Kara kesh

The hand device is the Goa'uld's main weapon. The hand device is a golden glove worn on the left hand of the user, with a red gem in the ceter of the palm. It is controlled by a form of telepathy, and only reacts to those with Naquadah in their blood. The hand device has several functions: it can shot a kinetic blast from the gem, throwing a victim back several feet. A beam of energy can also be emmitted from the center gem, which the Goa'uld use as both a method of torture and execution. Hand devices can also project personal energy shields which protect the wearer, and can activate ring transporters. While Jacob Carter/Selmak used a hand device in the search for Seth, the Tok'ra do not seem to use the weapon much.
