My Boomerang

I like sometimes carve or make something of wood, and today i show you my boomerang. I decorated it with Quetzalcoatl or feathered snake  from Aztec mythology. When it is thrown it come back, but against common opinion, boomerang come back only when it is thrown in proper way, even best not come back when is thrown wrong. Boomerangs used for hunting and fight not came back and was heavier on one side. As curio i write you also that boomerangs was used not only in Australia, but on whole world, and eldest was found in Poland, was made of mammoth tusk and have more than 20000 years.
