I had High Desert Horses Custom Knife & Leather Shop do a sheath for me, once. They are located at the Boise Stage Stop, near Boise Idaho, which is one of the last remaining independent truck stops.
I was going to link to the website, but it appears to be down.
At any rate, I was able to place my order in person; as I didn't have time to wait, he just traced the shape of the knife.
He was supposed to mail me the finished product, but I had the misfortune of placing my order just before he moved from one part of the building to the other, and he lost the ticket. But, I went back in, and showed him my ticket. He was visibly and appropriately embarrassed by the mistake. My order immediately became top priority. I told him that I was going to have breakfast, and that I would check back, afterwards.
That man delivered the sheath to me, in the restaurant, before my food got there. It's a pretty basic sheath; nothing fancy, (Which probably lent to the rapid construction) which was what I wanted; a fairly inexpensive and sturdy sheath.
I wish that I knew of someone a little more local, but I do not. If I recall correctly, the guy is happy to take orders over the phone, or probably Facebook. And, being that he operates from a truck stop, shipping is a standard feature.
