I'm still of the opinion that if Randall would issue a statement confirming that they ONLY used certified pre-banned ivory, all Randall knives made with ivory would continue to be legally traded. US F&W won't state what form of proof is required but it only takes the bare minimum to get past seller's burden of proof. Then it would be on F&W to refute that the ivory is pre-ban, which they couldn't do without some type of legitimate proof of their own.
