Sith lightsabers or Sith sabers are lightsabers wielded by the members of the Sith Order. The Sith was an ancient religious order of force welders devoted to the dark side of the Force. Sith lightsabers were constructed through methods similar to other lightsabers but the underlying philosophy was different. Sith could not establish a mutual bond with kyber crystals. Their concentration was clouded with the dark side emotions, like fear and hate. A red saber is no different than any other except… it has been made to bleed.
