“Prosecutors…charged…Shreveport resident John Daniel Graves, with buying the six unaltered walrus tusks, a misdemeanor violation of the Marine Mammal Protection Act, according to the charges. Only Alaska Natives can sell or buy the raw ivory, most often used to create art and then resold.” That’s not one of Graves’s blades above, but there’s no denying that, in the right hands, ivory — walrus or elephant — can make a for a beautiful tool. The problem is, it can be hard to determine provenance. Over at TTAG, we had plenty of skeptics voice doubts about elephant trunk holsters. And given the amount of poaching that goes on, unless you can be sure what you’re buying is legal, is it worth it?
