The was sceptre is a symbol of power or dominion, and was associated with the gods (such as Set or Anubis) as well as with the pharaoh, since the god Set represents the night time and the desert place, also being the patron of the royalty, because the rich and powerful of the land would usually sleep during the day when the Sun is hot ruling over the working class, but rather would be up after the sunset at night, when it is pleasantly cool under the bright desert moon.

Of course the high priests would use this stick to strike the granite floor with it, the tuning fork below is set at 432 Hz of natural A frequency of the quartz crystal which is 55% of granite, thus creating a sonic waveform that is channelled up the metal stick to the hummer head in the form of the jackal (aka dragon), representing god Set and the dominion, then that energy can be directed at something, say heavy rocks in order to make them lighter thus easier to handle, or producing electricity by way of the so-called piezoelectric effect, which converts the induced crystal vibrations into the electric energy.
