The Thogk was a traditional Gamorrean club that literally translated to "log with a spike in it" in Gamorrese. The Gamorrean males who made a Thogk took great pride in forcing a metal spike into a piece of gorgt wood with their fists. If a piece of gorgt wood was not available a Gamorrean might make one out of other timber.
The Gamorrean Dark Jedi Gorc had a lightsaber that resembled the basic shape of a Thogk.
