Or maybe
HAND DEVICE (aka Ribbon Device)
(Also from gateworld)
A weapon used by Goa'uld, also known as a "ribbon device." The device is a useful means of interrogation and can inflict great pain. It is capable of emitting a powerful blast of energy to send a foe hurtling across the room. It is also capable of directing a much less intense, yet very deadly, ribbon of energy -- usually directed to the victim's forehead. Extended exposure is lethal.
The device works largely through the user's thought or emotion, theoretically allowing the user to communicate a message to his or her victim, if held in an extended "grip" of less intense energy.
The user must have naquadah in their bloodstream to make the device work, limiting its use primarily to Goa'uld and Tok'ra.
And you can blame my partner at work for this last one. When not on calls, we've been watching the DVDs from Stargate SG-1.
