The Chaos star itself is a tool. I think someone misunderstood within the line of communication and like the game "telephone", you wound up with a distorted message.
The chaos symbol, better known as an 8 point star is far from isolated to chaos magick. It is the infamous compass! North, North/East, East, South/East, South, South/West, West and North/West. Its very common around the world however predominantly seen in the Norse and Celtic cultures as an 8 point symbol for 8 worlds and 8 winds/directions. So basically, it is the all and the here and now. It's everywhere and one spot. It's energy shoots out to every direction, every realm of existence, and the center is you. Pretty neat eh? So it IS a tool in itself that directs energy of a ritual, spell, thought, etc to every corner of the Universe. That's a powerful tool indeed!
But sorry, no "poof!" *wicked tool appears out of thin air*
