Wolfsangel or Crampon is a heraldic charge from mainly Germany and eastern France, which was inspired by medieval European wolf traps that consisted of a Z-shaped metal hook that was hung by a chain from a crescent-shaped metal bar. The stylized symbol of the Z-shape can include a central horizontal bar to give a Ƶ-symbol, which can be reversed and/or rotated (ꑭ); it is sometimes mistaken as being an ancient rune due to its similarity to the "gibor rune" of the pseudo Armanen runes.
