AppearanceEditThe Great Knife resembles a giant, rusty chef's knife. The handle of the weapon is continuous with the sharpened edge of the blade, which, considering the weight of the weapon, makes it rather top-heavy. The weapon is commonly heard before it's wielder is seen, being dragged along the floor. The blade is similar to the knife James gets from Angela Orosco before his first fight with "that red pyramid thing".
The Great Knife was used by Pyramid Head for the first half of the game. It was first seen when Pyramid Head attacks James in the stairwell of the Blue Creek Apartments. It isn't seen again until James reaches the labyrinth underneath the Silent HIll Historical Society, where James can find it sitting on a bench in what has been dubbed "Pyramid Head's room".
It's next appearance was during Silent Hill 4: The Room, where it was used by Walter Sullivan as the "heavy tool" for the Ritual of the Holy Assumption. It was found by Harry Townshend in a secret room of inside his apartment. After this it was used by Pyramid Head in the Silent Hill film and it's sequel, Silent Hill Revelations. It's appearance changes in both of these: in Silent Hill, it's a single solid blade with a handle at one end, whilst in Revelations, it appears very similar to a katana.
It then appeared in Silent Hill: Book of Memories', where it is dropped by Pyramid Head after he's killed. The final appearance in the series to date was the final issue of the comic Sinner's Reward, where Pyramid Head uses it to kill Finn Conway before he can shoot Jack Stanton
