just recently acquired this old boomerang which was collected from Australia in the 1920s and was known to be an old one then , what I cant figure out is why it has notches/tally marks cut out on one side , I don't think this is a fighting boomerang , maybe they were to represent important ceremonies ?
any info would be very welcome Last edited by chiefheadknocker; 7th January 2018 at 07:11 PM. Reason: extra pic |

Could these possibly be tally-marks used to keep count of animals taken when using this particular piece for hunting?

Could they be for aerodynamic speed and lift?

Vortex generators are often used on the leading edge of aircraft wings to permit the wing to operate efficiently at low speeds. If these notches have a similar effect, it would keep the boomerang flying at lower rotational speeds, presumably.

I dont think so, because the notches are on the trailing edge, not on the leading edge. I simply think, the notches are either a kind of simple decoration or (better idea) made for more grip during the throw. Roland |
