A French blacksmith who did this knife using a meteorite and mammoth ivory.
Edit: a bit more details on the blade: he melted the meteorite himself, however since the meteorite did not have any carbon and had a really high nickel content or would have make a terrible steel so he added a bit of carbon and some raw iron do dilute the nickel.
Except for that the blade is entirely made from the meteorite.
