp and able to cut through just about anything short of tank armor.
It’s a brutal weapon that won’t leave the victim with a nice clean cut. No, the Chainsword is going to rip your flesh to shreds as it grinds its way through whatever appendage that has been unfortunate enough to get in its way. Great spouts of blood is pulled from the wound by the whirring teeth, covering both attacker, victim and the general surrounding area in a layer of red (or whatever color blood the victim might have).

The Chainsword is all square corners and sharp teeth. Just what every defender of the Imperium needs |
Indeed, the Chainsword is a nasty and brutal weapon in a universe that is every bit as nasty and brutal.
