The Fiend’s Fang is a sinister, curved dagger with a blade that resembles a demon's tooth, featuring a jagged edge and a serrated back. The handle is wrapped in dark, scaly leather, possibly from a fiendish creature, with a pommel shaped like a small skull. The blade has a dark, almost black metallic finish with subtle crimson veins that pulse faintly, as if alive. The overall design is both menacing and ornate, with intricate engravings of infernal runes along the blade's length.
