Hara'kesh

The hara'kesh is a weapon used almost exclusively by the Ashrak. The device fits snuggly around the middle and ring finger, is capable of detecting a Goa'uld or Tok'ra symbiote. When activated, it emits a beam that causes incredible pain, and is considered a debasing form of execution. It presumably requires naquadah within the bloodstream, similar to the hand and healing device. Sokar used the weapon on Apophis before his escape.
