its about 10mm longer than my forearm,the ends are quite rounded from wear as it came from the filter system at the tweed heads/fingal sand pumping facility,we service the bins that collect the debris from the pump like driftwood/kelp/filp flops/beer cans and other stuff lost in the ocean,a few people have drowned and not been found along that stretch?i showed it to the police station and they took details and will check it out.
