Supernatural, Silver Demon-Killing Knife

replica movie prop

Prior to the appearance of Ruby's powerful knife in third season episode The Magnificent Seven, it was believed that demons could only be removed from the earthly plane by exorcism from human hosts, or by shooting them with The Colt.  This blade, unlike a normal knife, can actually kill a demon, although it will also kill the human meatsuit the demon inhabits. Ruby, at this point only a mysterious unnamed female hunter, kills three of the Seven Deadly Sins with her supernatural dagger, and then disappears again. The weapon is seen slaying and/or torturing demons in multiple episodes throughout the rest of the series, as used by Ruby, the Winchesters, Bobby, and by demons against others of their own kind. This 'ancient demon-killing knife of the Kurds', as described by Henry Winchester, is ineffective against Angels.

Silver-plated stainless steel blade with acid-etched runes, silver-plated stainless steel cross guard, and staghorn handle.
