The mammoth ivory on that S&M is right in my wheelhouse, kj.
I personally do not expect to see a significant drop in mammoth-handled cutlery prices soon, if ever. I think GEC might be going to the sambar stag well a little too often these days and I would like to see a NF-line mammoth knife released in the somewhat near future. I'm almost positive I'd get a safe queen (for reasons kj has mentioned) and a user because a knife with the right kind of mammoth is just too dang pretty not to tote around town.
The owner of the Northwoods name might be pressuring GEC to limit or eliminate any "regular line" mammoth runs, of course. But keep in mind there's always a possibility that mammoth ivory is simply becoming harder to source in the supply chain on account of the animal being extinct and recovery of ivory often being a dangerous and expensive proposition. It's a more organic version of the difficulty sourcing elephant ivory in the States. Instead of bureaucratic hoops that disappear and reappear as the administrations change, it's actual biology doing the limiting.
Either way, prices are headed up-up-up, IMO.
