Combat Knife - Known Imperial Patterns of Combat Knife: Astartes Combat Knife - Every Imperial Space Marine is issued one of these blades as soon as he recovers from receiving his gene-seed implants, and he carries it up until his final moment of battle. This large knife -- easily the size of a normal Human's short sword -- holds a mono-molecular edge that never dulls, even through centuries of service. In some Chapters Combat Knives are passed down through the generations, with the deeds of their owners etched upon them. In others, the forging of metal into blade is simultaneous with the forging of a recruit into a Space Marine, and his Combat Knife is laid to rest when he is.Combat Blade - Combat Blade is a catch-all category which describes a variety of lethal hand-to-hand weapons favoured by the warriors of the Space Marine Legions of old, the exact form varying from Legion to Legion by its culture and traditions.Sol Pattern Astartes Combat Knife - The Sol Pattern Combat Knife is a common pattern utilised by the Space Marine Legions during the Great Crusade and Horus Heresy.Catachan Knives - Utilised exclusively by the regiments of the Catachan Jungle Fighters of the Imperial Guard, every Catachan Jungle Fighter learns the craft of making knives from his parents and making one's own knife is considered one of the tests of adulthood on that jungle Death World. While the basic design of the knives remains the same, there are subtle variants between family groups and individuals, depending on the height and preferences of the user. The following are the most common Catachan Knives found throughout the Catachan Jungle Fighters regiments:Catachan Fang - Measuring up to 20 inches of gleaming steel, the Catachan Fang is the most common type of Catachan Knife used by the Catachan regiments. Equally useful for cutting your way through jungle or a deviant Aeldari, the Catachan Fang is renowned throughout thousands of star systems. This knife is also used for settling disputes between Catachans. Usually, one knife is placed in the centre of a fighting pit and the combatants must each strive to get hold of the knife. The duel ends when one fighter draws blood, though this can often mean death as well.Night Reaper - Smaller than other typical designs, the blackened blade of the Night Reaper is especially suitable for infiltration and night missions when light reflecting from a blade can mean the difference between life and death. The blade itself is triangular, so any wound caused by the Night Reaper is unlikely to clot or heal. Catachans are also known to poison these knives using one of the many animal and plant venoms or toxins native to their inhospitable planet.Devil's Claw - Named after the fearsome predator known as the Catachan Devil of the fearsome Catachan jungles, this is the largest type of the traditional knives of Catachan. Anywhere between three and four feet long, the Devil's Claw is closer to a short sword than a knife. It is used mainly on the battlefield in close quarters and it has even achieved a fearsome reputation amongst the Orks, who call it "Da Cutta." The blade itself is hollow and half-filled with mercury to give it greater swinging power. Power Swords wielded by senior members of the Catachan regiments are often identical in design to the Devil's Claw.
