Shipping knives from Philippines to US?

[bjohnjr999]

Hello all, I am hoping someone will have some experience or familiarity with the process of shipping knives from the Philippines to the United States. I am trying to have several compact folding knives (<4" blades) shipped back to the US, however am finding that to be easier said than done. UPS is stating they prohibit the shipment of edged objects, and DHL is requesting a police aviation certificate. Any advice or insight to navigating this is greatly appreciated. Thank you.
