Sorry guys for this post. Imgur is not playing well with others this morning and then I hit the wrong button and actually posted before I was ready so here's me cleaning up.
To the OP carry and use your mammoth ivory knife. Ivory is much more rugged than its given credit for. I've used mammoth ivory hundreds of times. Elephant only once and it was piano keys. Most of my knives go to working cowboys, folks not known for being easy on gear. Besides making knives for these folks we are these folks. My wife and I along with our partner, have a small cattle ranch in very rugged mountainous terrain. We use our own products on a daily basis.
Some ivory could be a problem though for ruggedness. This set was used on this bowie as I knew this one was going on the customer's mantle.
However this small hunter was made for a Montana hunting guide and packer. This is an edc for him and is used hard. Here it'd been cleaned up a little after taking care of a buck.
This knife was made for a working cowboy and is an edc.
Both of these kitchen knives were made for "foodies" that knew what they wanted. Used daily.
This rancher is one of my test subjects. A good friend he is hard on stuff. This was the first mammoth ivory handled knife I ever made. He carried that knife untill he'd literally sharpened the blade away. He had it and used it daily for years. My wife carved those cuffs by the way.
My wife horseback with her mammoth ivory handled knife in a protype Beltless sheath.
She's bringing in some of the cattle.
She has one headed and my son is tossing the heel loop when we're branding.
Our partner getting ready to rapidly turn this bull calf into a steer. My knives are used hard and mammoth ivory is not an issue.
Of the hundreds of knives I've used this ivory on I have never had one returned for the handle failing, not one. The secret is never to get it hot while working it. As of JUly 1, 2016 here in Kalifornia I will no longer be able to use mammoth ivory or tooth for that matter. This is pie in the sky, sit around the campfire and sing Kumbya conservation. This will not save one elphant from poaching. As a knife maker I have sent knives literally all over the world and have spoken with people with boots on the ground. I could relate some interesting stories that are reality based but the Mods have said no on the ethics.
