Here in the UK, EvilBay won't allow sales of any kind of knife either! Even completely legal small slipjoints, kitchen knives are against ebay's rules!

Back to the ivory, I really can't understand why any tusks collected by the rangers catching poachers are destroyed. The tusks are no use to the elephant any more and the police and rangers chasing the poachers need money to keep up their work. Why don't the allow them to legally sell the tusks and use the money to keep going?
