Chainsword - Imperial: Acitus Pattern Chainsword - A common pattern Adeptus Astartes chainsword utilised by such Chapters as the Novamarines.Astartes Chainsword - This massive weapon is commonly utilised by Assault Marines. These weapons generally have a flat carapace containing the chain teeth, with only the forward, curved section open where the spinning chain teeth can bite into flesh and bone.Drusian "Crusader" Chainsword - Manufactured by a variety of Forge Worlds, these popular weapons are a familiar sight throughout the edges of the Calixis Sector where memories of Saint Drusus burn brightly. On Drusus Day, many shrines are crowded with multitudes of followers, raising their chainswords (or mock replicas, for the poor or young) in the air in honour of his works and sacrifice. For those who seek to continue Drusus' crusade in the Koronus Expanse, the most common pattern of this weapon uses a curved, cutlass-like blade. Most are a holy silver in colour, and favour a large, spiked basket-guard to better smite the unclean xenos.Eviscerator - Favoured by Ecclesiarchy zealots and Witch Hunters, the Eviscerator is an obscenely large, double-handed chainsword fitted with a crude version of the disruption field generator more commonly found on power weapons. Although very unwieldy and tiring to use, the Eviscerator is fully capable of ripping an armoured man in half or tearing open the most blasphemously corrupted mutant in a single stroke. Even more massive versions of these two-handed weapons are also in limited issue in Space Marine Assault Squads, and though similarly unwieldy in combat, when combined with the enhanced strength of the Astartes, they are fully capable of tearing apart the hull plating of even heavily armored vehicles with ease.Frost Blade - Frost Blades are potent weapons unique to the Space Wolves Chapter, and can carve through the heaviest armour with ease. Frost Blades usually take the forms of chainswords or chainaxes, though they can exist in the form of any type of Imperial melee weapon. Frost Blades are master works created by the Space Wolves' Iron Priests -- each is incredibly rare and prestigious. The teeth of these icy chain weapons are always cut from nigh-unbreakable substances such as Ice Kraken fangs or tempered diamond. The unique power fields enveloping Frost Blades have a distinctive blue cast. A Frost Blade combines the best qualities of a Chain Weapon and a Power Weapon. Some Frost Axes have blades of energised diamond rather than chainblades, which gives the weapons the appearance that they have been carved from a single, lethal shard of ice.Gore Prow Pattern - A notable Chapter subtype pattern chainsword known to be utilised by the zealous Fire Hawks Chapter.Hecate Pattern Chainsword - This pattern of chainsword weighs a full 6 kilograms but remains a well-balanced weapon useful in melee combat that is often used by Rogue Traders to intimidate foes and mutinous crew members alike.Hydraphur-Pattern Chainsword - Sometimes called a chain-cutlass, these short-bladed, curved chainswords are favoured by Navis Imperialis armsmen crew chiefs for their brutality. Their shorter length makes them easier to wield in the close confines of a starship corridor, while their more compact design conceals two parallel rows of teeth, allowing it to deal greater damage than its size might otherwise suggest, at the cost of poorly-distributed balance.Locke Pattern Double-Edged "Mercy" Chainsword - Some of the more maniacal wielders of chainswords use customised models with two ripping edges, created by removing the protective carapace surrounding the near side of the weapon. This modification (also available as a finished product due to demand) makes the weapon dangerous to the user as well, but this is not generally a concern and wielders proudly wear the numerous self-inflicted scars that using such a sword often entails. "Mercy" chainswords typically come with a longer haft, so that they can be swung using two hands for deeper strikes.Mark IID "Errant" Pattern Chainsword - A notable Chapter subtype pattern chainsword known to be utilised by the Marines Errant Chapter.Mark V "Fangmaw" Pattern Chainsword - A notable Chapter subtype pattern chainsword utilised exclusively by the savage Space Wolves Chapter.Mark VII "Emperor's Wrath" Pattern Chainsword - A standard Adeptus Astartes pattern of chainsword often used by the Ultramarines Chapter and their successors.Mark XI "Hell's Teeth" Pattern Chainsword - This pattern of the weapon is the most current version of the chainsword used by Imperial military forces.
